ENGINE UNIT DETAILS VALVE MECHANISM

  1. CONSTRUCTION

    1. Each cylinder has 2 intake valves and 2 exhaust valves. Intake and exhaust efficiency is increased due to larger total port areas.

    2. The valves are directly opened and closed by 2 camshafts.

    3. The VVT-i system is used to achieve low fuel consumption, high engine performance and reduced exhaust emissions.
