Charging increases the performance of the engine in the upper partial loading and full loading ranges.

The compressor (50) compresses the intake air and therefore increases the degree of filling of the cylinder.
The metered fuel quantity is increased as a result of the rise in the air quantity. This increases the torque produced and the engine performance.

The cylinder volumetric efficiency is improved by the charge air cooler (110/2) as well as the NOX generation is reduced by lower exhaust gas temperatures.

The water-cooled charge air cooler is located between compressor and engine and has a single cooling circuit (low temperature circuit).


The drive power needed to drive the compressor is taken from the crankshaft over a separate belt drive.
The magnetic coupling of the mechanical supercharger (Y2/1) is responsible for switching the compressor on and off.

The charge air temperature and the charge air pressure are measured from the charge air distributor and sent to the ME control unit in order to allow adjustment of the correct fuel quantity for the degree of filling of the cylinder.
