  • Patent number: 11371420
    Abstract: A cooling arrangement for cooling charge air of a supercharged internal combustion engine. In a charge-air line that leads to the internal combustion engine, there are provided a compressor arrangement, which has at least one compressor stage, and an expansion arrangement, which has at least one expansion stage for lowering the pressure level and thus for cooling the charge air. A cooling device is provided between the compressor arrangement and the expansion arrangement. The at least one compressor stage and the at least one expansion stage are connected in series and are respectively connected in terms of drive to an electric motor. The compressor arrangement has at least two compressor stages connected in parallel.

  • Publication number: 20220145906
    Abstract: An exhaust turbocharger has a housing, in which a shaft is mounted by bearings, which carries a turbine wheel, on the one hand, and a compressor wheel, on the other hand. An electric machine has a rotor and a stator. The rotor is secured on the shaft for conjoint rotation therewith and the stator surrounds the rotor radially on the outside. A sleeve, which supports the rotor radially and axially, is arranged between the stator and the rotor. The sleeve has at least one fluid duct, by way of which a cooling fluid can be guided toward the bearings of the shaft.

  • Patent number: 10995658
    Abstract: An exhaust gas turbocharger system (1) has a first and second exhaust gas turbochargers (2, 3) arranged in parallel. Each exhaust gas turbocharger (2, 3) has an exhaust gas turbine (20, 30) and a compressor (21, 31). Fresh air compressed by the compressor (21) of the first exhaust gas turbocharger (2) can flow into a first pressure line (15), and fresh air compressed by the compressor (31) of the second exhaust gas turbocharger (3) can flow into a second pressure line (16). The two pressure lines (15, 16) are connected to each other in terms of flow. An electric drive device (10) is connected to the first exhaust gas turbocharger (2) and can be turned on for providing additional torque for driving the exhaust gas turbine (20) and the compressor (21) of the first exhaust gas turbocharger (2).

  • Patent number: 10641163
    Abstract: A supercharged internal combustion engine has cylinder groups with plural cylinders and plural exhaust gas turbochargers. Exhaust gas can be fed to at least one first exhaust gas turbocharger from first outlet valves of the cylinders of the first and second cylinder groups via at least one first exhaust manifold. Exhaust gas can be fed to at least one second exhaust gas turbocharger from second outlet valves of cylinders of the first and second cylinder groups via a second exhaust manifold. At low rotational speeds and/or in part load and/or non-steady state operation, exhaust gas can be fed via the first exhaust manifolds that are connected to the first outlet valves per cylinder group to a turbine of the first exhaust gas turbocharger in flows that can be divided in the inflow region of the turbine, while the second exhaust gas turbocharger is inactive.

  • Patent number: 10196967
    Abstract: A supercharging device is provided for an internal combustion engine that has at least one exhaust gas turbocharger (1, 2) and at least one charge air cooler (LLK) arranged in the outflow of the exhaust gas turbocharger (1, 2). An additional electrically driven compressor (e-booster 6, 7) is arranged downstream of the charge air cooler (LLK) in a bypass (5) to the main flow line (3) to the throttle valve (4) of the internal combustion engine. The main flow line (3) can be closed by a check valve (9) that acts in the direction of a return flow.
