A cartridge for use in a pulse energy enhanced turbine of a turbocharger. At least first and second fixed separating blades () are provided between a nozzle ring () and a disk (), the separating blades () maintaining separation of exhaust gas flows through a guide grid between a divided volute and a turbine wheel (). Exhaust pulsation energy from different cylinders or cylinder groups of an engine or engine bank are kept separated up to the turbine wheel, so that the turbine wheel reacts to individual pulses of exhaust gas flow from engine exhaust ports.

Cartridge for pulse-separated variable turbine geometry turbochargers

The invention relates to a compressor for inducting an internal combustion engine, comprising an electric motor () for driving a first compressor wheel (), wherein, in at least one operating state, an inlet-side, first gas flow () of the internal combustion engine () is compressed by the compressor (), wherein the compressor () comprises a first compressor path () for the first gas flow () and a second compressor path () for a second gas flow (), wherein the second gas flow (), in particular, in at least one operating state, opens into an exhaust gas flow () of the internal combustion engine () as a secondary air flow ().

Turbocharger for an internal combustion engine

A compressor with a compressor housing in which a compressor wheel is arranged. The compressor additionally includes a cartridge which is arranged in the compressor housing in the area of a compressor inlet. The cartridge is designed to variably change the cross section of the compressor inlet.
