EMISSION CONTROL SYSTEM(w/o Canister Pump Module)


  1. CONSTRUCTION


    1. TWCs are provided in the exhaust manifold sub-assembly of each bank and also in the front exhaust pipe assembly*.

      *: Except models compliant with EURO VId emission regulations

    2. An exhaust manifold sub-assembly with an integrated TWC is used. This realizes quick warm-up of the catalytic converter, helping to reduce emissions immediately after engine start.

    3. An ultra thin-wall, high-cell density, ceramic type TWC is used for each exhaust manifold sub-assembly and a thin-wall, ceramic type TWC is used for the front exhaust pipe assembly*.

      *: Except models compliant with EURO VId emission regulations

    4. These TWCs enable improved exhaust emissions through optimized cell density and wall thickness.
