What is the lifespan of a carbon canister purge valve?

[DiAutumn]

The lifespan of an automotive activated carbon canister is approximately 4 years or 60,000 kilometers. The carbon canister is prone to clogging, which can prevent fuel vapors from being properly vented, leading to excessive pressure buildup in the fuel tank. Its primary functions are to reduce emissions pollution and improve fuel efficiency. Below are some key details about activated carbon canisters: 1. The carbon canister is installed between the fuel tank and the engine. Since gasoline is a highly volatile liquid, the fuel tank often contains vapors at normal temperatures. The fuel evaporation emission control system is designed to direct these vapors into the combustion process and prevent them from being released 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 there. Upon engine startup, the electromagnetic valve of the fuel vapor purge device, located between the activated carbon canister and the intake manifold, opens. This allows the gasoline vapors stored in the activated carbon canister to be drawn into the intake manifold and participate in the combustion process.
