What are the effects of a faulty car carbon canister?
1 Answers
Car carbon canister failure affects the vehicle's emissions. The function of the car carbon canister solenoid valve is to reduce air pollution caused by fuel evaporation emissions while improving fuel efficiency. When the car starts, the solenoid valve opens, releasing the adsorbed fuel vapor into the intake manifold to enter the engine for combustion. Solutions for a damaged carbon canister solenoid valve include: 1. Cleaning the fuel tank exhaust system; 2. Cleaning or replacing the carbon canister solenoid valve. The working principle of the carbon canister solenoid valve is to control the purging effect of the carbon canister through the modulation of electrical pulse width. The ECU computer, based on different engine operating conditions, grounds the solenoid valve circuit at a certain frequency to turn it on or off. The ECU computer controls the vacuum of the purging carbon canister by operating the normally closed solenoid valve.
