Fuel Evaporative Canister Replacement
What is a fuel evaporative canister?
The fuel evaporative canister, also called the charcoal canister, is an emission control device that traps vapors from fuel evaporation, and sends them to the fuel tank for later use.
How does the fuel evaporative canister work?
The EVAP system uses the charcoal canister to store fuel vapors that escape the cas tank through a tube. The charcoal (EVAP_ canister empties by engine vacuum sucking the vapors out, to be burned as fuel. This can only be done when the vent valve and purge valve are opened simultaneously. When the vent valve and purge valve are closed, the evaporative canister will store vapors until the vents are opened. This allows environmentally harmful fuel vapors from entering the atmosphere, and increases fuel mileage over a tank of fuel.
