Motorcycle fuel evaporation system and motorcycle thereof

Abstract

The invention discloses a motorcycle fuel evaporation system and a motorcycle thereof. The system comprises a fuel evaporation pipe, a carbon tank and a fuel tank lock body, wherein the fuel tank lock body is provided with a gas path; one end of the gas path is communicated with the fuel tank, and the other end is communicated with the fuel evaporation pipe and is sealed with the outside; the fuel evaporation pipe is connected between the carbon tank and the gas path; and the port of the fuel evaporation pipe is positioned on the position out of the engine fuel tank and is communicated with the gas path in the fuel tank lock body. Fuel steam can smoothly enter and exit via the gas path, and liquid is blocked because the port of the fuel evaporation pipe is positioned out of the fuel tank.When the motorcycle fuel evaporation system is applied to the motorcycle, fuel can be prevented from splashing or infiltrating into the fuel evaporation pipe so as to prevent the fuel evaporation pipe from being blocked, thereby guaranteeing balanced pressure in the fuel tank, bringing convenience for lowering emission and fuel consumption, prolonging the service life of the carbon tank and guaranteeing the dynamic performance and the use performance of the whole motorcycle. A gas and fuel separator, a dumping valve and other components are omitted, which lowers cost and makes the structural arrangement of the whole motorcycle simpler.

Description

technical field [0001] The invention relates to a motorcycle component and the motorcycle, in particular to a motorcycle component assembly used for fuel evaporation and the motorcycle. Background technique [0002] Motorcycle fuel evaporation system is an essential part of its engine, generally including carbon canister, fuel evaporation tube and necessary accessories. It is mainly used to prevent the gasoline in the fuel tank from volatilizing into the atmosphere or causing danger. At the same time, it can ensure the air pressure balance in the fuel tank and prevent the engine from stalling due to insufficient fuel supply. When in use, after the engine is turned off, gasoline vapor and fresh air are mixed in the tank and stored in the activated carbon tank. When the engine is started, the electromagnetic valve installed between the activated carbon tank and the intake manifold is opened, and the activated carbon tank Gasoline vapor inside is brought into the cylinder by t...

AI Technical Summary

Problems solved by technology

There is no obvious anti-splash and anti-seepage measures between the oil-water separator and the fuel evaporation pipe. Therefore, when the fuel evaporation pipe is running or the whole vehicle is dumped, the fuel will splash or seep into the fuel evaporation pipe due to the vibration of the whole vehicle. It may cause pipeline blockage, affect the use of the carbon tank, and affect the internal air pressure of the fuel tank, and finally cause the motorcycle to experience slow or no fuel supply, thus affecting the normal operation of the engine
