Motorcycles activated carbon tank is dependent on carburetor negative pressure desorption work, the amount of desorption and desorption of adsorption off the size of the desorption port are closely related to the volatility from the fuel tank volatile mainly HC Other volatile gasoline components.
Because of such an important function, the state decided that China will implement the mandatory emission standards for motorcycle exhaust after July 2010, and the canister will basically be adopted by then.
Gasoline is a volatile liquid. The fuel tank is often filled with steam at ambient temperature. The function of the fuel evaporation control system is to introduce the vapor into the combustion and prevent it from evaporating into the atmosphere. The process plays an important role in the storage of activated carbon canisters. Because activated carbon has adsorption capacity, when the car is running or is shutting down, the gasoline vapor in the fuel tank goes into the upper part of the activated carbon canister through the pipe. Fresh air enters the activated carbon canister from the lower part of the activated carbon canister. After the engine is shut off, the gasoline vapor and the fresh air are mixed in the tank and stored in the activated carbon tank. When the engine is started, the electromagnetic valve of the fuel evaporating and purifying device installed between the activated carbon tank and the intake manifold is opened, Gasoline vapor is drawn into the intake manifold for combustion.
