carbon
Lift the carbon canister and dismount it from the
bracket on inner lining of left fender.
The air flow rate is controlled by the opening of evaporation by-pass passage in EVAP carbon canister
solenoid valve. The solenoid valve will repeat the operations of “ON” and “OFF” with signal from ECM
to actuate the variation of valve opening, so as to optimize engine control. The optimum value
memorized in ECM lies on the state of engine. When the engine operates, flow rate of fuel evaporation
from EVAP carbon canister is adjusted along with the variation of air flow.
Instruction of
Flow rate of fuel evaporation from EVAP carbon canister is controlled by duty cycle of ON/OFF of the
solenoid valve. The solenoid valve is actuated by ON/OFF duty cycle signal from ECM. The wider the
pulse width in “ON” condition is, the more fuel evaporation
a.
