The internal combustion engine (1) has a compressor (5) for compressing the air fed into the engine, whereby a defined desired charging pressure is adjusted via a final control element (10) in a bypass (15) to the compressor. A desired air mass flow throug...

The internal combustion engine is especially a diesel engine and has a turbocharger and a supercharger with a belt drive from the engine. Throttle valves may control the distribution of the air supply to the engine. The control circuit may incorporate a to...

The present invention relates to the thermal modelling of a switched reluctance motor (14) for supercharging an internal combustion engine (1). A supercharger system comprises: an electric motor driven compressor (10) for supercharging the engine (1), the ...

The charging system has an electrically powered compressor (11) and a bypass line (5) for the compressor with a bypass flap (4) connected to an actuator that enables active adjustment of the bypass flap. The flap is connected to a regulator (6) and can be ...

A bypass (50) around the compressor/turbo charger (20) has a valve (60) to open and close it. Valve and/or bypass contain an acoustic element (70). This is formed by a resonance chamber, closed on one side, and positioned in or at an angle to a feed pipe (...

An internal combustion engine (10) is provided with at least one intake manifold (14) and a turbocharger. The turbocharger includes a rotatable shaft (32); a turbine having a turbine wheel carried by the shaft (32); and a multi-stage compressor (16). The m...
