The canister purge valve does not have a fixed replacement interval. The function and working principle of the canister purge valve are as follows: Function of the canister purge valve: The canister purge valve is a device installed in cars or motorcycles to reduce air pollution caused by fuel vapor emissions and simultaneously improve fuel efficiency. Working principle of the canister purge valve: When the car engine is turned off, the canister begins to absorb fuel vapors evaporating from the fuel tank to prevent them from being released into the atmosphere and causing environmental pollution. When the car engine is started, the fuel vapors adsorbed in the canister are then delivered to the engine as fuel for operation.
