EVAP Canister Purge Pump
FUNCTIONS WITHIN THE SYSTEM
The ECM turns the purge pump relay ON/OFF and controls the EVAP canister electric purge pump.
INDIVIDUAL FUNCTION WITHIN THE SYSTEM
EVAP canister electric purge pump has multiple rotation modes, and each mode is changed depending on parameters such as driving conditions and estimated purge gas density.
INDIVIDUAL OPERATION
Since the amount of intake manifold negative pressure development is insufficient due to engine downsizing, and the amount of purge gas processed is insufficient by itself, the supercharged purge system (system with a pump) is adopted. In the supercharged purge system, supercharging is performed by a purge pump, and the purge is inserted into the clean side duct under atmospheric pressure.
Component Location
EVAP canister electric purge pump is installed between EVAP canister purge volume control valve and EVAP canister.
