•  A cast iron, highly rigid 5-axis hole camshaft has been adopted to insure higher reliability.

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

•  Lubricating oil is supplied from inside of the camshaft to each journal.

•  Additionally the cam lobe part is chill cast to improve wear resistance, and the width of the cam heel part is shortened to reduce weight.

•  The enhanced smooth-finishing precision on the cam lobe contact surfaces enables reduced friction and improved quietness.

•  There is an oil line supplying oil to the variable valve timing actuator located on the intake port side camshaft (front of camshaft).

•  The intake side camshaft has a detection unit on the camshaft position (CMP) sensor integrated with the camshaft.
