EMISSION CONTROL SYSTEM


  1. OUTLINE


    1. Exhaust Emission Control System


      1. Three-Way Catalysts (TWCs) are used to reduce emissions in the exhaust gas.

      2. Based on the signals from the air fuel ratio sensors and oxygen sensors, the ECM controls the fuel injection volume in order to optimize exhaust gas emissions.

    2. Evaporative Emission Control System


      1. The ECM controls the purge flow of evaporative emissions (HC) in the charcoal canister in accordance with the engine conditions.
