EMISSION CONTROL SYSTEM GENERAL


  1. OUTLINE


    1. Exhaust Emission Control System


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

      2. An air injection system is used.*

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


        • *: Models for compliant with EURO 5 emission regulations

    2. Evaporative Emission Control System


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