ENGINE UNIT


  1. CONSTRUCTION


    1. The camshafts are made of cast iron alloy.

    2. A timing rotor for the camshaft position sensor is provided on the intake camshaft and exhaust camshaft.

    3. The cam that drives the fuel pump assembly (for high pressure) is positioned between the No. 4 cylinder and the end of the exhaust camshaft to achieve size reduction. Also, a pump cam with 4 peaks is used in the cam that drives the fuel pump assembly (for high pressure) and by synchronizing fuel pressure-feeding and fuel injection, the difference in fuel pressure between cylinders is reduced.

    4. The vacuum pump assembly is driven by the end of the exhaust camshaft.
