Carbon Tank Electromagnetic Valve Noise Solution Research
This article summarizes the working principles of the carbon canister desorption system and carbon canister solenoid valve under the background of the national emission regulation Ⅵ,and deeply analyzes the causes of increased noise of the carbon canister solenoid valve.By building a carbon canister solenoid valve drive platform and using testing methods,effective measures to reduce noise are studied.These measures include optimizing the design of the carbon canister solenoid valve,adding a freewheeling diode,and optimizing the placement of the carbon canister solenoid valve.
