Oil Spray Jet: Description and Operation

Lubricating Oil System

Oil spray jets

The temperature of the pistons in the Cayenne S and Cayenne Turbo engine is reduced by means of spray cooling. The spray jets are fitted on the upper part of the crankcase. The spray oil is also used for improved lubrication of the cylinder lining. To ensure the necessary engine oil pressure at low revs and high engine oil temperatures, the spray jets have an opening pressure of approx. -> pressure: 1.8 bar.
