Evaporative Emissions System: Description and Operation
Evaporative Emissions Control System Schematic
SYSTEM DESCRIPTION
The Evaporative Emission Control System (EECS) uses the basic charcoal canister storage method. This method transfers fuel vapor from the fuel tank
to an activated carbon storage canister. This retains the fuel vapors when the vehicle is not operating. When the engine is running, the fuel vapor is
purged from the carbon element by intake air flow, and consumed in the normal combustion process.
