The evaporative emission fuel vapor management system consists of an evaporative emission canister and a canister purge valve. A combination of rigid and flexible low permeation hoses connect the fuel tank to the evaporative emission canister and canister purge valve intake manifold.
To satisfy LEV2 emission requirements, the fuel vapor management system uses a solenoid controlled canister close valve and a fuel tank pressure sensor which are used during the engine management system on-board diagnostic routines.
When the canister purge valve is closed, the fuel tank vapor is vented into the canister through the fuel tank roll-over valves. The canister absorbs the fuel vapor and prevents the release of hydrocarbons into the atmosphere. When the vapor management valve is cycled, the canister is exposed to the intake manifold vacuum and the fuel vapor deposits are drawn into the manifold where they mix with the incoming air/fuel charge. This air/fuel mixture ratio is controlled by the engine management system.
The evaporative emission fuel vapor management system is controlled by the engine control module (ECM) according to calibrated data tables.
