VF-135 MC853421 Solenoid Valve

  The Solenoid valve is generally near the throttle valve and is a three-way valve.

  The carbon canister is generally installed between the gasoline tank and the engine. Since gasoline is a volatile liquid, the fuel tank is often full of vapor at normal temperature, and the function of the fuel evaporative emission control system is to introduce the vapor into combustion and prevent it from volatilizing into the atmosphere. An important part of this process is the activated carbon canister storage device.

  Because activated carbon has an adsorption function, when the car is running or turned off, the gasoline vapor in the fuel tank enters the upper part of the activated carbon tank through the pipeline, and the fresh air enters the activated carbon tank from the lower part of the activated carbon tank. 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 Solenoid Valve of the fuel evaporation purification device installed between the activated carbon tank and the intake manifold is opened, and the activated carbon Gasoline vapors in the tank are drawn into the intake manifold for combustion.
