Schematic diagram of fuel evaporation system
The fuel evaporation system is used to reduce hydrocarbon compositions emitted into ambient air from
fuel system. Reduction of hydrocarbon is achieved by using active carbon in EVAP carbon canister.
When the engine is stopped or fuel is filled, the fuel evaporation from sealed fuel tank will be
introduced into EVAP carbon canister with active carbon and stored there. During operation of engine,
the fuel evaporation in EVAP carbon canister will be introduced into intake manifold through clean
passage. EV
AP carbo
n canister is contro
lled by ECM. With engine runni
ng, evaporation flow contro
lled
by EVAP canister solenoid is adjusted with direct proportion of increased air flow. During deceleration
and idling, the evaporation passage may be cut off by EVAP carbon canister solenoid.
