Evaporative Emissions System: Description and Operation

TANK VENTING
The hydrocarbons created by vaporization of the fuel in the fuel tank are not released to the atmosphere across the tank vent but are instead collected in the carbon canister. This unit is installed in the rear left wheel housing.

To return these hydrocarbons into the combustion process, the carbon canister is purged with air and the carbon is regenerated in the process.
