[0002] The carbon canister solenoid valve is a device installed on cars or motorcycles, primarily used to reduce air pollution caused by fuel evaporation emissions while improving fuel efficiency. It regulates fuel vapor emissions through electromagnetic control, ensuring that the vehicle can effectively control emissions under various operating conditions, thereby achieving environmental protection and energy conservation.
[0003] However, with the existing carbon canister solenoid valve, when the access end of the solenoid valve is connected to the engine pipeline, the high pressure of the fuel vapor discharged by the engine can easily cause the connection part between the solenoid valve and the engine pipeline to expand. If the expansion lasts for a long time, it can easily cause the pipeline to break, resulting in air leakage, a short service life, and thus unable to achieve the best use effect.
