What is a Fuel Evaporative System?
A critical part of the emissions control system of your car is its fuel evaporative system. The gasoline Vapors are captured and recirculated by the EVAP.
Reducing emissions is achieved by burning the vapors in the engine. The two types of EVAP systems are open and closed.
Vapors can escape into the atmosphere through an open system. There is a closed system that traps the vapors in a canister.
How Does an EVAP Work?
The fuel tank, purge valve, and charcoal canister are the main parts of your car’s EVAP system.
When you start your vehicle, the engine draws in the air. This air enters through the purge valve.
The purge valve allows air to go into the fuel tank, but not the other way around. Vapors from the tank are prevented from escaping.
The air passing through the fuel tank picks up the gasoline vapors. The air goes into the charcoal canister after the purge valve.
When your engine runs a diagnostic test on the EVAP system, the gasoline vapors are trapped in the canister by a chemical glue.
Annual Emissions Testing and EVAPs
During an emissions inspection, your car’s fuel evaporative system is tested to make sure it works correctly.
The inspector will open the engine of your car. The inspector will be pulling up to 30mph to watch for leaks.
If you have a question about the fuel system of your car, please get in touch with a mechanic.
