How long does a charcoal canister last in a car?
The charcoal canister is the centerpiece of the evaporative emission control (EVAP) system, a technology designed to prevent vapors from your fuel tank from escaping into the atmosphere. The charcoal canister seldom fails and should last the life of the car.
What can cause a charcoal canister to fail?
In most cases, EVAP system problems are not caused by the canister itself but by related valves. In some rare instances, however, the canister can crack or become clogged. Also, a failure somewhere else in the fuel or EVAP system can allow gasoline to enter the canister, ruining it.
What’s the vent valve on a charcoal canister?
Today’s vehicles also feature a vent valve in the charcoal canister’s fresh-air hose. When the system needs to be tested for leaks, the valve is used to keep the canister shut. During purge, the valve opens to allow airflow.
Why do you need a charcoal canister for EVAP?
The charcoal canister is the centerpiece of the evaporative emission control (EVAP) system, a technology designed to prevent vapors from your fuel tank from escaping into the atmosphere.
How does a charcoal canister work in a car?
How the charcoal canister works. Once the vehicle is running and the engine is at regular speed, the vapors are “purged.” A valve opens to draw fresh air through the canister, carrying the gases into the engine, where they’re burned. Today’s vehicles also feature a vent valve in the charcoal canister’s fresh-air hose.
