TECHNICAL FIELD
[001] The subject matter in general relates to supplying urea water in an
automobile. More particularly, but not exclusively, the subject matter relates to providing a single system that that facilitates the urea water delivery and venting in the automobile.
BACKGROUND
[002] Background description includes information that may be useful in
understanding the present subject matter. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed subject matter, or that any publication specifically or implicitly referenced is prior art.
[003] For in cabin urea tank application, both urea water delivery and venting
line has to be layout from inside cabin to under body. In such a case, sealing of the inside cabin is of prime importance. Since both the delivery and venting line are mounted on the urea tank, both the tubes will have dynamic loads based on the tank vibrations in vehicle and urea water flow pulsation.
[004] Conventionally, a rubber grommet is used to overcome the above stated
problem. The rubber grommet has to ensure sealing with the body and also in the areas where both the pipes are passing from inside cabin to outside.
[005] In such cases, the sealing and assembly of both the pipes are a
challenging task.

[0022] Referring to FIG. 1 disclosed is a system 100 for facilitating urea water delivery and venting in a vehicle. The system 100 comprises a plate 102, a venting channel 104 and a urea delivery channel 106.
[0023] In an embodiment, the plate 102 is circular in shape or in a shape that corresponds to the shape of the part to which the plate 102 is affixed to.
[0024] In an embodiment, the venting channel 104 and the urea delivery channel 106 are configured to extend transversely through the plate 102.
[0025] In an embodiment, the venting channel 104 extends transversely from a top surface of the plate 102 and extends transversely from a bottom surface of the plate 102 in a direction opposite to the direction of extension from the top surface, such that the extensions of the venting channel 104 from the top surface and the bottom surface form a single channel for fluid to pass through. As an exemplary embodiment, the fluid passing through the venting channel 104 is gas accumulated in urea tank 302 (shown in FIG. 3).
[0026] In an embodiment, the urea delivery channel 106 extends transversely from a top surface of the plate 102 and extends transversely from a bottom surface of the plate 102 in a direction opposite to the direction of extension from the top

surface, such that the extensions of the urea delivery channel 106 from the top surface and the bottom surface form a single channel for fluid to pass through. As an exemplary embodiment, the fluid passing through the urea delivery channel 106 is urea water from the urea tank 302 (shown in FIG. 3).
[0027] In an embodiment, a rubber seal 120 is configured to surround the plate 102.
[0028] In an embodiment, a plate extension 108 protrudes transversely from the plate 102 in one particular direction. A plurality of snap fit structures 110 are attached on outer surface of the plate extension 108.
[0029] In an embodiment, the urea delivery channel 106 is divided into first channel 114 and second channel 116. The first channel 114 and the second channel 116 are configured to be transverse to each other, such that the first channel 114 extends transverse from the top surface of the plate 102 and the second channel 116 extends transversely from the first channel 114.
[0030] In an embodiment, an extended channel 118 is defined at the intersection of the first channel 114 and the second channel 116. The second channel 116 extends from the first channel 114 at an intermediate position such that the extended channel 118 is defined in the first channel 114.
[0031] In an embodiment, the extended channel 118 provides a safety measure for icing of the urea water in colder conditions. As an exemplary embodiment, the urea water expands by 7% in volume under frozen conditions and the extended channel 118 is configured to accommodate the expanding volume of the urea.
[0032] In an embodiment, the venting channel 104 comprises a duct cap 112.
[0033] Referring to FIGs. 2 and 3, the plate 102 is configured to be affixed to a floor panel 200 of the vehicle. The plate 102 is attached to the floor panel using the snap fit structures 110 provided on the plate extension 108.

[0034] In an embodiment, an anti-rotation feature is provided in the plate extension 108 so as to restrict the rotation of the plate 102 with respect to the floor panel 200.
[0035] In an embodiment, the floor panel 200 of the vehicle defines a cut-out to receive the plate 102 and therefore the pate 102 defines the shape of the cut-out.
[0036] In an embodiment, the rubber seal 120 surrounding the plate 102 is provided as an insulation between the plate 102 and the floor panel 200, whereby the rubber seal 120 absorbs any undue vibrations creeping through the venting channel 104 and the urea delivery channel 106.
[0037] The floor panel 200 divides the space into first space 202 and second space 204. The first space 202 is the space within the vehicle and the second space 204 is below the floor panel of the vehicle, wherein exhaust system of the vehicle is affixed. In other words, the second space 204 is the underbody of the vehicle.
[0038] In an exemplary embodiment, the first space 202 is the boot space of the vehicle, wherein the urea tank 302 is located.
[0039] In an embodiment, the venting channel 104 and the urea delivery channel 106 extend from the first space 202 to the second space 204.
[0040] In an embodiment, the urea delivery channel 106 is divided into the first channel 114 and the second channel 116 in the first space 204.
[0041] In an embodiment, a venting pipe 206 is connected to the venting channel 104 in the first space 204. The other end of the venting pipe 206 is in contact with the urea tank 302. The venting pipe vents out the pressurised gas built in the urea tank 302. The venting channel 104 comprises a dust cap 112 in the second space 204. The dust cap 112 prevents the entry of the foreign elements into the venting channel 104.
[0042] In an embodiment, the urea delivery channel 106 is connected to the

urea tank 302 in the first space 202 using a urea delivery pipe 208. The urea delivery channel 106 is connected to an exhaust in the second space 204 using an exhaust urea pipe 210.
[0043] In an embodiment, the urea delivery pipe 208 is specifically in contact with the second channel 116 of the urea delivery pipe. The extension of the venting pipe 206 and the urea delivery pipe 208 in perpendicular directions help in avoiding the stress accumulation in the system 100. The stress may be accumulated during the engagement and disengagement process of the venting pipe 206 and the urea delivery pipe 208 to the system 100. With the extension of the venting pipe 206 and the urea delivery pipe 208 in perpendicular directions, the stress accumulated in the system 100 due to the engagement and disengagement process of the venting pipe 206 and the urea delivery pipe 208 to the system 100 is cancelled out.
[0044] In an embodiment, the plate 102, the venting channel 104 and the urea delivery channel 106 form a single molded unit.
[0045] In an embodiment, the plate 102, the venting channel 104 along with the dust cap 112 and the urea delivery channel 106 form a single molded unit.
[0046] The single molded structure of the system 100 ensures that there is no chances of leakage in the urea water delivery and venting layout from the inside cabin to the underbody.
