The turbine and the compressor of the turbocompressor unit are adapted to each other and to the engine in such a way that the pressure on the inlet side of the turbine is always higher than the pressure on the pressure side of the compressor. The rotary shaft of the unit is coupled via a drive chain containing a continuously variable transmission to the crank shaft of the engine. An electronic control unit controls the transmission ratio and the degree of opening of the valve. |
