EMISSION CONTROL SYSTEM SYSTEM DIAGRAM


  1. EMISSION CONTROL AND EVAP CONTROL SYSTEM ILLUSTRATION

    To reduce HC emissions, the following occurs. First, evaporated fuel in the fuel tank is absorbed by the canister's active carbon. Then, when the vehicle is being driven, the fuel in the canister and the air are routed into the intake manifold for combustion.

  2. SECONDARY AIR INJECTION SYSTEM ILLUSTRATION (w/ Secondary Air Injection System)

    During a cold engine start, this system purifies the catalyst exhaust fumes by applying air pressure to the air hose, exhaust manifold and cylinder head exhaust port.
