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

The replacement cycle for a car's activated carbon canister is every 4 years or 60,000 kilometers. The carbon canister is prone to clogging, which can prevent fuel vapors from escaping, leading to excessive pressure from exhaust gases in the fuel tank. Its function is to reduce emission pollution and lower fuel consumption. Here is some information about the activated carbon canister: 1. The carbon canister is installed between the gasoline tank and the engine. Since gasoline is a highly volatile liquid, the fuel tank often fills with vapor at normal temperatures. The fuel evaporation emission control system's role is to direct these vapors into the combustion process and prevent them from escaping into the atmosphere. The activated carbon canister storage device plays a crucial role in this process. 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, allowing the gasoline vapors in the activated carbon canister to be drawn into the intake manifold for combustion.
