Piston cooling system

P0006023
Here piston cooling oil flow is illustrated when the
valve (E) is open and the valve (F) balances oil flow
to the piston cooling channels. The piston cooling
nozzle is directed such that the oil jet hits the inlet hole
to the piston cooling chamber.
By regulating the piston cooling flow via a control
valve, a so-called optimized piston cooling system is
arrived at with a constant flow regardless of engine
rpm.
