• The cast iron 5 axis-hole, which has great rigidity, has been adopted for the camshaft to insure higher reliability.

• The endplay of the camshaft is regulated at the rear of the No. 1 journal.

• The lubricating oil is supplied through the oil supply hole at each journal. Additionally the cam nose part is chill coasted to improve the abrasion resistance and the width of cam hill part is shortened to reduce the weight.

• There is no positioning pin or key slot for the camshaft sprocket at the edge of the camshaft. The lubrication process has been adopted for the camshaft sprocket tightening bolt to prevent instability in the axis during tightening.

• There is an oil line, by which the oil is supplied to the variable valve timing actuator, located at the L3 Turbo engine models intake port side camshaft (front of camshaft).

• The high pressure fuel pump drive cam and CMP sensor detection lobe are located at the rear of the intake camshaft.
