Car carbon canister What is the general lifespan of a solenoid valve

The lifespan of a car's activated carbon canister is 4 years or 60,000 kilometers. The carbon canister is easily clogged. Once clogged, the fuel vapor will have nowhere to discharge, resulting in excessive exhaust gas pressure in the fuel tank. The function is to reduce emission pollution and reduce fuel consumption.

About activity The information of the carbon canister is as follows:

1. The carbon canister is installed between the gasoline tank and the engine. Since gasoline is a volatile liquid, the fuel tank is often filled with vapor at normal temperature. The function of the fuel evaporation emission control system is to introduce the vapor into combustion and prevent it from evaporating to In the atmosphere. Activated carbon canister storage plays an important role in this process.

2. When the engine is turned off, the gasoline vapor and The fresh air is mixed in the tank and stored in the activated carbon can;when the engine is started, the fuel evaporation purification device installed between the activated carbon can and the intake manifoldSolenoid valve door opens, and the gasoline vapor in the activated carbon canister is sucked into the intake manifold to participate in combustion.

How often should the car carbon canister solenoid valve be replaced?

The car carbon canister solenoid valve should be replaced every 3 to 5 years. The solenoid valve can be divided into shift solenoid valve, locking solenoid needle valve and pressure regulating solenoid needle valve according to its function;according to the working mode, It is a switch type solenoid valve and a pulse type solenoid valve. Carbon canister solenoid valves are usually used to cut off the flow of oil, water, gas and other substances, and cooperate with electrical equipment such as pressure and temperature sensors to achieve automatic control. The carbon canister solenoid valve is a device installed on the car to reduce air pollution caused by fuel evaporation emissions and increase fuel efficiency at the same time. When the car is started, Solenoid ValveOpen to release the adsorbed fuel vapor as fuel into the intake pipe and enter the engine for combustion.
