2 Line to Engine
The fuel vaporization control system is in stalled to inhibit the fuel vaporized gas from discharging into the
atmosphere.
The fuel vaporized gas that is accumulated in the canister abstracts through the purge control valve purification
during the engine combustion (except the decreasing mode) and coolant temperature of over
80 ° C. For this reason, the Engine Control Module (ECM) transacts the engine speed, air inflow quantity, coolant
temperature, and intake temperature.
The purge control valve is activated by the ECM frequency according with the engine rotating speed to adjust the
purification rate. The purification rate is determined by the continuous valve opening interval.
The purge control valve is activated by the ECM for the following conditions:
•
Coolant temperature of over 80 °C
•
Engine speed of over 1,000 rpm
•
2 minutes after starting
•
When the fuel cut-off mode is not activated
