APPLICANT:

TVS MOTOR COMPANY LIMITED, an Indian Company at: “Chaitanya”, No.12 Khader Nawaz Khan Road, Nungambakkam, Chennai 600 006.

The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
[0001] The present subject matter relates generally to a fuel tank assembly, an evaporative emission control system and a mounting member for one or more components of an evaporative emission control assembly of a vehicle. More particularly but not exclusively, the present subject matter relates to a fuel tank assembly, an evaporative emission control system and a mounting member for one or more components of an evaporative emission control assembly of a vehicle.

BACKGROUND
[0002] The evaporative emission control system, especially in a vehicle, is designed to capture and control the fuel vapors that are formed in the fuel system. This is also true for engines of two and three wheeled vehicles. The Evaporative Emission Control System is crucial for reducing harmful emissions and preventing the release of volatile organic compounds (VOCs) and hydrocarbons into the atmosphere. Further, the evaporative emission control system reduces the wastage of the fuel thereby increasing the fuel efficiency and mileage.
[0003] The key components of the evaporative emission control system are a fuel tank, an evaporated fuel collecting device, connecting tubes, a roll-over valve, an evaporated fuel retaining device, a fuel level sensor, and a fuel pump. The vehicle stores its fuel in the fuel tank. The fuel tank is a sealed container, which receives and stores fuel for the vehicle. However, some fuel vapors can still escape through the venting system of the fuel tank, due to variation in temperature and fuel expansion. When the vehicle is not in running condition or the engine is off, the fuel inside the fuel tank can evaporate thereby forming fuel vapors. These vapors rise and are collected by the evaporated fuel collecting device. Further, the fuel vapors are transmitted to the evaporated fuel retaining device, through the connecting tubes, where the fuel vapors are stored temporarily. The purpose of the evaporated fuel retaining device is to prevent the release of harmful fuel vapors into the atmosphere. Commonly known evaporative fuel retaining devices are cannisters installed on two wheeled vehicles having capability to retain fuel vapor. By capturing and collecting the fuel vapors, the evaporated fuel collecting device plays a critical role in reducing evaporative emissions from the vehicle. The roll-over valve is provided between the fuel tank and the evaporative fuel retaining device in order to prevent any unwanted flooding of the evaporated retaining device due to the roll-over of the vehicle. The roll-over valve is a critical safety device designed to prevent fuel leakage in vehicles, especially vehicles with a higher risk of rolling over or tilting at extreme angles like in two-wheeled vehicles, all-terrain vehicles (ATVs), off-road vehicles, and even some small boats. Without the roll-over valve, the fuel could spill out during rollovers or extreme tilting, leading to a considerable fire hazard. The leaked fuel might come into contact with hot engine components, sparks, or open flames, creating the risk of fire or even an explosion. Further, the leaked fuel might contaminate soil, groundwater, or nearby water bodies, causing environmental pollution and potential harm to ecosystems.
[0004] In conventional vehicles, the fuel tank is modified in order to form a pocket for attaching one or more components of the evaporative emission control system. This approach may not be always feasible for a fuel tank of any other vehicle as it requires costly changes in the design of the fuel tank of the vehicle. The external mounting of the one or more components of the evaporative emission control system is typically done on larger vehicles, such as trucks and Sport utility vehicles (SUVs). This approach is also not suitable for small vehicles such as two wheeled vehicles because of the space constraint. The utilization of multiple brackets or holders for the mounting of the one or more components of the evaporative emission control system increases the part-count thereby increasing the cost of the overall fuel system. This can also be more complex and time-consuming to set up as it requires precise alignment of multiple brackets or holders. The incorrect installation of the one or more components of the evaporative emission control system may result in improper working and it may even cause fuel vapor leakage. Due to the usage of multiple brackets or holders, the chances of brackets getting loose or damaged are more because of the involvement of multiple joints. If the mounting bracket is loose or damaged, the valve may not be able to work properly in the event of a rollover. Also, the one or more components of the evaporative emission control system are more likely to fall or move if not secured properly. This can be a safety hazard, especially if the one or more components of the evaporative emission control system are heavy or fragile.
[0005] Two-wheeled vehicles often have limited space available for additional components. Finding an appropriate location within the fuel tank to mount the one or more components of the evaporative emission control system can be challenging. It is crucial to consider the available space and ensure that the brackets or holders, used for mounting, do not interfere with other components or systems. The complex mounting of the one or more components of the evaporative emission control system within the fuel tank, might require specialized tools and expertise for maintenance and servicing. This could lead to higher service costs.
[0006] The complex mounting mechanism, used in conventional vehicle, makes the one or more components of the evaporative emission control system inaccessible during inspection, servicing, repairing, cleaning, or replacement. It requires excessive disassembly or removal of other components due to the unavailability of proper clearance. The vehicles, particularly, two-wheeled vehicles are subjected to vibrations and impacts while in use. Modern vehicles’ designers and manufacturers also have an increasing pressure to compactly package various components to save space, weight for better packaging and fuel efficiency. This necessitates resilient and durable securing mechanisms in order to prevent the one or more components from dislodging or getting damaged during normal vehicle operation or in the event of excessive tilting and potential accidents. Further, in conventional vehicles, the placement of the one or more components of the evaporative emission control system does not allow an efficient operation and simple routing of the fuel lines and the vent hoses.
[0007] To overcome the above-mentioned problems, the disclosed invention provides a more efficient and cost-effective mounting arrangement of the one or more components of the evaporative emission control system. The disclosed invention eliminates the need for extra components without compromising the functioning of the one or more components within the evaporative emission control system of the vehicle. Due to the elimination of multiple parts, the overall fuel system becomes less expensive and overall time needed for assembly, inspection, cleaning, or replacement is reduced.

[0049] The embodiments of the present invention will now be described in detail with reference to an embodiment of a mounting member (200) for one or more components (101) of an evaporative emission control system of a vehicle (100), along with the accompanying drawings. However, the disclosed invention is not limited to the present embodiments.
[0050] The embodiments shown in Figure 1a, and Figure 1b are taken together for discussion. Figure 1a illustrates a side view of a mounting member (200) for one or more components (101) of an evaporative emission control system of a vehicle (100). Figure 1b illustrates a side view of one of the one or more components (101) of the evaporative emission control system.
[0051] The mounting member (200) comprises a linear portion (201) and an arcuate portion (202). The linear portion (201) is attached to a predefined location on the vehicle (100) through a first terminal (201a) of the linear portion (201). The arcuate portion (202) is connected to a second terminal (201b) of the linear portion (201). The arcuate portion (202) receives a predefined portion of the one or more components (101) in a plurality of alternative mounting arrangements. A profile of the arcuate portion (202) conforms with a profile of a lateral surface of the predefined portion of the one or more components (101). in one embodiment, the predefined portion of the one or more components (101) comprises a plurality of arms (101a, 101b). The plurality of arms (101a, 101b) comprising a first arm (101a) and a second arm (101b).
[0052] In a preferred embodiment of the disclosed invention, the mounting member (200) is made up of a material including, but not limited to, metals, resin, rubber and plastic. A length of the mounting member (200) lies in the range of 1 cm to 10 cm. A width of the mounting member (200) lies in the range of 0.2 cm to 4 cm.
[0053] In another preferred embodiment, the one or more components (101) are one or more rollover valve. However, the present invention can also be worked with other components of the fuel system of the vehicle (100). Thus, the one or more components (101) can also include, but not limited to, rollover valve, fuel level sensor (106, shown in Figure 2a), fuel pump (107, shown in Figure 2a) and canister.
[0054] The one or more rollover valve is configured to prevent a spillage of a liquid fuel when the vehicle (100) is tilted at an angle. The one or more rollover valve comprises a valve body, and a float mechanism (rollover ball). The valve body is responsible for controlling the fuel flow, while the float mechanism senses changes in the orientation of the vehicle (100). The float mechanism responds to the shifts in an angle of the vehicle (100). When the vehicle (100) is in an upright position, the float rests at a specific level, allowing the valve to remain open. This permits the fuel tank (105, shown in Figure 2a) to breathe and vent properly, preventing excessive pressure buildup in the fuel system. However, if the vehicle (100) starts to tilt due to a rollover, the float mechanism is activated. As the vehicle (100) tilts beyond a certain angle threshold, typically around 45 degrees, the float rises, closing the one or more rollover valve. Therefore, the spillover or any potential leakage of the liquid fuel from the tank is effectively prevented.
[0055] The mounting member (200) can also be used for mounting the fuel level sensor (106). The fuel level sensor (106) measures the fuel level inside the fuel tank (105) and provides feedback to the vehicle's fuel gauge or fuel monitoring system. Thus, the fuel level sensor (106) allows the rider to monitor the amount of liquid fuel remaining in the fuel tank (105).
[0056] Further, mounting member (200) can be used for mounting the fuel pump (107). The fuel pump (107), integrated into the fuel tank assembly, delivers pressurized liquid fuel to the engine for efficient combustion. The fuel pump (107) includes an integrated internal fuel filter. The integrated internal fuel filter ensures that the liquid fuel is filtered on first level, before exiting the fuel tank (105).
[0057] The embodiments shown in Figure 2a, and Figure 2b are taken together for discussion. Figure 2a illustrates a side perspective view of a fuel tank assembly and an evaporative emission control system for a vehicle (100). Figure 2b illustrates a bottom view of the fuel tank assembly and the evaporative emission control system for the vehicle (100).
[0058] The evaporative emission control system prevents fuel vapor in a fuel tank (105) from escaping into an atmosphere. In this embodiment, the evaporative emission control system comprises an evaporated fuel collecting device (102), one or more valves (101), at least one mounting member (200), and an evaporated fuel retaining device (104). The evaporated fuel collecting device (102) collects the fuel vapour from the fuel tank (105). The one or more valves (101) connects to the evaporated fuel collecting device (102) in order to receive the fuel vapor and a liquid fuel spilled over from the fuel tank (105) upon tilting of the vehicle (100). The one or more valves (101) comprises a plurality of arms (101a, 101b). The at least one mounting member (200) mounts the one or more valves (101) in a plurality of mounting arrangements using the plurality of arms (101a, 101b). The at least one mounting member (200) comprises a linear portion (201), and an arcuate portion (202). The linear portion (201) is attached to the one or more predefined location on the fuel tank (105) through a first terminal (201a) of the linear portion (201). The arcuate portion (202) is connected to a second terminal (201b) of the linear portion (201). The arcuate portion (202) receives one or more of the plurality of arms (101, 101b) of the one or more valves (101) in a plurality of alternative mounting arrangements. A profile of the arcuate portion (202) conforms with a profile of a lateral surface of the one or more of the plurality of arms (101a, 101b) of the one or more valves (101). The evaporated fuel retaining device (104) receives the fuel vapor and a condensed fuel from the one or more valves (101).
[0059] In a preferred embodiment, the evaporated fuel retaining device (104) is a cannister. The canister is a key component of the fuel system of the vehicle (100). The canister is a container filled with adsorbent material. The adsorbent material includes, but not limited to, activated charcoal and carbon pellets. The adsorbent material, present in canister, adsorbs the fuel vapor captured by the evaporated fuel collecting device (102). The adsorbent material also adsorbs the condensed fuel formed due to cooling of fuel vapors while moving from the evaporated fuel collecting device (102) to the canister through the the one or more valves (101). When the engine is running, the canister purges the adsorbed fuel vapors. Thus, allowing the fuel vapors to be drawn into the engine intake manifold. The intake vacuum created by the engine's operation facilitates the flow of the fuel vapors from the canister into the combustion chamber, where they are burned along with the air-fuel mixture during the combustion process. By retaining and purging fuel vapors, the canister not only helps to reduce harmful emissions but also ensures that the fuel vapors are effectively recycled.
[0060] Yet another embodiment of the present invention, as shown in Figures 2a and 2b, a fuel tank assembly for a vehicle (100) is disclosed. The fuel tank assembly comprises the fuel tank (105), and the evaporative emission control system. The fuel tank (105) receives and stores the fuel for the vehicle (100). The evaporative emission control system prevents fuel vapor in the fuel tank (105) from escaping into the atmosphere. The evaporative emission control system comprises the evaporated fuel collecting device (102), one or more valves (101), the at least one mounting member (200), and the evaporated fuel retaining device (104). The evaporated fuel collecting device (102) collects the evaporated fuel vapour from the fuel tank (105). The one or more valves (101) connects to the fuel collecting device (102) in order to receive the fuel vapor and a liquid fuel spilled over from the fuel tank (105) upon tilting of the vehicle (100). The one or more valves (101) comprises a plurality of arms (101a, 101b). The at least one mounting member (200) mounts the one or more valves (101) in a plurality of mounting arrangements using the plurality of arms (101a, 101b) on one or more predefined locations on the fuel tank (105). The at least one mounting member (200) comprises a linear portion (201), and an arcuate portion (202). The linear portion (201) is attached to the one or more predefined location on the fuel tank (105) through a first terminal (201a) of the linear portion (201). The arcuate portion (202) is connected to a second terminal (201b) of the linear portion (201). The arcuate portion (202) receives one or more of the plurality of arms (101, 101b) of the one or more valves (101) in a plurality of alternative mounting arrangements. A profile of the arcuate portion (202) conforms with a profile of a lateral surface of the one or more of the plurality of arms (101a, 101b) of the one or more valves (101). The evaporated fuel retaining device (104) receives the fuel vapor and a condensed fuel from the one or more valves (101).
[0061] In a preferred embodiment, the predefined location for attaching the first terminal (201a) of linear portion (201) of the mounting member (200) is in a proximity of the one or more components (101). As per another embodiment, the predefined location is an underside of a fuel tank (105) of the vehicle (100), in a proximity of the one or more components (101).
[0062] In a preferred embodiment, the predefined portion of the one or more valves (101) comprise a first arm (101a) and a second arm (101b). The at least one mounting member (200) for the first arm (101a) is positioned offset to at least one mounting member (200) for the second arm (101b).
[0063] The first arm (101a) connects with an evaporated fuel collecting device (102) through a first duct (103a). The second arm (101b) connects to an evaporated fuel retaining device (104) through second duct (103b). The one or more components (101) is disposed in a proximity of the evaporated fuel collecting device (102) in order to reduce a length of the first duct (103a). The placement of the one or more components (101) in proximity to each other allows the efficient operation, simple routing and efficient space utilization.
[0064] The one of the plurality of arms (101a, 101b) receives one of the first duct (103a) and the second duct (103b) such that the one of the plurality of arms (101a, 101b) covers one of the first duct (103a) and the second duct (103b) being received. Therefore, the arcuate portion (202) directly receives one of the plurality of arms (101a, 101b). In an alternate embodiment, the one of the plurality of arms (101a, 101b) is received by at least a portion of one of the first duct (103a) and the second duct (103b). The one of the plurality of arms (101a, 101b) gets covered by one of the first duct (103a) and the second duct (103b). Therefore, the arcuate portion (202) indirectly receives one of the plurality of arms (101a, 101b). In a preferred embodiment, the first duct (103a) and the second duct (103b) are preformed. The first duct (103a) and the second duct (103b) are made up of multiple layers of resin.
[0065] The first terminal (201a) of the linear portion (201) is fixedly attached to the predefined location of the vehicle (100) by employing various fabrication processes like welding, brazing, crimping and soldering. In an alternate embodiment, the first terminal (201a) of the linear portion (201) is detachably attached to the predefined location of the vehicle (100). The detachable attachment can be achieved by using fasteners. The fasteners, includes but not limited to clips, latches, screws, nuts and bolts.
[0066] The predefined location for attaching the first terminal (201a) of linear portion (201) of the mounting member (200) is an underside of a fuel tank (105). This configuration allows the mounting of the one or more components (101) on the outer surface of the bottom of the fuel tank (105). Therefore, the one or more components (101) is secured from unnecessary vibration or accidental impacts. Further, it protects the one or more components (101) from falling. Thus, eliminating any safety hazard, especially if the one or more components (101) are heavy or fragile.
[0067] The embodiments shown in Figure 3a, and Figure 3b are taken together for discussion. Figure 3a illustrates a side perspective view of a first mounting arrangement. Figure 3b illustrates a side perspective view of a plurality of mounting member (200) in the first mounting arrangement.
[0068] In the first mounting arrangement, one of the plurality of arms (101a, 101b) is mounted using at least one mounting member (200). The profile of the arcuate portion (202) of the at least one mounting member (200) circumscribes more than a half of the profile of a lateral surface of one of the plurality of arms (101a, 101b). The profile of a lateral surface of one of the plurality of arms (101a, 101b) is in the shape of a complete hoop. However, the profile of the arcuate portion (202) is in the shape of partial-hoop. Thus, the arcuate portion (202) covers more than the half of the complete hoop of the lateral surface of one of the plurality of arms (101a, 101b) instead of covering it completely. The arcuate portion (202), being a partially formed hoop, is provided with a slot (205). The slot (205) allows the one of the plurality of arms (101a, 101b) to easily slide into the arcuate portion (202). The slot (205) formed is smaller than the arcuate portion (202) thereby preventing one of the plurality of arms (101a, 101b) from dislocating due to vibrations, extreme tilting or accidental impact. Further, this ensures that one of the plurality of arms (101a, 101b) can only be removed upon application of manual force in a certain manner.
[0069] In the Figure 3a, one mounting member (200) is used for the first arm (101a) and one mounting member (200) is used for the second arm (101b). The mounting member (200) used for the first arm (101a) is positioned offset and parallel to the mounting member (200) used for the second arm (101b).
[0070] The embodiments shown in Figure 4a, and Figure 4b are taken together for discussion. Figure 4a illustrates a side perspective view of a second mounting arrangement. Figure 4b illustrates a side view of a first mounting member (200a) and a second mounting member (200b) in the second mounting arrangement.
[0071] In the second mounting arrangement, one of the plurality of arms (101a, 101b) is mounted using at least one pair of mounting members (200a, 200b). The at least one pair of mounting members (200a, 200b) comprises a first mounting member (200a) and a second mounting member (200b). The first mounting member (200a) receives one of the plurality of arms (101a, 101b) from a first side of the one of the plurality of arms (101a, 101b) through a first arcuate portion (202a) of the first mounting member (200a). The second mounting member (200b) receives the one of the plurality of arms (101a, 101b) from a second side of the one of the plurality of arms (101a, 101b) through a second arcuate portion (202b) of the second mounting member (200b). The first side is opposite to the second side.
[0072] The first arcuate portion (202a) of the first mounting member (200a) aligns with the second arcuate portion (202b) of the second mounting member (200b) in order to form a circle. The circle accommodates at least one portion of the one of the plurality of arms (101a, 101b). A size of the gap (203) can be adjusted by displacing the first arcuate portion (202a) of the first mounting member (200a) in a direction opposite to the second arcuate portion (202b) of the second mounting member (200b). The gap (203) with adjustable size allows easy sliding of one of the plurality of arms (101a, 101b) into the circle. Once the one of the plurality of arms (101a, 101b) is accommodated in the circle, the size of the gap (203) is reduced again. This ensures that the one of the plurality of arms (101a, 101b) can only be removed upon application of manual force in a certain manner. Further, it hinders the dislodging of the one of the plurality of arms (101a, 101b) due to vibrations, extreme tilting or accidental impact.
[0073] In the Figure 4a, one first mounting member (200a) and one second mounting member (200b) are used for the first arm (101a). Similarly, one first mounting member (200a) and one second mounting member (200b) are used for the second arm (101b). The first mounting member (200a) and the second mounting member (200b) used for the first arm (101a) are positioned offset and parallel to the first mounting member (200a) and the second mounting member (200b) used for the second arm (101b).
[0074] The embodiments shown in Figure 5a, and Figure 5b are taken together for discussion. Figure 5a illustrates a side perspective view of a third mounting arrangement. Figure 5b illustrates a side view of a mounting member (200) and a shaft member (204) in the third mounting arrangement.
[0075] In the third mounting arrangement, one of the plurality of arms (101a, 101b) is mounted using at least one mounting member (200) along with at least one shaft member (204). The at least one mounting member (200) receives the one of the plurality of arms (101a, 101b) from a first side of the one of the plurality of arms (101a, 101b). The at least one shaft member (204) arrests a movement of the one of the plurality of arms (101a, 101b) from a second side of the one of the plurality of arms (101a, 101b). The first side is opposite to the second side.
[0076] There is a pre-defined gap between the at least one mounting member (200) and the at least one shaft member (204). A size of the pre-defined gap can be adjusted by moving either of the at least one mounting member (200) and the at least one shaft member (204) in a direction. The direction is opposite to either of the at least one mounting member (200) and the at least one shaft member (204) which remain still. The pre-defined gap, with adjustable size, allows easy sliding of one of the plurality of arms (101a, 101b) into the arcuate portion (202) of the at least one mounting member (200). This also ensures that the one of the plurality of arms (101a, 101b) can only be removed upon application of manual force in a certain manner. Further, it hinders the dislodging of the one of the plurality of arms (101a, 101b) due to vibrations, extreme tilting or accidental impact.
[0077] In the present embodiment, as shown in the Figure 5a, one mounting member (200) and one shaft member (204) are used for the first arm (101a). Similarly, one mounting member (200) and one shaft member (204) are used for the second arm (101b). The mounting member (200) and the shaft member (204) used for the first arm (101a) is offset and parallel to the mounting member (200) and the shaft member (204) used for the second arm (101b).
[0078] The embodiments shown in Figure 6a, and Figure 6b are taken together for discussion. Figure 6a illustrates a side perspective view of a fourth mounting arrangement. Figure 6b illustrates a side perspective view of a plurality of mounting member in the fourth mounting arrangement.
[0079] In fourth mounting arrangement, the plurality of arms (101a, 101b) comprises a first arm (101a) and a second arm (101b). The first arm (101a) and the second arm (101b) are mounted using at least one mounting member (200) each. The at least one mounting member (200) for the first arm (101a) is positioned parallelly offset to the at least one mounting member (200) for the second arm (101b). The arcuate portion (202) of the at least one mounting member (200) for the first arm (101a) and the arcuate portion (202) of the at least one mounting member (200) for the second arm (101b) are aligned to face opposite directions.
[0080] In a preferred embodiment, the arcuate portion (202) of the at least one mounting member (200) for the first arm (101a) is aligned to face the arcuate portion (202) of the at least one mounting member (200) for the second arm (101b).
[0081] The embodiments of the disclosed invention are not limited to first mounting arrangement, second mounting arrangement and third mounting arrangement. The mounting member (200) can be used in different mounting arrangements, alternatively or in combination with each other. The mounting member (200) allows a mounting of one or more components (101) without carrying out costly modifications in the design of the fuel tank (105). The mounting member (200) allows effective space utilization thereby making it suitable for two wheeled vehicles also. The use of mounting member (200) for mounting of one or more components (101) reduces the part-count as the requirement of multiple brackets or holders is effectively eliminated. The mounting of one or more components (101) using the mounting member (200) does not involve multiple joints. Therefore, the chances of the mounting member (200) getting loose or damaged are less. The placement of the one or more components (101) reduces the size of duct required for routing and also prevents the one or more components (101) from falling and getting damaged. The mounting of one or more components (101) using the mounting member (200) proper clearance. Therefore, assembly, inspection, cleaning, servicing, maintenance or replacement becomes easy. Further, the requirement for specialized tools and expertise for maintenance and servicing of the one or more components (101) is also eliminated. The mounting of one or more components (101) using the mounting member (200) is resilient and durable. Thus, prevents the one or more components (101) from dislodging or getting damaged during normal vehicle operation or in the event of excessive tilting and potential accidents.
