What is an EVAP (Fuel Evaporative System)?

The gasoline evaporative system, or EVAP, in your automobile is an important component of its emissions control system. Gasoline vapors from the fuel tank are captured and recirculated by the EVAP.

What Is an EVAP and How Does It Work?

The three main components of your car’s EVAP system are the fuel tank, the purge valve, and the charcoal canister.

When you start your car, the engine takes air from the environment. This air enters the fuel tank through the purge valve.

The purge valve functions similarly to a one-way valve, allowing air to enter the fuel tank but not the other way around. This reduces the risk of hazardous gasses escaping from the tank.

Gasoline vapors are picked up by the air going through the fuel tank that would otherwise be lost. The air enters the charcoal canister, which is packed with activated carbon pellets, after passing through the purge valve.

A chemical glue traps the gasoline vapors in the canister, where they are kept until your engine performs an EVAP system diagnostic test.
