Patents by Inventor Cathrin BERGNER

Cathrin BERGNER has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240337199
    Abstract: A cartridge for use in a pulse energy enhanced turbine of a turbocharger. At least first and second fixed separating blades (12) are provided between a nozzle ring (6) and a disk (29), the separating blades (12) maintaining separation of exhaust gas flows through a guide grid between a divided volute and a turbine wheel (11). 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.
    Type: Application

  • Patent number: 11220955
    Abstract: The invention relates to a compressor for inducting an internal combustion engine, comprising an electric motor (3) for driving a first compressor wheel (4), wherein, in at least one operating state, an inlet-side, first gas flow (5a) of the internal combustion engine (1) is compressed by the compressor (2), wherein the compressor (2) comprises a first compressor path (5) for the first gas flow (5a) and a second compressor path (6) for a second gas flow (6a), wherein the second gas flow (6a), in particular, in at least one operating state, opens into an exhaust gas flow (8) of the internal combustion engine (1) as a secondary air flow (6a).
