ENGINE UNIT


  1. CONSTRUCTION


    1. The camshafts are made of cast iron alloy.

    2. Oil passages are provided in the intake and exhaust camshafts in order to supply engine oil to the VVT-iW system and VVT-i system.

    3. Camshaft timing gear assemblies (LH and RH) and camshaft timing exhaust gear assemblies (LH and RH) are installed on the front of the camshafts to vary the timing of the intake and exhaust valves.

    4. Together with the use of the No. 1 valve rocker arm sub-assembly, the cam profile has been designed with an indented R (radius). This results in increased valve lift when the valve begins to open and finishes closing, helping to achieve enhanced output performance.
