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.
Oil filter with oil-to-water heat exchanger M57 E38/E39
• Mounted directly on the engine block
• The water for the oil-to-water heat exchanger is supplied
directly from the engine block (crankcase)
• In the same way as on the M47, the water outlet is located on
the oil-to-water heat exchanger
