Description

[0001] TITLE OF INVENTION A SADDLE TYPE VEHICLE

[0002] FIELD OF THE INVENTION

[0003]

[0001] The present invention relates to a saddle type vehicle. More particularly, the present invention relates to disposition of a canister unit in the saddle type vehicle.

[0004] BACKGROUND OF THE INVENTION

[0005]

[0002] Typically, an internal combustion engine (IC engine) of a vehicle utilizes a volatile fuel such as gasoline, diesel and the like as a fuel source. At elevated temperatures, the volatile fuel readily evaporates, thereby increasing the likelihood of releasing emissive fuel vapours out of a fuel tank of the vehicle and potentially causing air pollution. Accordingly, it is known in the art to provide evaporative emission control systems to address this issue. These systems typically incorporate a canister containing a highly adsorbent material (such as activated carbon) with a large surface area. The canister receives the fuel vapours from the fuel tank due to a concentration differential and allows adsorption of the fuel vapours onto the adsorbent material. The canister then stores these adsorbed fuel vapours within its volume until purged. The canister is connected to the engine’s intake manifold through another hose to facilitate the introduction of the adsorbed vapours into the engine for combustion.

[0006]

[0003] However, in the automotive industry, mounting of the canister in the vehicle presents significant challenges. These include ensuring structural integrity of the canister during vibration and field tests while optimizing packaging of the canister within the vehicle's space constraints. Typically, the canister is positioned on the front side of the fuel tank, close to a shock absorber of a suspension assembly of the vehicle. However, such a placement present challenges during development test verification plugs (DVP) and vibration tests. Existing mounting brackets used to mount the canister are made of plastic panels which fail to provide the necessary structural robustness required for reliable operation under dynamic conditions, increasing the risk of failures during testing phases.

[0004] Furthermore, the existing configuration of canister placement leads to critical failures during vibration and road tests. Conventional mounting brackets attached to the fuel tank via spot welding and through other welding techniques frequently fail under the strenuous conditions encountered in testing scenarios. This failure results in detachment of the mounting bracket from the fuel tank, posing significant threats to the structural integrity and functionality of the entire emission control system. Additionally, the integration of a moulded bracket directly onto the fuel tank poses risk of damaging the tank itself during assembly or maintenance.

[0007]

[0005] Moreover, the existing placement of canister necessitates longer hoses, such as a 200 mm hose connecting a purge control valve to the engine’s intake manifold. Longer hoses introduce complexities such as increased bending, squeezing, and potential blockages, which can lead to functional issues and compromise the overall performance of the emission control system. These hoses are critical for managing fuel vapor and must be carefully routed to avoid interference with other components and potential damage during vehicle operation. Further, mounting of canister directly to the fuel tank has proven ineffective, as evidenced by detachment during vibration tests. Moreover, routing these hoses around the canister further impairs packaging challenges, potentially leading to component damage over time. Extensive hose lengths and complex routing not only complicates assembly but also increases manufacturing costs.

[0008]

[0006] In view of the above, there is a need of a solution to overcome at least the above-mentioned disadvantages of the prior arts.

[0029] DETAILED DESCRIPTION OF THE INVENTION

[0030]

[0019] Various features and embodiments of the present invention here will be discernible from the following further description thereof, set out hereunder.

[0031]

[0020] In the context of the present invention, a longitudinal axis refers to a front to rear axis relative to the saddle type vehicle, defining a vehicle longitudinal direction; a lateral axis refers to a side to side, or left to right axis relative to said saddle type vehicle, defining a vehicle lateral direction and a vertical axis refers to a upward to downward axis relative to the saddle type vehicle, defining a vehicle vertical direction.

[0032]

[0021] The present invention generally relates to a saddle type vehicle. More particularly, the present invention relates to disposition of a canister unit in the saddle type vehicle. By positioning the canister unit near a fuel tank and in close proximity to a power unit, the present invention significantly reduces hose lengths, decreases evaporative emissions through permeation thereby enhancing the effectiveness of the evaporative emissions (EVAP) system.

[0033]

[0022] Figure 1A illustrates a left-side view of a frame structure of a saddle type vehicle 100 with a canister unit 108, in accordance with an embodiment of the invention. The term saddle type vehicle has been interchangeably used with term vehicle.

[0034]

[0023] The vehicle 100 comprises a head pipe 102 and a frame assembly 104 extending rearwardly from the head pipe 102 in a vehicle front-rear direction. In an embodiment, the frame assembly 102 comprises a main frame 102a. The head pipe 102 is located at a front side of the main frame 102a and extended in a vehicle upward-downward direction. The head pipe supports a steering shaft (not shown) of the vehicle 100. One or more seat tubes 102b extend rearwardly from the main frame 102a. The one or more seat tubes 102b are adapted to support a seat assembly (not shown) of the vehicle 100. In an embodiment, the main frame 102a is adapted to partially support the seat assembly of the vehicle 100. In an embodiment, the frame assembly 104 is a trellis type frame assembly, and is made of light weight metal alloy tubes joined together in a triangular form to reinforce and support the vehicular components.

[0035]

[0024] Further, the saddle type vehicle 100 includes a power unit 110 and a fuel tank 106 that is supported by the main frame 102a. In a non-limiting example, the power unit 110 is an internal combustion engine. Further, the saddle type vehicle 100 comprises a canister unit 108.

[0036]

[0025] Figure 2 illustrates a front perspective view of a fuel tank and the canister unit, in accordance with the embodiment of the present invention. As shown, the canister unit 108 comprises a canister 108a, a first hose 108b, a purge control valve 114 and a second hose 114a. The canister unit 108 is a vital component to capture and store fuel vapours emitted from a vehicle's fuel tank 106. These vapours contain volatile organic compounds (VOCs) that are harmful to the environment and contribute to air pollution if released directly into the atmosphere. The canister unit 108 plays a crucial role in reducing these emissions by safely containing fuel vapors and later purging the fuel vapors into the engine for combustion, thereby reducing the vehicle's overall environmental impact. In a non-limiting example, the canister unit 108 is cylindrical container. The canister unit 108 is designed to withstand varying temperatures and pressures encountered within the power unit 110 of the vehicle 100. The canister 108a comprises an adsorbent configured to adsorb fuel evaporative gas (otherwise referred to as fuel vapours) from the fuel tank 106. The adsorbent preferably occupies a large surface area within the canister 108a to facilitate effective adsorption of the fuel vapors. In a non-limiting example, the adsorbent is activated charcoal arranged in the form of beds. The adsorbent traps fuel vapors effectively while allowing air to pass through. For example, the fuel vapours generated in the fuel tank are drawn into the canister 108 a. During engine operation, the purge control valve 114 opens to release the stored vapours into an intake manifold of the engine 110. This process allows the vapours to mix with incoming air and be burned off in the combustion chamber, thereby reducing emissions.

[0037]

[0026] In the saddle type vehicle 100, at least a portion of the canister unit 108 being disposed between the head pipe 102 and the fuel tank 106. In an embodiment, the canister unit 108 is configured to define a first portion and a second portion of the canister 108a. The first portion of the canister 108a is disposed between the head pipe 102 and the fuel tank 106. The second portion of the canister 108a is disposed below the fuel tank 106.

[0027] In an embodiment, the canister 108a overlaps with the fuel tank 106 and the power unit 110 when viewed from the top and the first portion of the canister 108 a is the front portion of the power unit 110 and below the fuel tank 106 when viewed from the one side of the vehicle 100. Such disposition of the canister unit 108 below the fuel tank 106 in the present invention provides protection to the canister unit 108 from external disturbances such as rain, sunlight and impact from debris on a road surface. The canister 108a extends longitudinally in the front-rear direction of the vehicle.

[0038]

[0028] Further, the canister 108a is disposed in front of the power unit 110 and below the fuel tank in the vehicle front-rear direction. Such a disposition of the canister unit 108 in proximity to the fuel tank 106 and the power unit 110 in the present invention minimizes the length of hose used thereby reducing the evaporative emission through permeation and improving the cost effectiveness. Moreover, the present invention ensures that the positioning the canister unit 108 does not interfere with the serviceability of adjacent components, such as a cylinder head (not shown) of the engine 110. During maintenance tasks like tappet clearance adjustments and servicing of valve train parts within the cylinder head, there is no requirement to remove the canister 108a thus facilitating easier and more efficient servicing of the engine components without unnecessary disassembly, thereby saving time and effort.

[0039]

[0029] In an embodiment, the canister unit 108 can be at an offset position along a lateral axis (L-L’) of the vehicle 100. In a non-limiting example, the canister 108a is disposed to a right side of a central longitudinal axis (C-C’) of the vehicle. Specifically, the canister 108a can be disposed offset to the right side of the central longitudinal axis (C-C’) of the vehicle. The central longitudinal axis (C-C’) of the vehicle is an imaginary line that runs from the front to the rear direction of the vehicle, dividing it into symmetrical left and right halves.

[0040]

[0030] In another non-limiting example, the canister 108a can be disposed to the left side of the central longitudinal axis (C-C’) of the vehicle. Specifically, the canister 108a is disposed offset to the left side of the central longitudinal axis (C- C’) of the vehicle.

[0031] In another embodiment, the canister 108a can be at a central position along the lateral axis (L-L’) of the vehicle 100. The lateral axis (L-L’) is an imaginary line that is perpendicular to the central longitudinal axis (C-C’) and runs across the width of the vehicle.

[0041]

[0032] Figure IB illustrates a right-side view of a frame structure of a saddle type vehicle with a mounting unit, in accordance with the embodiment of the present invention. As shown, the canister unit 108 is detachably mounted to the head pipe 102 through a mounting unit 112. In a non-limiting example, the canister unit 108 is disposed below the fuel tank 106, behind the head tube 102, and in front of the cylinder head of the engine 110.

[0042]

[0033] Figure 3 illustrates a left-side view of the canister unit and the fuel tank, in accordance with the embodiment of the present invention. Figures 4A and 4B illustrate right-side perspective views of the canister unit and the fuel tank, in accordance with the embodiment of the present invention. Referring to Figure 3 and Figure 4A in conjunction with Figure 2, the canister unit 108 comprises the first hose 108b extending between a first end and a second end. The first end of the first hose 108b is fluidically connected to the fuel tank 106 and the second end of the first hose 108b is connected the canister 108a. In a non-limiting example, the fuel tank 106 in the vehicle 100 accumulates fuel vapours due to factors such as temperature changes and refuelling. These vapours contain volatile organic compounds (VOCs) that contribute to air pollution if released into the atmosphere. A vapor discharge mechanism (not shown) can be provided in the fuel tank 106 to channel out the vapours accumulated and / or generated in the fuel tank 106 from the fuel tank 106 in a controlled manner. The vapor discharge mechanism can direct the fuel vapours towards the canister unit 108 for containment and subsequent processing. The first hose 108b of the canister unit 108 is a conduit for transferring fuel vapours from the vapor discharge mechanism of the fuel tank 106 to the canister 108a. This ensures that all vapours expelled from the fuel tank 106 are efficiently captured and contained within the canister unit 108. By connecting the vapor discharge mechanism directly to the canister unit 108 via the first hose 108b, the present invention prevents the release of the fuel vapours generated in the fuel tank 106 into the environment. This is critical for reducing vehicle emissions and complying with environmental regulations. As fuel vapours enter the canister unit 108 through the first hose 108b, the fuel vapours come in contact with the adsorbent materials such as activated charcoal. These materials have high surface areas capable of trapping and retaining VOCs from the fuel vapours effectively while allowing clean air to pass through.

[0043]

[0034] Further, the canister unit 108 comprises at least one purge control valve (PVC) 114 disposed on a lateral side of the canister 108a. The purge control valve 114 is fluidly coupled to the canister 108a. In an embodiment, the purge control valve 114 can be controlled by an engine control unit (not shown) of the vehicle. For example, during operation, when conditions are appropriate such as engine temperature, speed, and load, the engine control unit commands the purge control valve 114 to open. Opening the valve 114 allows engine vacuum to draw fuel vapours from the canister 108a into the intake manifold (not shown). The PCV 114 is configured to regulate the flow of the fuel vapours from the canister 108a to the intake manifold. This regulation ensures that the power unit receives only the amount of vapours needed for efficient combustion, without affecting engine performance negatively.

[0044]

[0035] Further, the canister unit 108 comprises the second hose 114a. The second hose 114a extends between a first end and a second end. The first end of the second hose 114b is connected to the purge control valve 114 and the second end of the second hose 114b being connected to the intake manifold of the power unit 110. By routing the purged fuel vapours directly to the intake manifold, the second hose 114a ensures that these vapours are drawn into the engine's combustion chamber during normal engine operation. In the engine's combustion chamber, the purged vapours mix with fresh air and are burned off during normal combustion processes. This ensures complete combustion of fuel vapours, minimizing emissions of harmful pollutants into the atmosphere. In the present invention, the canister unit 108 is disposed below the fuel tank 106 optimizing the routing of the first hose 108b (also referred to as vapour hose) close to the engine 110 and the fuel tank 106 resulting in improved purge function. The integration of a rollover valve within a fuel cap of the fuel tank 106, along with the proximity of the purge control valve 114 to the canister unit 108, further enhances the effectiveness of the EVAP system.

[0036] Figure 5 illustrates a left-side perspective view of the canister unit, in accordance with the embodiment of the present invention. Referring to Figure 5, the canister unit 108 is disposed below the fuel tank 106, behind the head tube 102, and in front of the cylinder head of the engine 110. The canister unit 108 is detachably mounted to the head pipe 102 through a mounting unit 112. In an embodiment, a first mounting bracket 102c provided on the head pipe 102 for securely mounting the canister unit 108 onto the head pipe 102.

[0045]

[0037] Figure 6 illustrates an exploded view of the mounting unit being assembled to a front portion of the saddle type vehicle, in accordance with the embodiment of the present invention. Further, referring to Figure 6 in conjunction with Figure 4B, the canister unit 108 being detachably mounted to the head pipe 102 through the mounting unit 112. The mounting unit 112 comprises the first mounting bracket 102c and a second mounting bracket 112c. The first mounting bracket 102c is mounted to the head pipe 102. The second mounting bracket 112c is adapted to be received on the first mounting bracket 102c. The second mounting unit 112 comprises an engaging portion 112b adapted to be engaged with the canister 108a and an opposite face being adapted to affix on a portion of the first mounting bracket 102c provided on the head pipe 102 of the vehicle. The mounting unit 112 includes at least one fastening device 112a to detachably attach the canister unit 108 onto the head pipe 102. In an embodiment, the canister unit 108 is securely mounted using a canister holder 108c. The canister holder 108c includes a slot 108d to receive the engaging portion 112b of the second mounting bracket 112c. In a nonlimiting example, fastening device 112a is a screw and nut arrangement. In an embodiment, the fastening member 112a such as a nut is inserted through a recess 112d provided on the second mounting bracket 112c and holes 102d on the first mounting bracket 102c provided on the head pipe 102 for securely mounting the canister unit 108 onto the head pipe 102. The first mounting bracket 102c provided on a rear portion of the head pipe 102 when viewed from the front-rear direction of the vehicle 100. The first mounting bracket 102c can be affixed to the head pipe 102 through a conventional technique known in the art such as welding, riveting by set of nuts and the like. The first mounting bracket 102c is provided with holes 102d for attaching the second mounting bracket 112c. In a non-limiting example, the mounting bracket 112 are made from strong and lightweight materials such as aluminium alloy or steel. These materials ensure durability and resistance to vibrations and impacts, which are crucial considering the dynamic nature of vehicle operations.

[0046]

[0038] In another embodiment, the mounting unit 112 can be affixed to the frame assembly 104 through a conventional technique known in the art such as welding, riveting by set of nuts and the like and the mounting face of the mounting unit 112 can be adapted to secure the canister unit 108 through a conventional fastening technique. The present invention eliminates mounting of the canister unit 108 onto the fuel tank 106, thereby eliminating the use of brackets on the fuel tank 106 and thus preventing the failure of the fuel tank 106 due to multiple welding.

[0047]

[0039] The claimed invention as disclosed above is not routine, conventional or well understood in the art, as the present invention enable the following solutions to the existing problems in conventional technologies. By positioning the canister near the fuel tank and in close proximity to the power unit, the present invention reduces hose lengths of both the first hose and the second hose. This reduction not only lowers evaporative emissions through permeation but also enhances the costeffectiveness. Shorter hoses also mitigate the risk of hose damage and simplify routing complexities, thereby improving overall system efficiency. Further, the canister in the present invention is placed in a sheltered location that shields it from external disturbances such as water ingress, sunlight exposure and physical damage caused by debris on road. This protective measure ensures the longevity and reliable operation of the canister under various environmental conditions, thereby enhancing system durability and reliability.

[0048]

[0040] The strategic placement of the canister in the present invention does not impede the serviceability of adjacent parts, such as the cylinder head. This ensures that routine maintenance tasks, such as tappet clearance adjustments and valve train servicing, can be performed without the need to remove or relocate the canister, simplifying maintenance procedures and reducing downtime. Additionally, despite the canister proximity to the engine, the canister operates efficiently without being adversely affected by engine-generated heat. A sufficient gap between the cylinder head and the engine, coupled with the canister's heat-resistant materials, ensures optimal performance without compromising its functionality due to excessive heat exposure.

[0049]

[0041] Implementing the present invention results in lower manufacturing costs due to reduced hose lengths and simplified assembly processes. Moreover, the present invention eliminates unnecessary parts and optimizes component layout reducing the overall weight of the vehicle and thus contributing to improved fuel efficiency and performance. In the present invention, the roll-over valve can be integrated with the fuel cap and the purge control valve is positioned close to the canister enhancing the effectiveness of the evaporative emissions (EVAP) system. Such an integration minimizes the length of vapor hose routing, ensuring efficient purging and venting operations without compromising system performance.

[0050]

[0042] Further, the elimination of certain brackets attached to the fuel tank in the present invention reduces potential points of failure and enhances the overall safety of the fuel tank mitigating risks associated with multiple weld points, thereby improving structural integrity and ensuring compliance with rigorous safety standards. Further, the vehicle equipped with the present invention successfully passes vibration tests, validating the robustness and reliability of the mounting system under dynamic operational conditions thereby meeting stringent performance criteria and regulatory requirements.

[0051]

[0043] 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.
