Outline
Mechanical resistance loss has been reduced through structural changes to achieve optimum fuel economy. An oil shower pipe has been adopted as a part of this structural change.
Purpose, Function
The oil shower pipe injects engine oil to lubricate the contact points of the cam and rocker arm. As a result, wear resistance of sliding part is reduced.
Construction
The oil shower pipe is installed to the camshaft cap.

The oil shower pipe utilizes the engine oil injection holes at the top of the camshaft.

Operation
The oil shower pipe injects engine oil from the engine oil injection holes using hydraulic pressure.
