Mode of operation

The turbocharger is a turbomachine consisting of the following main components:

August 2017HZTL2412_ENRevision F

€ Turbine

€ Compressor

These are mounted on a common shaft.

Exhaust gases from the diesel or gas engine flow through the turbine casing (10) and the nozzle ring (9) to impinge on the turbine (7).

The turbine (7) uses the energy contained in the exhaust gas to drive the compressor wheel (13). The compressor draws in fresh air, compresses it and then forces it into the engine's cylinders.

The exhaust gases escape into the ambient air through the exhaust gas pipe, which is connected to the gas outlet flange (8).

The air, which is necessary for operation of the diesel or gas engine and is compressed in the turbocharger, is drawn into the compressor wheel (13) through the suction branch or filter silencer (1). It then passes through the diffuser (3) and leaves the turbocharger through the outlet on the compressor casing (2).

The rotor runs in two radial plain bearings (6), which are located in the bearing flanges (11/12) between the compressor and the turbine. The axial thrust bearing (5) is located between the two radial plain bearings.

The bearings are connected to a central lubricating oil duct which is supplied by the engine's lubricating oil circuit. The oil outlet is always at the lowest point of the bearing casing (4).
