Device features

The system prevents the fuel vapor recovery system out of food in an atmosphere of fuel vapors, adversely affecting the ecology of the environment.

The system used the method of vapor absorption carbon adsorber. It is mounted on the base stand and the right rear pipes connected to the fuel tank and a purge valve.

The engine compartment is located canister purge solenoid valve, which signals the engine control unit switches the operation modes of the system.

Fuel vapors from the fuel tank continuously discharged via line and accumulated in the adsorber filled with activated charcoal (adsorbent). When the engine is regenerated (recovery) adsorbent canister purge of fresh air coming into the system by the action of vacuum transferred through a pipeline from the diffuser throttle knot in the cavity by opening the canister purge valve. The controller controls the degree of the canister purge, depending on the mode of operation of the engine, giving a signal to the control valve with variable pulse frequency.

Fuel vapor from the adsorber via line enters the intake pipe of the engine and are burned in the cylinders.

Malfunction of the fuel vapor recovery system entail instability idling, stop the engine, increased exhaust emissions and the deterioration of the driving characteristics.
