• An appropriate amount of evaporative gas is fed into the dynamic chamber by the driving of the purge solenoid valve according to the engine operation conditions to ensure driveability and prevent release of evaporative gas into the atmosphere.
• The PCM determines the engine operation conditions based on the signals from the input devices indicated in the figure below to drive the purge solenoid valve. For the construction/operation of the purge solenoid valve, refer to “EMISSION SYSTEM, PURGE SOLENOID VALVE, CONSTRUCTION/OPERATION”.
