Course contents/Background material
Oil filter with integrated oil-to-water heat exchanger
The oil-to-water heat exchanger is connected to both the oil circuit
as well as the water circuit of the engine. This arrange
ment
ensures the engine oil is heated faster by the coolant when
the
engine is cold and is effectively cooled by the coolant when
the
engine is at operating temperature.
Shortening the warm-up phase greatly contributes to reducing
fuel consumption.

Mounted directly on the engine block
The water for the oil-to-water heat exchanger is supplied
directly from the engine block (crankcase)
