What is the purpose of the canister purge valve?
1 Answers
The canister purge valve, as part of the engine's gasoline evaporation control system, is installed between the fuel tank and the engine. Its working principle and function involve utilizing activated carbon's adsorption properties to collect fuel vapors during normal engine operation. The roles of the canister purge valve in a vehicle are as follows: 1. Reduce air pollution caused by fuel evaporation emissions from the vehicle. 2. Improve the vehicle's fuel efficiency. Information about the canister purge valve includes: 1. The solenoid valve is an automated fundamental component for fluid control using electromagnetic force, which can be integrated with circuits to achieve desired control. Inside the solenoid valve, there is a sealed chamber connected to different oil pipes, allowing hydraulic oil to enter various pipes, thereby controlling mechanical movement by switching the electromagnet's current on and off. 2. When the engine is turned off, gasoline vapors mix with fresh air inside the canister and are stored in the activated carbon canister. When the engine starts, the solenoid valve of the fuel evaporation purification device, located between the activated carbon canister and the intake manifold, opens, drawing the gasoline vapors from the canister into the intake manifold for combustion.
