1 Answers
Faults caused by a damaged carbon canister purge solenoid valve include: 1. Abnormal noises during vehicle operation; 2. Strong fuel odor inside the vehicle; 3. Unstable engine idle; 4. Difficulty in starting the engine. The carbon canister purge solenoid valve is a device installed in cars or motorcycles to reduce air pollution caused by fuel vapor emissions and simultaneously improve fuel efficiency. The working principle of the carbon canister purge solenoid valve is: when the engine is turned off, the vehicle's activated carbon canister begins to absorb fuel vapors evaporating from the fuel tank and locks them in the micropores of the activated carbon inside the canister, preventing the fuel vapors from being released into the air. When the engine is started, the fuel vapors adsorbed in the carbon canister are delivered to the engine as fuel.
