Abstract: An internal combustion engine with combined pressure charging has an exhaust turbocharger turbine arranged in an exhaust conduit of the internal combustion engine driving a compressor arranged in an intake conduit. A mechanically driven supercharger is arranged downstream of the compressor and is coupled continuously variably to the engine via a Fottinger speed transformer with variable-pitch guide vanes and variable speed slip. To bypass the mechanically driven supercharger, a bypass conduit is provided. A circulating-air slide is arranged in the bypass conduit for controlling the air quantity bypassing the mechanically driven supercharger. The degree of opening of the circulating-air slide and the slip of the Fottinger speed transformer are controlled as a function of operating parameters such that the charge-air pressure is adjusted to a predetermined set point value.

Abstract: An exhaust-gas turbocharger for an internal-combustion engine is described, its turbine having a double flow housing with two channels for supplying the exhaust gases to the turbine wheel, of which on channel can be closed off as a function of a variable operating parameter by means of a sliding sleeve which is mounted in the housing so as to be axially displaceable by means of a control device. To ensure a clearly defined relationship between the adjustment of the sliding sleeve and the input variables and to create a heat-resistant control device, the sliding sleeve is connected to an axially fixed and circumferentially rotable driving ring via a positive sliding fit driving the sliding sleeve in the circumferential direction, a slot pin fixed to the housing engaging into an oblique helical groove in the sliding sleeve, and a shaft engaging on the driving ring via a positive connection and being guided radially out of the housing via a bearing in the latter.
