GENERAL INFORMATION
Description
1 - Fuel Tank Assembly
3 - PCV Valve
Emission control system recovers and burns fuel vapor to prevent the vapor in fuel tank from being
discharged into the atmosphere. It monitors the oxygen content in exhaust gas, so as to guarantee the
maximum efficiency of catalyst assembly in converting the HC, CO and NOx in exhaust gas.
Activated charcoal canister assembly plays an important role in the emission control system. The activated
charcoal canister assembly can be used to absorb and filter moisture and fuel vapor. Fresh air enters the
bottom of activated charcoal canister assembly while fuel vapor enters the top of activated charcoal canister
through pipe. When engine stops operating, the fuel vapor and fresh air will be stored in the activated
charcoal canister assembly. When canister solenoid valve opens, the fuel vapor will enter intake manifold to
burn.
