  • Compressor rotor structure and method for arranging said rotor structure
    Patent number: 11959485
    Abstract: Compressor rotor structure and methodology for harmonizing compressor aerodynamics and rotordynamics are provided. Disclosed embodiments benefit from a compressor design effective for improving rotordynamics (e.g., stiffer rotor structure) without reducing a usable aerodynamics range of the compressor. This design may involve variation of the rotor structure along the rotor axis to locate respective surfaces defined by respective inlets of the one or more impellers at a varying distance relative to the rotor axis based on respective ratios selected for the configuration of the impeller bodies. This arrangement may be effective for improving rotordynamics while satisfactorily meeting the respective varying aerodynamics requirements at the various compression stages by the impeller bodies.

  • Method for cylinder equalization of a lambda-controlled internal combustion engine, in particular of a motor vehicle
    Patent number: 9546608
    Abstract: In a method for cylinder equalization of a lambda-controlled internal combustion engine of a motor vehicle, cylinders to be tested are trimmed with respect to the mixture composition of metered fuel, and the cylinder equalization is carried out on the basis of an uneven running or uneven running change of the internal combustion engine caused by the trimming. In addition, the uneven running or uneven running change is detected in a reference state of the internal combustion engine. The uneven runnings or uneven running changes detected during successive trimmings of the cylinders to be tested are and compared to the uneven running values detected in the reference state.

  • METHOD FOR DIAGNOSING A FUNCTION OF AN INTERNAL COMBUSTION ENGINE
    Publication number: 20160377010
    Abstract: A method for diagnosing a function of an internal combustion engine, which includes one injector of an intake-manifold injection, one injector of a direct injection and one cylinder. Fuel may be applied to the cylinder with the aid of the injector of the intake-manifold injection and/or with the aid of the injector of the direct injection. The method includes the steps of determining an operating state of the internal combustion engine, which is characterized by an injection and/or injections used for injecting fuel into the cylinder, selecting a diagnostic function for the cylinder as a function of the determined operating state and carrying out the selected diagnostic function for the cylinder.
