Description

TITLE OF INVENTION:A FUEL SYSTEM OF A VEHICLE AND A METHOD THEREOFTECHNICAL FIELD

[0001] The present invention relates to a fuel system of a vehicle and its installation and method thereof. Present invention also relates to a vehicle having said fuel system.BACKGROUND

[0002] In recent years, the push towards eco-friendly transportation solutions has driven significant interest in alternative fuel sources such as gaseous fuels including but not limited to compressed natural gas (CNG) and liquified petroleum gas (LPG). The gaseous fuels offer lower emissions and reduced costs compared to petrol or diesel, making them attractive options for both consumers and manufacturers alike. However, integrating gaseous fuel systems into vehicles, particularly compact two- wheelers, presents a formidable challenge due to their unique space constraints and layout considerations. This problem becomes more complicated if a liquid fuel system needs to be incorporated in addition to the gaseous fuel system.

[0003] Conventionally, in a two-wheeled vehicle, the gaseous fuel tanks are installed at a rear panel, positioned between a front tyre of the two-wheeler and a driver footrest of the two-wheeler. This prevents the user to carry any item within the driver footrest as the area for mounting items is reduced. While accommodating the gaseous fuel tanks, this placement introduces several drawbacks that affect both vehicle performance and user experience. Firstly, it reduces leg space, compromising driver comfort and maneuverability and secondly, if the gaseous fuel tanks are placed in a rear portion of the two-wheeled vehicle, then this added weight towards the rear alters the vehicle's balance, impacts stability and handling dynamics during acceleration, braking, and cornering. Moreover, the aesthetic appeal of the vehicle can suffer as a bulky configuration detracts from its streamlined look.

[0004] Additionally, gaseous fuel vehicles typically have a dual-fuel system that includes both the gaseous fuel tank and the liquid fuel, such as petrol, tank. This configuration allows the vehicle to start on petrol and then switch to gaseous fuel once the engine has warmed up sufficiently and is running smoothly. An engine control unit (ECU) manages this transition automatically based on engine parameters such as temperature and load.

[0005] However, the two-wheeled vehicles compared to their multi-wheeled counterparts have a limited space available for additional components and integrating both the gaseous fuel tank and the petrol tank while maintaining the vehicle's compact configuration and ensuring rider comfort and safety is a critical engineering challenge.

[0006] Addressing these challenges requires innovative approaches to the gaseous fuel cylinder placement and integration. Alternative configurations must not only optimize space utilization but also ensure a balanced weight distribution and a lower center of gravity (CG) to enhance safety and ride quality. Current architectures often necessitate adjustments to vehicle dimensions and structural modifications, which can increase manufacturing complexity and costs.

[0007] In response to these challenges, there is a compelling need for an inventive solution that addresses the spatial constraints of the vehicles, while optimizing the placement of fuel systems to enhance performance, safety, and user comfort. This invention aims to achieve a balanced integration of fuel systems without compromising the vehicle's aesthetic appeal or functional capabilities.SUMMARY OF THE INVENTION
