DESC:TECHNICAL FIELD
[001] The embodiments herein generally relate to canister arrangement in vehicles and more particularly, but not exclusively to canister arrangement in motorcycles.

BACKGROUND
[002] Generally, a canister is a device used for adsorbing fuel vapours generated in a fuel tank of a motorcycle and to provide the adsorbed fuel vapours to an engine of the motorcycle for combustion. Usage of canister prevents the emission of unburnt fuel vapours to the atmosphere and helps in achieving stringent emission norms.
[003] Mounting location of the canister in the motorcycle depends on various factors such as, the distance between the canister and the engine of the motorcycle, safety of the canister and the aesthetics of the motorcycle. The distance between the canister and the engine must be such that the conduits connecting the canister, the fuel tank and the engine is at optimum length while the canister is not too close to the engine to prevent any fire hazard. Further, the canister should be protected from any physical damages during operation of the motorcycle. Furthermore, the location of the canister in the vehicle must not affect the aesthetics of the motorcycle.
[004] The aforementioned factors affecting the mounting location of the canister in the motorcycle varies based on the frame of the motorcycle and the location of other components like engine, air filter etc.,
[005] Therefore, there exists a need for a canister arrangement for a motorcycle.

OBJECTS
[006] The principal object of an embodiment of this invention is to provide a canister arrangement for a motorcycle.
[007] Another object of an embodiment of this invention is to provide a canister arrangement for a motorcycle that improves safety of the canister.
[008] Yet, another object of an embodiment of this invention is to provide a canister arrangement for a motorcycle that doesn’t affect the aesthetics of the motorcycle.
