This invention relates to a dock and corresponding methods, and in particular to a dock
for a replaceable fluid container for an engine and a method of supplying fluid to a
vehicle engine.
Many vehicle engines use one or more fluids for their operation. Such fluids are often
liquids. For example, internal combustion engines use liquid lubricating oil compositions.
Also, electric engines use heat exchange liquids for example to cool the engine and/or to
heat the engine, and/or to cool and heat the engine during different operating conditions.
Such fluids are generally held in reservoirs associated with the engine and may require
periodic replacement.
Conventional periodic replacement of engine lubricating oil composition in a vehicle
engine usually involves draining the composition from the engine sump. The process
may also involve removing and replacing the engine oil filter. Such a procedure usually
requires access to the engine sump drain plug and oil filter from the underside of the
engine, may require the use of hand tools and usually requires a suitable collection
method for the drained lubricating oil composition. This is complex and expensive.
Aspects of the disclosure address or at least ameliorate at least one of the above issues.

guiding mechanism may comprise an actuator configured to cooperate with a
complementary guiding mechanism of the fluid container, the actuator being configured
to be operated between: a first condition where the actuator is configured to abut with the
complementary guiding mechanism of the fluid container to hold the fluid container such
that the port of the container is in an undocked condition from a docking interface of the

The dock may further comprise a receiver for accommodating the fluid container in the
undocked condition and in the engaged condition. The receiver may comprise an
asymmetric engaging mechanism configured to cooperate with a complementary
asymmetric engaging mechanism of the fluid container, such that the fluid container may
be accommodated in only one spatial orientation with respect to the dock. The

The disclosure extends to methods and/or containers and/or docks and/or systems
substantially as herein described with reference to the accompanying drawings.
Any feature in one aspect of the disclosure may be applied to other aspects of the
disclosure, in any appropriate combination. In particular, features of method aspects may

Common features are identified by common reference numerals. In the drawings, like
reference numerals are used to indicate like elements.
Fig. 1A and Fig. 1B schematically illustrate a dock 500 for a replaceable fluid container 2,
for example for providing fluid to an engine 50. The engine 50 may be for example an
engine of a vehicle 100.
The fluid container 2, described in more detail below, comprises a first end 10 and a
second end 11 . The container 2 also comprises at least one fluid port 456 provided in the
first end 10 and comprising a coupling 7 adapted to connect to a corresponding coupling
8 on the vehicle 100. As will be explained in greater detail below, the container 2 may
comprises for example three fluid ports or more. The connection between the coupling 7
and the coupling 8 is configured to connect the fluid container 2 in fluidic communication
with a fluid circulation system 1 of the engine 50.
In the examples illustrated in Fig. 1A and 2A, the port 456 is shown as being a male
element and the coupling 8 as a female element. It is understood that the port 456 may
be a female element and the coupling 8 as a male element, as explained in reference to
Fig. 5 and Fig. 6.
In some non-limiting examples, the fluid container 2 may also comprise a data provider
20 arranged for data communication with a control device 2 1 of the vehicle 100 when the
container 2 is engaged with the dock 500 (Fig. 1B). The data provider 20 is described in
greater detail below.
In some examples, the fluid container 2 comprises a reservoir 9 for holding a fluid 3. The
reservoir 9 of the container 2 may be pre-filled with the fluid 3 before the container 2 is
inserted in the dock 500.
The fluid 3 may be any type of fluid circulated in the engine 50 and/or circulated in any
fluid circulation system associated with the engine 50 (that is the fluid is not necessarily
circulated in the engine 50) to support a function of the engine 50 and/or the vehicle 100.
The function may be an ancillary function of the engine 50. For example the fluid 3 may
be lubricant, and/or coolant, and/or de-icer, and/or any hydraulic fluid such as a fluid
used in braking systems, and/or a pneumatic fluid, a washer fluid, a fuel additive or any
other fluid associated with any function of the engine and/or the vehicle. Many different
types and grades of such fluid are available. As already mentioned, in some non-limiting
examples, the fluid 3 may be an engine lubricating oil composition or an engine heat
exchange fluid.
As illustrated in Figures 1A and 2A, in a disengaged condition, the container 2 may be
conveniently seated in the dock 500 and/or removed from the dock 500 by a user and/or
operator.
To that effect, the dock 500 comprises a fastening mechanism 44 configured to cause
the container 2 to cooperate with the dock 500 in the disengaged condition (Fig. A).
In the disengaged condition, the fastening mechanism 44 is configured to hold the fluid
container 2 such that the fluid port 456 of the container 2 is in an undocked condition
from a docking interface 501 of the dock 500. For example, in the undocked condition,
the container 2 and the docking interface 501 are not fastened to each other, for instance
the container 2 and the docking interface 501 may be just touching or be spaced from
each other. In the undocked condition, the container 2 is inserted into the dock 500, and
the fastening mechanism 44 is configured to act first to seat the fluid container 2 in the
dock 500 but in the undocked condition.
The fastening mechanism 44 of the disclosure may thus enable easy insertion and/or
removal of the container 2 from the dock 500 in the disengaged condition.
The fastening mechanism 44 is also configured to cause the container 2 to cooperate
with the dock 500 in an engaged condition (Fig. 1B).
In the engaged condition, the fastening mechanism 44 is configured to hold the fluid
container 2 in a docked condition with the docking interface 501 of the dock 500. In the
engaged condition, the container 2 cannot be conveniently removed from the dock 500
by a user and/or operator. The fastening mechanism 44 is thus configured to cooperate
with the container 2 such that, as the container 2 is inserted further into the dock 500, the
fastening mechanism 44 is configured to act to bring the fluid container 2 into an
engaged condition in which the fluid container 2 is docked with the docking interface 501
of the dock 500.
In some non-limiting examples, in the engaged condition, the data provider 20 may be
arranged for data communication with the control device 2 .
In some non-limiting examples, the fastening mechanism 44 may further act as a locking
mechanism, as explained in greater detail below.
As schematically illustrated in Fig. 2A and Fig. 2B, the fastening mechanism 44 may
comprise an actuator 45 configured to cooperate with a complementary fastening
mechanism 442 of the fluid container 2.
The actuator 45 may be configured to be operated between a first condition (Fig. 2A)
and/or a second condition (Fig. 2B).
In the first condition, the container 42 may be conveniently seated in and/or removed
from the dock 500 by the user and/or operator.
To that effect, in the first condition, the actuator 45 is configured to abut with the
complementary fastening mechanism 442 of the fluid container 2, in order to hold the
fluid container 2 such that the port 456 of the container 2 is in an undocked condition
from a docking interface 501 of the dock 500.
In the second condition, the actuator 45 is fastened to the complementary fastening
mechanism 442 of the fluid container 2, for example using cooperating fastening
mechanisms, such as latches, on the container 2 and on the docking interface 501, such
as resilient and/or biased mechanisms cooperating and/or interlocking with conforming
and/or cooperating mechanisms, such as indents and/or grooves. As a result, in the
second condition of the actuator 45, the container 2 cannot be removed from the dock
500. The actuator 45 needs to be in the first condition to enable the container 2 to be
removed from the dock 500.
In some examples, the actuator 45 may comprise at least one lever 14. The lever 14 may
be any type of fastening arm or linkage with the container 2, such as for example a cam.
As a non-limiting example, the lever 14 may comprise a shaft 142, mounted to be able to
rotate with respect to the docking interface 501 , and at least one arm 141 provided on
the rotating shaft 142.
The complementary fastening mechanism 442 of the container 2 may comprise a lever
engaging surface 442 configured to cooperate with the lever 14. The lever engaging
surface 442 may be any type of cooperating surface. As a non-limiting example, the lever
engaging surface 442 may comprise an arm engaging surface 142 provided on the
container 2, such as a groove provided on the container 2.
As schematically illustrated in Fig. 2A and 2B, the actuator 45 is configured to be
movable (as shown by arrows A1) with respect to the docking interface 501 in order to
guide the fluid container 2 from the disengaged condition (Fig. 2A) into the engaged
condition (Fig. 2B). As a non-limiting example, movement of the actuator 45 may cause
the shaft 142 to rotate with respect to the docking interface 501 . The rotation of the shaft
142 causes the arm 141 cooperating with the groove 142 to displace the container 2, to
engage the container 2 with the docking interface 501 , as shown by arrow B .
Additionally or alternatively, in some examples, the actuator 45 may further be configured
to be movable (as shown by arrows A2) with respect to the docking interface 501 in order
to guide the fluid container 2 from the engaged condition (Fig. 2B) to the disengaged
condition (Fig. 2A). As a non-limiting example, movement of the actuator 45 causes the
shaft 142 to rotate with respect to the docking interface 501 . The rotation of the shaft 142
causes the arm 141 cooperating with the groove 142 to displace the container 2 to
disengage the container 2 from the docking interface 501 , as shown by arrow B2.
In some examples, the actuator 45 is configured to guide the fluid container 2 from the
disengaged condition (Fig. 2A) to the engaged condition (Fig. 2B) in a direction (as
shown by arrow B1) normal to the docking interface 501 of the dock 500. To that effect,
the dock 500 may comprise a guiding mechanism 44 configured to control engagement
of the fluid container 2 into the dock 500 from the disengaged condition to the engaged
condition.
Additionally or alternatively, the actuator 45 may be configured to guide the fluid
container 2 from the engaged condition (Fig. 2B) to the disengaged condition (Fig. 2A) in
a direction (as shown by arrow B2) normal to the docking interface 501 of the dock 501 .
To that effect, the dock 500 may comprise a guiding mechanism 44 configured to control
disengagement of the fluid container 2 into the dock 500 from the engaged condition to
the disengaged condition.
The actuator 45 of the fastening and/or guiding mechanism 44 of the disclosure may thus
enable level displacement of the container 2 with respect to the dock 500, for example in
a direction normal to the docking interface 501 . The level displacement of the container 2
with respect to the dock 500 may enable correct coupling of all of the fluid ports 456 of
the container 2, therefore avoiding undesirable leakage of the container 2. The level
displacement of the container 2 with respect to the dock 500 may enable simultaneous
coupling of all of the fluid ports 456 of the container 2, therefore avoiding undesirable
leakage of the container 2.
To that effect, the actuator 45 may comprise at least two levers 14 provided on opposing
parts of the actuator 45. The at least two levers 14 may be operated simultaneously, for
example with respect to a mid-plane (O-O) as shown in Fig. 2A and Fig. 2B. The at least
two levers 14 may be configured to cooperate with two corresponding lever engaging
surfaces 442 of the fluid container 2. The symmetrical location and the simultaneous
movement of the two levers 14 with respect to the plane (O-O) may thus enable the level
displacement of the container 2 with respect to the dock 500 as mentioned above, with at
least one of the associated advantages.
Additionally or alternatively, as illustrated in Fig. 4A and Fig. 4B, the actuator 45 may
comprise at least two levers 14 provided on opposing parts of the actuator 45, for
example with respect to a mid-plane (O'-O'), perpendicular to the plane (O-O) of Fig. 2A
and Fig. 2B. The at least two levers 14 may be operated simultaneously, for example
with respect to the mid-plane (O'-O') as shown in Fig. 4A and Fig. 4B. For example the at
least two levers 14 may comprise two arms 141 provided on the same rotating shaft 142.
The at least two levers 14 may be configured to cooperate with two corresponding lever
engaging surfaces 442 of the fluid container 2. The symmetrical location of the two levers
14 with respect to the plane (O'-O') may thus enable the level displacement of the
container 2 with respect to the dock 500 as mentioned above, with at least one of the
associated advantages.
Therefore, in a non-limiting example, the actuator 45 may comprise fours levers 14, that
is two levers 14 provided on opposing parts of the actuator 45 with respect to the plane
(O-O) of Fig. 2A and Fig. 2B, and two levers 14 provided on opposing parts of the
actuator 45 with respect to the plane (O'-O') of Fig. 4A and Fig. 4B. The symmetrical
location of the four levers 14 with respect to the planes (O-O) and (O'-O') may thus
enable the level displacement of the container 2 with respect to the dock 500 as
mentioned above, with at least one of the associated advantages.
Additionally or alternatively, as illustrated in Fig. 2A, 2B, 3A, 3B and 3C, in some
examples, the fastening and/or guiding mechanism 44 of the dock 500 may further
comprise a receiver 502 for accommodating the fluid container 2 in the disengaged
condition (Fig. 2A and Fig. 4A) and in the engaged condition (Fig. 2B and Fig. 4B). In
some examples, the receiver 502 may comprise at least one lower wall configured to
cooperate with the end 11 of the container 2 and/or at least one lateral wall configured to
cooperate with the lateral walls of the container 2. The receiver 502 may act as a guide
for the container 2 and may thus enable the level displacement of the container 2 with
respect to the dock 500 as mentioned above, with at least one of the associated
advantages.
Additionally or alternatively, the receiver 502 may comprise an asymmetric engaging
mechanism 503 configured to cooperate with a complementary asymmetric engaging
mechanism 52 of the fluid container 2, such that the fluid container may be
accommodated in only one spatial orientation with respect to the dock 500.
The dock 500 may thus prevent the container 2 to be inserted in the dock 500 in an
incorrect orientation with respect to the dock 500. The dock 500 may thus prevent the
incorrect coupling of the container 2 to the fluid circulation system 1 of the engine 50.
As illustrated in Fig. 3A, the asymmetric engaging mechanism 503 may comprise a first
number (for example one (1)) of patterns 504 provided in one part 101 of the receiver
502 and a second, different, number (for example two (2)) of patterns 505 provided in
another part 102 of the receiver.
Alternatively or additionally, as illustrated in Fig. 3B, the asymmetric engaging
mechanism 503 may comprise at least one pattern 504 with a first shape (for example a
triangle) provided in one part 101 of the receiver 502 and at least one pattern 505 with a
second, different, shape (for example a rectangle) provided in another part 102 of the
receiver 502.
Alternatively or additionally, as illustrated in Fig. 3C, the asymmetric engaging
mechanism 503 may comprise at least one pattern 504 with a first dimension provided in
one part of the receiver 502 and at least one pattern 505 with a second, different,
dimension provided in another part 102 of the receiver 502.
In some examples, the parts 101 and 102 may be opposing each other with respect to
the plane (O-O) or the plane (O'-O').
As illustrated in Fig. 4A and Fig. 4B, in some examples the asymmetric engaging
mechanism 503 may be tapered towards the docking interface 501 of the dock 500. The
tapered geometry may enable the asymmetric engaging mechanism 503 to be
configured to provide clearance c between the asymmetric engaging mechanism 503 of
the dock 500 and the complementary asymmetric engaging mechanism 52 of the fluid
container 2 for enabling a user and/or operator to easily engage the complementary
asymmetric engaging mechanism 52 of the fluid container 2 with the asymmetric
engaging mechanism 503 of the dock 500. This may enable easy and convenient
insertion of the container 2 in the dock 500. The tapered geometry may enable the
asymmetric engaging mechanism 503 to guide the fluid container 2 from the disengaged
condition into the engaged condition into the docking interface 501 in a well-defined and
tight manner in the docking interface 501 .
In some examples, the actuator 45 may further comprise at least one handle 17 coupled
to the lever 14. As illustrated in Fig. 2A and Fig. 2B, the handle 17 may be configured to
be operated by a user to cause the actuator 45 to be operated from the first condition
(Fig. 2A) to the second condition (Fig. 2B).
Alternatively or additionally, the handle 7 may further be configured to be operated by a
user to cause the actuator 45 to be operated from the second condition (Fig. 2B) to the
first condition (Fig. 2A).
The handle 17 may be located at a proximal end of the actuator 45. The location of the
handle 7 at the proximal end of the actuator 45 may enable convenient operation of the
handle 17 by a user and/or operator.
As illustrated in Fig. 2B, the handle may further be configured to cover at least partly the
part 11 of the fluid container 2 when the container 2 is in the engaged condition. The
covering of the part 11 of the fluid container 2 may prevent accidental and/or
unintentional extraction of the container from the dock 500 in the engaged condition.
In the examples of Fig. 2A and Fig. 2B, the handle 17 may be coupled to the lever 14 via
an elongate actuator member 12 of the actuator 45.
As schematically illustrated in Fig. 2A, in the first condition, the actuator 45 may be
configured to abut with the complementary fastening mechanism 442 located at the part
10 of the fluid container 2 arranged to be docked to the docking interface 501 of the dock
500 in the engaged condition, that is the distal end 10 of the container 2 and the distal
end of the actuator.
The location of the complementary fastening mechanism 442 and the lever 14 at the part
10 may enable minimise tolerance stack between the container 2 and the dock 500, and
thus may enhance tight cooperation of the container 2 and the docking interface 501 of
the dock 500.
In some examples, in the disengaged condition, the fastening mechanism 44 may be
further configured to hold the fluid container 2 such that the fluid port 456 of the container
2 is spaced from the docking interface 501 of the dock 500, for example by a distance d.
The fastening mechanism 44 may thus prevent the fluid port 456 of the container 2
and/or a port 8 1 of the system 1 locating on the dock 500 to be damaged by a shock
between the container 2 and the dock 500 if the container 2 is dropped, for example
accidentally, in the dock 500.
The dock 500 may comprise a guiding mechanism 44 configured to guide the fluid
container 2 toward the position seated (for example Fig. 1A and Fig. 2A) within the dock
500 to enable the fluid container 2 to be docked to the docking interface 501 of the dock
500 in the engaged condition.
As already mentioned, alternatively or additionally, the dock 500 comprises the guiding
mechanism 44 configured to control engagement of the fluid container 2 into the dock
500 from the disengaged condition to the engaged condition and/or from the engaged
condition to the disengaged condition.
In embodiments, the fastening mechanism and the guiding mechanism may be at least
partly combined in the actuator 45 and/or the receiver 502.
The dock 500 may be provided on a vehicle 100 or on a carrier. One or more docks 500
may be provided on the vehicle 100 or the carrier.
In the case where the dock 500 is provided on a vehicle 100, the dock 500 may further
comprises at least one fluid port, such as the fluid port 81, comprising the coupling 8
adapted to connect to the corresponding coupling 7 on the fluid container 2 to connect
the fluid container 2 in fluidic communication with the fluid circulation system 1 of or
associated with the engine 50.
The dock 500 may be provided directly proximate to the engine 50, but may also be
provided away from the engine 50, such as in the boot of the vehicle 100.
The dock 500 may further comprise an interface 2 1 for data communication with the data
provider 20 of the fluid container 2.
In the case where the dock 500 is provided on a carrier, such as a pallet, for recycling
and/or analysing and/or servicing of the container 2, the dock 500 does not need to
comprise a fluid port, but in some examples the dock may also comprise a fluid port, for
example for emptying the container 2, for example before recycling of the container
and/or fluid 3. In some examples the carrier may be any carrier located on any
transportation device; in a vehicle service centre; in an analysing facility; and/or in a
recycling facility.
As illustrated in Figure 5 the fluid container 2 may comprise a filter 90. The container 2
illustrated in Fig. 5 comprises, at the first end 10, at least one fluid outlet port 5, at least
one fluid inlet port 4 and at least one vent port 6 in which, each of said ports 4, 5 or 6
comprises couplings 7, for example self-sealing, adapted to connect to corresponding
couplings 8 on the dock 500 to thereby connect said container 2 in fluidic communication
with the engine fluid circulation system 1.
Each of said couplings 7 comprises a latch 13 which is biased to a docked position to
thereby retain said container 2 in fluidic communication with said vehicle engine fluid
circulation system 1.
In some examples, each of said couplings 7 may be remotely operable to disconnect
said container 2 from the dock 500, and thus from said vehicle engine circulation system
1. To that effect, the actuator 45 may be configured to cooperate with the complementary
fastening mechanism 442 of the fluid container 2. For examples, the lever 14 of the
actuator 45 may cooperate with the groove 442 of the container 2. As explained in
greater detail below, movement of the actuator 45 causes operation of the latches 13.
The actuator 45 comprises the elongate actuator member 12 extending between the first
end 10 and the second end 11 of the container 2. Each latch 13 comprises a collar 1
associated with each of said latches 13.
The lever 14 is operable by the handle 7 located at an end of the elongate actuator
member 12 distal from the ports 4, 5, and 6.
Movement of the elongate actuator member 12 of the actuator 45 by pulling on the
handle 17 in the direction shown generally as A 1, causes the elongate actuator member
12 and the lever 14 of the actuator 45 to act, via the groove 442 of the container 12, on
each of the latch collars 15, thereby to operate each of said latches 13, and connect the
container 2 to the engine fluid circulation system 1. The container 2 may then be
connected to the dock 500 in the direction shown generally as B1 .
Alternatively, the handle 17 may be pivotally or slideably mounted with respect to the
dock 500 as a lever for operating the actuator 45.
On the contrary, movement of the elongate actuator member 12 of the actuator 45 by
pulling on the handle 17 in the direction shown generally as A2, causes the elongate
actuator member 12 and the lever 14 of the actuator 45 to act on each of the latch collars
15, via the groove 442 of the container 12, thereby to operate each of said latches 13,
and disconnect the container 2 from the engine fluid circulation system 1. The container
2 may then be removed away from the engine 50 in the direction shown generally as B2.
The container 2 may comprise a handle 18 such that a user may hold the container 2.
After the disconnected container 2 has been removed from the engine 50 and vehicle
100, another container 2 which may contain fresh, refreshed or unused fluid 3 may be
reconnected to the couplings 8. Thus, pressing the replacement container 2 in the
opposite direction B1 to the direction B2 of disconnection causes the self-sealing
couplings 7 to engage and retain the container 2 on the engine 50.
In use, the container 2 is retained in fluidic communication with the vehicle engine fluid
recirculation system 1 by the self-sealing couplings 8.
Figure 6 shows in schematic longitudinal cross-section of non-limiting examples of a selfsealing
coupling 8 and a self-sealing coupling 7 comprising a latch 13 suitable for use in
a dock 500 of the present disclosure.
The coupling comprises a male element 210 and a female element 220. The female
element 220 may be part of a port 456, for example an inlet port 4 (as shown) or
alternatively an outlet port (not shown) or a vent port (not shown) on the container 2. The
coupling comprises the remotely operable latch 13 comprising the collar 15.
The collar 13 has a surface 26 which exerts a radial force in the direction F on balls 27.
ln some examples, the coupling 7 may comprises a self-sealing valve 28 which is biased
to a closed position when the male and female elements 210 and 220 are disconnected,
as shown in Figure 6. The valve 28 comprises an axially moveable element 29 which is
biased to a closed position by the action of a spring 23 acting against a face 3 1 on the
port 4 and a face 32 on the axially moveable element 29. When in the closed position, a
valve face 33 of the axially moveable element 29 bears against a valve seat 34 of the
port 4 to seal a passage 35 to prevent fluid flow through the valve 28. One or either or
both of the valve face and valve seat may comprise a seal 36.
The male element 210 is in fluidic communication with the vehicle engine fluid circulation
system 1 of the engine 50 and comprises a sealing element 37, for example an O-ring.
The male element 210 comprises an indent 38 which may be in the form of an external
groove for receiving the balls 27 when engaged with the female member 220.
As the male element 210 is inserted into the female element, the sealing element 37
engages a circumferential face 39 of the axially moveable valve element 29. This
sealably engages the male and female elements 210 and 220 before the valve allows
any fluid to flow.
As the male element 210 is inserted further into the female element 220, an end 40 of
the male element 210 engages a flange 4 1 (suitably circumferential) on the axially
moveable valve element 29 and further insertion of the male element 210 causes the
male element acting through the male element end 40 and the flange 4 1 to displace the
axially moveable valve element 29 against the action of the biasing spring 23 and
displace the valve face 33 from the valve seat 34 allowing fluid to flow through the
passage 35 and through a duct 42 in the axially moveable valve element 29.
Thus, the self-sealing valve has the characteristic that when the coupling is being
connected, a seal is made between the connecting ports before any valves open to allow
fluid to flow.
As the male element 210 is inserted still further into the female element 220, the male
member acts upon the balls 27 in the opposite direction to F until it is sufficiently
positioned inside the female element 220 for the balls 27 to engage the indent 38. This
latches the male and female members 210 and 220 together and retains the container 2
in fluidic communication with the vehicle engine fluid recirculation systems 1 of the
engine 50. Positioning of the male and female members may be assisted by a flange 43
on the male member 2 10.
ln use to disconnect the male and female members 210 and 220, the actuator member
12 is operated in the direction A2 as illustrated in Fig. 5 and, through the lever 14, axially
displaces the collar 15 of the latch 13 away from the male member 210. The axial
movement of the collar 15 causes the balls 27 to move out of the indent 38 of the male
member 210 and thereby unlatch the male member 210. The container 2 may now be
removed and disconnected from the vehicle engine fluid recirculation system 1. Thus,
displacement of the female element 220 in the direction B2 disengages the balls 27 from
the recess 38. Further displacement of the female element 220 in the direction B2 allows
the axially moveable valve member 29 under the action of the spring 23 to be displaced
and urge the valve face 33 against the face seat 34 thereby preventing flow of fluid
through the passage 35 and duct 42. This seals the valve 28 before the male and female
elements 210 and 220 are disconnected and, in particular, before the seal 37 of the male
member 210 disengages the circumferential surface 39 of the axially moveable valve
member 29.
The container may then be removed from the vehicle (not shown).
As already mentioned, the container 2 may comprise a data provider 20, and in some
non-limiting examples, the data provider 20 may be configured to provide data about the
fluid container 2. In examples the data provider 20 may be coupleable to provide the data
to the control device 2 1, such as an engine control device, via a communication link 97.
The data provider 20 may be positioned on the container 2 so that, when the container 2
is coupled in fluidic communication with the circulation system 1 of the engine 50, the
data provider 20 is also arranged to communicate the data with the control device 2 ,
and if the container 2 is not positioned for fluidic communication with the circulation
system 1, communication with the data provider 20 is inhibited.
In some examples, the data, for example data obtained from the control device 2 1, may
further be provided to a memory. In some examples, the memory may be distributed in
memories selected from a list comprising: a memory 94 of a management device (for
example comprising the control device 21), a memory 104 of the data provider 20 of the
container 2, and/or a memory of the dock 500 for the container 2.
The control device 2 1, for example the engine control device, comprises a processor 96,
and the memory 94 configured to store data.
In examples, the processor 96 may be configured to monitor and/or to control the
operation of the engine, via communication links.
The control device 2 1 may be further configured to obtain a signal indicating that the
container 2 is coupled to the circulation system 1 of the engine 50 and/or data from the
data provider 20 via the communication link 97.
The data provider 20 of the container 2 may comprise a processor 103 arranged to
receive signals from a fluid sensor 93 and/or a latch sensor 30. The processor 103 may
be arranged to communicate the signal indicating that the container 2 is coupled to the
dock 500, and thus the circulation system 1, and/or the data to the control device 2 1 via
the communication link 97. The data provider 20 may further comprise a memory 104 for
storing data describing the fluid 3. In particular, the memory 104 may store data including
at least one of: the grade of the fluid, the type of fluid, the date on which the fluid was
filled or replaced, a unique identifier of the container 2, an indication of whether the
container 2 is new, or has previously been refilled or replaced, an indication of the
vehicle mileage, the number of times the container 2 has been refilled or reused, and the
total mileage for which the container has been used.
The engine 50 may comprise an engine communication interface 106 arranged to
communicate operational parameters of the engine 50, such as engine speed and
throttle position, to the processor 96 of the control device 2 1 via a communication link 98.
The engine communication interface 106 may further be operable to receive engine
command from the control device 2 1 and to modify operation of the engine 50 based on
the received commands.
The memory 94 of the control device 2 1 comprises non-volatile memory configured to
store:
identifiers of acceptable fluids for use in the engine 50;
data defining a first container fluid level threshold and a second fluid level
threshold;
data indicative of an expected container fluid level based on the mileage of the
vehicle;
data defining a service interval, wherein the service interval is the time period
between performing maintenance operations for the vehicle such as replacing
the fluid;
the vehicle mileage;
sets of engine configuration data for configuring the engine to operate in a
selected way;
• an association (such as a look up table) associating fluid identifiers with the
sets of engine configuration data; and
• data indicative of an expected fluid quality based on the mileage of the vehicle.
The processor 96 is operable to compare data stored in the memory 94 with data
obtained from the data provider 2 1 of the container 2 and/or from the communication
interface 106 of the engine 50.
The processor 103 of the container 2 may be configured to obtain data indicating the
expected fluid level based on the mileage since the fluid was last refilled, and to compare
the fluid level sensed by the sensor 93 with stored data. In the event that this comparison
indicates that the fluid level is changing more quickly than expected, the data provider 20
can be configured to send data to the control device 2 1 to modify a service interval for
the vehicle based on this comparison.
Many different types and grades of fluids 3 are available and the data provider 20 may
comprise an identifier of the fluid 3.
The data provider 20 may comprise a computer readable identifier for identifying the fluid
3. The identifier may be an electronic identifier, such as a near field RF communicator,
for example a passive or active RFID tag, or an NFC communicator.
The data provider 20 may be configured for one way communication. For example the
data provider 20 may be configured only to receive data from the control device 21, so
that the data can be provided to the memory 104 at the container 2. For example the
memory 104 may be configured to receive data from the engine control device 21. This
enables data to be stored at the container 2. Such stored data can then be provided from
the memory 104 to diagnostic devices during servicing and/or during replacement of the
container 2. Alternatively the data provider 20 may be configured only to provide data to
the control device 2 1. In some possibilities, the data provider 20 is adapted to provide
data to and receive data from the control device 2 1.
Figure 7 shows an elevation view of a container 2 and a partial section through a wall of
the container 2. The container 2 comprises a body 304, and a base 306. The body 304 is
secured to the base by a lip 302. The data provider 20 may be carried in the lip 302.
The lip 302 may include a data coupling 310 to enable the data provider 20 to be coupled
to the interface 96 for communicating data with the control device (not shown in Figure
7). The interface 96 may comprise connectors 314 for connecting the interface 96 with
the data provider 20 of the container 2.
The base 306 of the container 2 comprises a fluid coupling (not shown in Figure 7) for
coupling fluid from the reservoir 9 of the container 2 with the circulation system 1 of the
engine 50. The fluid coupling and the data coupling 310 are arranged so that connecting
the fluid coupling in fluidic communication with the circulation system 1 of the engine 50
also couples the data provider 20 for data communication with the control device 2 1 via
the interface 96 by seating the connectors 314 of the interface 96 in the data coupling
310 on the container 2.
In some examples, the interface 96 and the connectors 314 may provide electrical
connections for up to eight 8) channels which provide measurements for fluid
temperature, fluid pressure, fluid quality, fluid type, and the level (e.g. amount) of fluid in
the container 2. The connectors 31 may be arranged to provide electrical power to the
data provider 20.
The fastening and/or guiding mechanism 44 may prevent the engine 50 from operating if
the container 2 is disconnected from the engine fluid circulation system 1 and/or to
prevent the container 2 being disconnected from the engine 50 if the engine is operating.
At least one of the ports 4, 5 or 6 may comprise a non-return valve. Suitably, the at least
one outlet port 5 comprises a non-return valve. If the container comprises more than one
outlet port, suitably each outlet port comprises a non-return valve. The non-return valve
in the outlet may prevent fluid from draining back to the container 2 when the engine 50
is not operating and may help keep a fluid line to a circulating pump full of fluid so that
circulation of fluid is immediate when operation of the engine is started.
The fluid inlet port or ports 4 may each comprise a control valve or shut-off valve which
may be closed when the vehicle engine is not operating, for example to prevent or
reduce fluid draining from the container 2 to the engine 50.
The vent port or vent ports 6 may not contain any valves because fluid, for example gas
and/or vapour, may be required to flow both to and from the container through the vent
port or vent ports 6 when the container is connected to the vehicle engine fluid circulation
system 1.
As mentioned, the container 2 may comprise a filter 90 for filtering the fluid 3. This is
suitable when the fluid is an engine lubricating oil composition. Suitable filters 90 may
comprise paper and/or metal filter elements. The filter 90 may be suitable for filtering
particles in the range 1 to 100 microns, suitably in the range 2 to 50 microns, for example
in the range 3 to 20 microns. The filter 90 may comprise a filter by-pass for fluid to
bypass the filter, for example if the filter 90 becomes blocked or unacceptably loaded
with material, which may cause an unacceptable fluid back-pressure through the filter 90.
An advantage of having a filter 90 in the container 2 is that this may allow a larger filter to
be used than if the filter were in a separate container associated with the engine fluid
circulation system 1. This may have one or more of the following benefits: (a) increased
filtration efficiency; (b) finer filtration and (c) increased filter lifetime. Suitably, in use, fluid
enters the container 2 through the inlet port 4 and is passed to the top of the container 2,
for example through at least one conduit in the container 2; some or all of the fluid 3 is
passed through the filter 90 on exiting said conduit; and the totally or partially filtered fluid
is withdrawn from the base of the container through the outlet port 5. The filter 90 may
operate at elevate pressure.
The container 2 may be manufactured from metal and/or plastics material. Suitable
materials include reinforced thermoplastics material which for example, may be suitable
for operation at temperatures of up to 150 °C for extended periods of time.
The container 2 may comprise at least one trade mark, logo, product information,
advertising information, other distinguishing feature or combination thereof. The
container 2 may be printed and/or labelled with at least one trade mark, logo, product
information, advertising information, other distinguishing feature or combination thereof.
This may have an advantage of deterring counterfeiting. The container 2 may be of a
single colour or multi-coloured. The trademark, logo or other distinguishing feature may
of the same colour and/or material as the rest of the container or a different colour and/or
material as the rest of the container.
The container 2 may be a container 2 for a fluid which is a liquid. As already mentioned,
suitable liquids include engine lubricating oil composition and heat exchange fluid for an
electric engine.
The container 2 may be a container for engine lubricating oil composition. Thus, the
container may contain engine lubricating oil composition. In this embodiment, the
container 2 may be provided as a self-contained container containing fresh, refreshed or
unused lubricating oil composition which may conveniently replace a container on an
engine 50 containing used or spent lubricating oil composition. If the container 2 also
comprises the filter 90, this also is replaced together with the spent or used lubricating oil
composition. Thus, a fluid reservoir container 2 containing spent or used lubricating oil
composition retained in fluidic communication with the vehicle engine fluid circulation
system 1 may be disconnected from the vehicle engine fluid circulation system, removed
from the vehicle and replaced by a container containing fresh, refreshed or unused
lubricating oil composition and if present a fresh, renewed or new filter.
The engine lubricating oil composition may comprise of at least one base stock and at
least one engine lubricating oil additive. Suitable base stocks include bio-derived base
stocks, mineral oil derived base stocks, synthetic base stocks and semi synthetic base
stocks. Suitable engine lubricating oil additives are known in the art. The additives may
be organic and/or inorganic compounds. Typically, the engine lubricating oil composition
may comprise about 60 to 90 % by weight in total of base stocks and about 40 to 10 %
by weight additives. The engine lubricating oil composition may be a lubricating oil
composition for an internal combustion engine. The engine lubricating oil composition
may be a mono-viscosity grade or a multi-viscosity grade engine lubricating oil
composition. The engine lubricating oil composition may be a single purpose lubricating
oil composition or a multi-purpose lubricating oil composition.
The engine lubricating oil composition may be a lubricating oil composition for an internal
combustion engine. The engine lubricating oil composition may be a lubricating oil
composition for a spark ignition internal combustion engine. The engine lubricating oil
composition may be a lubricating oil composition for a compression internal combustion
engine.
The container may be a container for heat exchange fluid for an electric engine. Thus,
the container may contain heat exchange fluid for an electric engine. In this embodiment,
the container may be provided as a self-contained container containing fresh, refreshed
or unused heat exchange fluid for an electric engine which may conveniently replace a
container on an engine containing used or spent heat exchange fluid. If the container
also comprises a filter, this also is replaced together with the spent or used heat
exchange fluid.
Electric engines may require heat exchange fluid to heat the engine and/or cool the
engine. This may depend upon the operating cycle of the engine. Electric engines may
also require a reservoir of heat exchange fluid. The fluid reservoir container may provide
a heat storage container in which heat exchange fluid may be stored for use to heat the
electric engine when required. The fluid reservoir container may provide a container for
storage of coolant at a temperature below the operating temperature of the engine for
use to cool the electric engine when required.
Suitable heat exchange fluids for electric engines may be aqueous or non-aqueous
fluids. Suitable heat exchange fluids for electric engines may comprise organic and/or
non-organic performance boosting additives. Suitable heat exchange fluids may be manmade
or bio-derived, for example Betaine. The heat exchange fluids may have fire
5 retarding characteristics and/or hydraulic characteristics. Suitable heat exchange fluids
include phase change fluids. Suitable heat exchange fluids include molten metals or
salts. Suitable heat exchange fluids include nanofluids. Nanofluids comprise
nanoparticles suspended in a base fluid, which may be solid, liquid or gas. Suitable heat
exchange fluids include gases and liquids. Suitable heat exchange fluids include
10 liquefied gases.
The engine 50 may be any type of engine for example for a vehicle and/or may also be a
reverse engine, such as a generator, such as a wind turbine generator.
The container may be suitable for operating at temperatures of from ambient
temperature up to 200 °C, suitably from -20°C to 180°C, for example from -10°C to
15 150°C.
The container may be suitable for operating at gauge pressures up to 15 bar (unit of
gauge pressure, 1Pa=10 bar), suitably from -0.5 bar to 10 bar, for example from 0 bar to
8 bar.
Suitable vehicles include motorcycles, earthmoving vehicles, mining vehicles, heavy duty
20 vehicles and passenger cars.
The fluid reservoir container is advantageous where rapid replacement of the fluid is
required or advantageous, for example in "off-road" and/or "in field" services.
Although the example shown in Figure 7 comprises conductive electrical connections
314 for communicating with the data provider 20, a contactless connection may also be
25 used. For example, inductive or capacitive coupling can be used to provide contactless
communication. One example of inductive coupling is provided by RFID, however other
near field communications technology may also be used. Such couplings may enable
electrical power to be transferred to the data provider 20, and also have the advantage
that the data connection does not require any complex mechanical arrangement and the
30 presence of dirt or grease on the couplings 310, 314 is less likely to inhibit
communication with the data provider 20.
The container 2 may comprise a power provider such as a battery for providing electrical
power to the data provider 20. This may enable the container 2 to be provided with a
range of sensors, including sensors for fluid temperature, pressure and electrical
conductivity. Where the container 2 comprises a filter sensors may be arranged to sense
these parameters of the fluid as the fluid flows into the filter, and after the fluid has flowed
through the filter.
The function of the processors 103, 96 may be provided by any appropriate controller, for
example by analogue and/or digital logic, field programmable gate arrays, FPGA,
application specific integrated circuits, ASIC, a digital signal processor, DSP, or by
software loaded into a programmable general purpose processor.
Aspects of the disclosure provide computer program products, and tangible nontransitory
media storing instructions to program a processor to perform any one or more
of the methods described herein.
The memory 104 is optional. The computer readable identifier may be an optical
identifier, such as a barcode, for example a two-dimensional barcode, or a colour coded
marker, or optical identifier on the container 2. The computer readable identifier may be
provided by a shape or configuration of the container 2. Regardless of how it is provided,
the identifier may be encrypted.
The communication links 97 and/or 98 may be any wired or wireless communication link,
and may comprise an optical link.
Although circulated engine fluid is described as being returned to the fluid container 2 for
recirculation, in the context of the present disclosure, those skilled in the art will
appreciate that circulated engine fluid could be expelled (as it is the case for de-icer)
and/or collected and/or stored in a container coupled to the engine 50 and, when
convenient, emptied from or otherwise removed, e.g., from the vehicle 100.
Other variations and modifications of the apparatus will be apparent to persons of skill in
the art in the context of the present disclosure.
