Description:FIELD OF THE INVENTION
[001] The present invention generally relates to a motor vehicle. More particularly, the present invention relates to a mounting assembly for an evaporative emission control system for the motor vehicle.

BACKGROUND OF THE INVENTION
[002] Generally, in conventional vehicles, exhaustive emissions and evaporative emissions are controlled. The evaporative emissions are controlled by employing an evaporative emission control system in the vehicle. The evaporative emission control system includes an evaporated fuel collecting device, for example, a canister, a plurality of connecting tubes, one or more controlling valves such as Roll Over Valve (ROV), one way valve, and the like. The evaporated fuel collecting device is responsible for collecting the fuel vapour generated inside a fuel tank. The collected fuel vapour is then supplied to the canister through the one or more controlling valves. In conventional vehicles, the ROV is provided between the fuel tank and the canister to avoid any unwanted flooding of the canister or fuel vapour build up in the fuel tank due to roll-over of the vehicle.
[003] The ROV is a safety device designed to prevent the leakage of fuel vapour in vehicles, especially those with a higher risk of rolling over or tilting at extreme angles. Conventionally, the ROV is installed in the fuel system, near the fuel tank. The ROV is commonly used in two-wheeled vehicles, three-wheeled vehicles including trikes, All-Terrain vehicles (ATVs), off-road vehicles, and even some small boats. In two-wheeled vehicles, the installation of the ROV with the canister in the fuel system safeguards against the leakage of the fuel vapour in situations of rollovers or extreme tilting. The ROV consists of a valve body and a float mechanism. The valve body of the ROV is responsible for controlling the fuel vapour flow, while the float mechanism senses changes in the orientation of the vehicle.
[004] The float mechanism inside the ROV is designed to respond to the tilting of the vehicle. When the vehicle is in an upright position, the float rests at a specific level, allowing the ROV to remain open. This permits the fuel tank to breathe and vent properly, preventing excessive pressure buildup in the fuel system. However, if the vehicle starts to tilt due to a rollover, the float mechanism is activated. As the vehicle tilts beyond a certain predefined angle, typically around 45 degrees, the float rises closing the ROV, thereby blocking the fuel vapour escape from the fuel tank towards the canister or from the canister towards the fuel tank. Therefore, the ROV effectively isolates the fuel tank from the canister and prevents any vapour build up.
[005] The ROV is significant in preventing fuel vapour build up. In the absence of ROV, as the fuel vapour build up inside the fuel tank is a safety hazard, and fuel vapour build up inside the canister deteriorates the functioning of the canister. Further, the ROV may incorporate electronic sensors or even microprocessors to detect the orientation of the vehicle. The sensors respond quickly to changes in tilt angles, providing better fuel vapour leak prevention during rollovers. In the absence of the ROV, the leakage of the fuel vapour may lead to considerable fire hazard, explosion and adverse environmental implications such as contamination of soil, groundwater, water bodies, and the like. Therefore, the ROV helps in protecting the fire hazards and the environment.
[006] However, there are certain challenges regarding the mounting of the ROV in the fuel system. The ROV of the evaporative emission control system are mounted in the fuel tank in a variety of ways, depending on the type of valve and the motor vehicle. The ROV may be mounted externally to the fuel tank. The ROV may also be attached in a cavity of an inner plate of the fuel tank. In some cases, the brackets may be welded on the fuel tank and the multiple brackets may be used to hold the ROV. Another such arrangement includes a holder adapted to be mounted onto the fuel tank using the mounting means for the mounting of the ROV. The holder includes one or more holding provisions and one or more mount openings. Each of the one or more holding provisions has an opening for holding at least the ROV of the evaporative emission control system in the vehicle.
[007] The mounting provisions of the ROV adds to the overall cost and complexity of the fuel system. The mounting of the ROV itself, along with the necessary components, increases the manufacturing costs, which impacts the overall price of the vehicle. Additionally, the mounting of the ROV requires multiple brackets, further contributing to the increased number of components and thereby increasing the cost of the overall fuel system. The vehicles, such as two-wheeled vehicles, often have limited space available for additional components. Therefore, finding an appropriate location around the fuel tank to mount the ROV, the canister and the other components is challenging.
[008] Further, the ROV can experience wear and tear over time. Regular maintenance and inspection are crucial to ensure that the ROV remains in good working condition. However, maintenance of the ROV requires specialized tools and expertise, which could lead to higher service costs. In the event of a malfunction or failure, repairing or replacing the ROV might also be more intricate compared to standard fuel system components. While mounting the ROV, it is important to consider future maintenance and servicing requirements. The ROV should be placed in a location that allows easy access for inspection, cleaning, or replacement if necessary. It should be readily accessible without requiring excessive disassembly or removal of other components.
[009] Also, the ROV and the canister must be compatible with the specific fuel system of the vehicle. This includes considerations such as fuel tank capacity, fuel line connections, and fuel flow requirements. It is crucial to ensure that the ROV and the canister are designed to handle the fuel type used in the vehicle and can withstand the pressure and temperature variations encountered in the fuel system. Further, two-wheeled vehicles are subject to various vibrations and impacts while in use. The mounting location of the ROV should be chosen to minimize the exposure of the ROV and the canister to potential damage or excessive vibrations. Also, adequate protection and securing mechanisms should be employed to prevent the ROV from dislodging or getting damaged during normal vehicle operation or potential accidents. The mounting location of the ROV should be such so that the ROV is able to prevent the leakage of the fuel vapour.
[010] Moreover, the conventional system faces challenges due to its increased number of parts, leading to higher costs and longer assembly times that demand attention. Furthermore, the abundance of components in the conventional fuel system introduces maintenance complexities, assembly difficulties, and potential points of failure especially for small vehicles such as two wheeled and three wheeled vehicles. The numerous joints associated with the conventional ROV mounting may compromise reliability and leak prevention, posing risks of fuel vapour leakage, necessitating additional maintenance efforts. The current mounting of the ROV and the associated components is inefficient, time-consuming and escalates labour expenses.
[011] Thus, there is a need in the art for a motor vehicle, which addresses at least the aforementioned problems.

[038] Furthermore, in an embodiment, the vehicle 10 comprises a rotary electric machine (not shown). The rotary electric machine is connected to a crankshaft of the internal combustion engine 12. In an embodiment, the rotary electric machine is an ACG machine or magneto that is configured to rotate with the crankshaft and convert rotational energy into electric energy to provide electrical power to vehicle components and charge a battery of the motor vehicle 10.
[039] Figure 3 illustrates a top view of the fuel tank 40, in accordance with an embodiment of the present invention. Figure 4 illustrates a perspective view of an inner part of the fuel tank 40, in accordance with an embodiment of the present invention. As illustrated, the motor vehicle 10 has a fuel vapour collecting device 102. The fuel vapour collecting device 102 is disposed inside the fuel tank 40. The fuel vapour collecting device 102 is configured to absorb and collect the fuel vapours inside the fuel tank 40 during the extreme tilting of the motor vehicle 10, thereby preventing fuel vapour build up inside the fuel tank 40. In an embodiment, the fuel vapour collecting device 102 collects the fuel vapours from the fuel tank 40 and then the collected fuel vapours flow through a pair of connecting tubes 110a, 110b (shown in Figure 6) and then through the pair of connecting tubes 110a, 110b to the fuel vapour retaining device 108 (shown in Figure 6).
[040] In an embodiment, the fuel tank 40 includes a fuel pump 104 and a fuel sensor 106. In an embodiment, the fuel pump 104 is integrated into the fuel tank 40 to deliver pressurized fuel to the engine 12 for efficient combustion. The fuel pump 104 includes an integrated internal fuel filter, which ensures that the fuel is filtered on first level, before exiting the fuel tank 40. In another embodiment, the fuel sensor 106 measures the fuel level inside the fuel tank 40 and provides feedback to the vehicle’s fuel gauge or fuel monitoring system, allowing a rider to monitor the remaining amount of fuel.
[041] Figure 6 illustrates a perspective view of the fuel tank 40, in accordance with an embodiment of the present invention. As illustrated, the motor vehicle 10 includes the fuel vapour retaining device 108. The fuel vapour retaining device 108 is disposed on an under side of the fuel tank 40. The fuel vapour retaining device 108 is in fluid communication with the fuel vapour collecting device 102 (shown in Figure 4). In an embodiment, the fuel vapour retaining device 108 is disposed below a bottom surface of the fuel tank 40 in a motor vehicle top-down direction.
[042] In an embodiment, the fuel vapour retaining device 108 is a sealed storage device filled with adsorbent material such as activated charcoal, carbon pellets, and the like. The fuel vapour retaining device 108 receives the fuel vapour collected by the fuel vapour collecting device 102, and captures and stores the fuel vapour when the motor vehicle 10 is not in the running condition. The fuel vapour retaining device 108 is responsible for storing the fuel vapour that would otherwise be released into the atmosphere, thereby preventing the air pollution. The fuel vapour retaining device 108 is connected to the fuel tank 40 through a network of hoses or pipes. The fuel vapour generated in the fuel tank 40 due to factors such as fuel evaporation or changes in temperature are directed to the fuel vapour retaining device 108 instead of being released directly into the atmosphere. When the motor vehicle 10 is in the running condition, the fuel vapour retaining device 108 purges the collected fuel vapour by allowing them to be drawn into the engine intake manifold. The intake vacuum created by the operation of the engine 12 facilitates the flow of the fuel vapour from the fuel vapour retaining device 108 into the combustion chamber, where they are burned along with the air-fuel mixture during the combustion process. By capturing and purging the fuel vapour, the fuel vapour retaining device 108 helps to reduce the harmful emissions, especially volatile organic compounds (VOCs) that contribute to air pollution. The fuel vapour retaining device 108 ensures that the fuel vapour is effectively recycled and utilized in the combustion process rather than being released into the environment. In an embodiment, a purge valve is disposed between the fuel vapour retaining device 108 and the engine intake manifold. The purge valve is an electronically controlled valve and is configured for regulating the flow of the stored fuel vapour from the fuel vapour retaining device 108 to the combustion chambers for burning during the operation of the engine.
[043] As depicted in Figure 6, the motor vehicle 10 has a pair of connecting tubes 110a, 110b. The pair of connecting tubes 110a, 110b includes a first connecting tube 110a and a second connecting tube 110b. The pair of connecting tubes 110a, 110b is configured for fluidly connecting the fuel vapour retaining device 108 and the fuel vapour collecting device 102. The pair of connecting tubes 110a, 110b are a pathway that connects the fuel vapour collecting device 102 placed inside the fuel tank 40 to the fuel vapour retaining device 108. The pair of connecting tubes 110a, 110b allow the fuel vapour to travel from the fuel tank 40 to the fuel vapour retaining device 108. The pair of connecting tubes 110a, 110b are configured to prevent flow of fuel vapour from the fuel vapour retaining device 108 to the fuel tank 40, and from the fuel tank 40 to the fuel vapour retaining device 108 under certain conditions.
[044] Figure 5A illustrates a top view of an auxiliary component 112 of the motor vehicle 10, in accordance with an embodiment of the present invention. Figure 5B illustrates a side view of the auxiliary component 112 of the motor vehicle 10, in accordance with an embodiment of the present invention. Figure 5C illustrates a front view of the auxiliary component 112 of the motor vehicle 10, in accordance with an embodiment of the present invention. As illustrated, the motor vehicle 10 includes an auxiliary component 112. The auxiliary component 112 is a safety feature in the fuel tank 40. The auxiliary component 112 prevents the leakage of the fuel vapour in the event of a rollover or when the motor vehicle 10 is tilted at extreme angles. The auxiliary component 112 closes the vent of the fuel tank 40 during such situations. The auxiliary component 112 is disposed inside the fuel tank 40. The auxiliary component 112 is configured for restricting the flow of the fuel vapour.
[045] As depicted in Figure 5A, Figure 5B and Figure 5C, the auxiliary component 112 has a first stem portion 112a, a second stem portion 112b, a body 112c and a plurality of intermediate parts 112d. The body 112c includes a float mechanism or a rollover ball that reacts to changes in the orientation of the motor vehicle 10. When the motor vehicle 10 is in an upright condition, the auxiliary component 112 allows the fuel tank to vent properly, maintaining the fuel system's equilibrium. However, when the motor vehicle starts to tilt beyond a certain predetermined angle, typically around 45 degrees, the auxiliary component 112 promptly closes to prevent the fuel vapour from escaping. The first stem portion 112a is configured to be connected to the first connecting tube 110a and the second stem portion 112b is configured to be connected to the second connecting tube 110b. The first stem portion 112a and the second stem portion 112b may or may not be offset of each other. Also, the auxiliary component 112 has a plurality of intermediate parts 112d, the plurality of intermediate parts 112d is elevated than the body 112c of the auxiliary component 112. The plurality of intermediate parts 112d is responsible for connecting the first stem portion 112a and the second stem portion 112b with the body 112c of the auxiliary component 112. In an embodiment of the present invention, the auxiliary component 112 includes a one-way valve, a two-way valve, a canister purge valve, a roll-over valve, a vent control valve and an evaporative canister vent solenoid.
[046] Furthermore, the auxiliary component 112 is provided inside the mounting assembly 114 (shown in Figure 6). The mounting assembly 114 is configured to hold the auxiliary component 112 when the motor vehicle 10 tilts beyond a predetermined angle. In an embodiment, the predetermined angle of the motor vehicle 10 tilt is 45 degrees. In effect, when the vehicle 10 tilts beyond a predetermined angle, the auxiliary component 112 by virtue of being inside the mounting assembly 114, prevents the flow of fuel vapour from the fuel vapour retaining device 108 to the fuel tank 40 thereby preventing fuel vapour buildup in the fuel tank 40. Further, the flow of fuel vapour from the fuel tank 40 to the fuel vapour retaining device 108 is also prevented, thereby preventing the fuel vapour retaining device 108 from being flooded with the fuel vapour.
[047] Figure 7 illustrates a perspective view of the fuel tank 40, in accordance with an embodiment of the present invention. As illustrated in Figure 6 and Figure 7, the motor vehicle 10 includes a mounting assembly 114. The mounting assembly 114 has a first support structure 116 and a second support structure 118. In an embodiment, the first support structure 116 and the second support structure 118 are provided and the conventional mounting brackets for the auxiliary component 112 has been eliminated altogether. This leads to a reliable, efficient and cost-effective system. The first support structure 116 and the second support structure 118 are provided on the external surface 40a of the fuel tank 40. The mounting assembly 114 is configured to receive the auxiliary component 112 between the first support structure 116 and the second support structure 118, thereby holding the auxiliary component 112 in a predefined position when the motor vehicle 10 tilts beyond a predetermined angle. In an embodiment, the predefined position of the auxiliary component 112 refers to a position of the auxiliary component 112 at which the auxiliary component 112 restricts the flow of the fuel vapour, wherein the external surface 40a of the fuel tank 40 is in contact with the body 112c of the auxiliary component 112. Therefore, the predefined position is the position of the auxiliary component 112, wherein the auxiliary component 112 is strongly held inside the mounting assembly 112 during the tilting conditions of the motor vehicle 10.
[048] The mounting assembly 114 is provided on the outer side of the fuel tank 40. Further, the first support structure 116 and the second support structure 118 extend parallelly to each other, in such a manner so as to define a space between them. The space is configured to receive the auxiliary component 112. In an embodiment of the present invention, the first support structure 116 and the second support structure 118 are disposed on an external surface 40a of the fuel tank 40.
[049] As shown in Figure 6 and Figure 7, the auxiliary component 112 is configured for connecting the first connecting tube 110a to the second connecting tube 110. The auxiliary component 112 is further configured for restricting the flow of the fuel vapour inside the pair of connecting tubes 110a, 110b.
[050] Figure 8 illustrates a mounting assembly for the auxiliary component, in accordance with an alternative embodiment of the present invention. In an embodiment, the auxiliary component 112 reacts to the changes in the orientation of the motor vehicle 10, and upon tilting the vehicle 10 on either side, the auxiliary component 112 inside the mounting assembly 114 starts moving accordingly, responding to the change in the orientation of the vehicle. The auxiliary component 112 is made of a metal or coated with metal particles, so that when the auxiliary component 112 comes in contact with the external surface 40a, the auxiliary component 112 is strongly held by the external surface 40a in a predefined position because of the magnetic properties of the external surface 40a. The elevated surface 40a of the fuel tank 40 ensures that there is a contact between the body 112c of the auxiliary component 112 and the magnetic surface 120.
[051] Further, the first support structure 116 and the second supporting structure 118 ensures that the auxiliary component 112 is placed in a predefined position and the position is not disturbed due to the tilting or the vibration of the motor vehicle 10. Furthermore, the first support structure 116 and the second supporting structure 118 ensures that the auxiliary component 112 is easily mounted during the assembly of the motor vehicle 10. This is because the first support structure 116 and the second supporting structure 118 indicates the accurate positioning of the auxiliary component 112. Once the auxiliary component 112 is inserted between the first support structure 116 and the second supporting structure 118, then the first support structure 116, the second supporting structure 118, the magnetic surface along with the raised magnetic surface ensures that the auxiliary component 112 is strongly held within the desired position.
[052] In an embodiment, the mounting assembly 114 of the present invention is also used to mount the ROV and other auxiliary components of the evaporative emission control system.

[055] In an embodiment, the connecting tubes 110a, 110b are preformed and made of multiple layers of resin. In yet another embodiment of the present invention, the connecting tubes 110a, 110b are made vibration proof, by adding the support structures 116, 118 within the fuel tank 40 to hold the connecting tubes 110a, 110b in position.
[056] Advantageously, the present invention provides for a motor vehicle with connecting tubes for connecting the fuel vapour collecting device to the fuel vapour retaining device through the auxiliary component. The present system eliminates the need of the mounting brackets required to mount the auxiliary component. The evaporative emission control system as disclosed in the present invention is cost-effective due to lesser number of parts, thereby the overall assembly time of the evaporative emission control system is reduced. The overall system becomes more robust against fuel vapour leakage because of the reduced number of joints involved, thereby it is ensured that the present system is reliable and efficient.
[057] The overall complexity of the present system is reduced due to the lesser number of parts. The available space within the fuel system in the vehicle is efficiently utilised due to the reduced number of the components. Since the mounting brackets for the auxiliary component is excluded altogether in the present system, the overall maintenance costs are also reduced considerably. Therefore, the mounting assembly as disclosed in the present invention is cost-effective, reliable and efficient as compared to the conventional mounting brackets for the auxiliary component.
[058] The mounting assembly is further placed close to the fuel vapour retaining device, thereby the connecting tubes are directly connected with the fuel vapour retaining device, and hence utilising a shorter connecting tube in the present system. Due to the reduced length of the connecting tube, the chances of damage of the connecting tubes from the vibration are also minimized.
[059] While the present invention has been described with respect to certain embodiments, it will be apparent to those skilled in the art that various changes and modification may be made without departing from the scope of the invention as defined in the following claims.
