What is the function of the canister purge solenoid valve in a car?
1 Answers
The canister purge solenoid valve in a car mainly serves the following purposes: 1. The canister purge solenoid valve is a device installed in cars or motorcycles to reduce air pollution caused by fuel vapor emissions while simultaneously improving fuel efficiency. 2. When the engine is turned off, the vehicle's activated carbon canister begins to absorb fuel vapors evaporating from the fuel tank and securely locks them within the micropores of the activated carbon in the canister, preventing the fuel vapors from being released into the atmosphere. 3. When the engine is started, the canister purge solenoid valve opens, releasing the adsorbed fuel vapors into the intake manifold to be burned in the engine.
