Fuel Evaporation System: Description

Evaporative Emission Control System (EECS), is designed to prevent raw fuel vapors from escaping to the atmosphere. System consists of venting system which allows only vaporous fuel to be drawn into the system.

During periods of engine operation, vapors are drawn through system vent lines and into intake manifold. When engine is off, fuel vapors are stored in charcoal of vapor storage canister. Vapors are then drawn into the intake manifold when the engine is running again. See Figure .
