| Description and Operation The evaporative emission fuel vapor management system comprises a carbon canister and a purge valve. A combination of plastic and rubber pipes connect the carbon canister to the fuel tank and the purge valve and to the inlet manifold. When the purge valve is closed, the fuel tank is vented into the carbon canister which absorbs the fuel vapor and prevents release of hydro-carbons into the atmosphere. When the purge valve is activated, the carbon canister is exposed to inlet manifold vacuum and the fuel vapor deposits are drawn into the inlet manifold where they mix with the incoming air/fuel charge. The evaporative emission fuel vapor management system is controlled by the powertrain control module according to calibrated data tables. |
