Camshaft

• The camshafts are made of cast iron alloy.

• An oil passage is provided on the intake and exhaust camshafts in order to supply engine oil to the VVT-i system.

• A VVT-i controller has been installed on the front of the intake and exhaust camshafts to vary the timing of the intake and exhaust valves.

• Together with the use of the roller rocker arm, 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.
