Abstract: A turbine, driven from the exhaust gases of the internal combustion engine, and having a speed-flow volume and pressure differential characteristic which is only little speed-dependent drives a Foettinger hydrodynamic torque converter which has a pump element which is highly speed-dependent, a radial flow turbine which is only little speed-dependent, and a guide vane element, the radial flow turbine of the fluid coupling driving a displacement-type rotary compressor so that, even at low engine speeds of the internal combustion engine, substantial supercharging effect can be obtained, whereas, as the engine speed increases, less supercharging effect will be obtained so that the average cylinder pressure at low speeds will be increased of cylinder pressure and engine torque will increase with decreasing speed, keeping the output power constant over a wide range of engine-operating speeds.
