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.
