ENGINE UNIT


  1. CONSTRUCTION


    1. The intake camshaft (camshaft) and exhaust camshaft (No. 2 camshaft) are made of cast iron alloy.

    2. An oil passage is provided in the intake camshaft (camshaft) and exhaust camshaft (No. 2 camshaft) in order to supply engine oil to the Dual VVT-i system.

    3. A VVT-i controller (camshaft timing gear assembly or camshaft timing exhaust gear assembly) is installed on the front of the intake camshaft (camshaft) and exhaust camshaft (No. 2 camshaft) 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.

    5. A timing rotor for the cam position sensor (No. 1 crank position sensor) is provided on the back of the intake camshaft (camshaft) and exhaust camshaft (No. 2 camshaft).
