    Abstract: A method for controlling an inlet-adjustment mechanism in an air inlet for a compressor so as to switch the mechanism between open and closed positions for adjusting a flow area of the inlet. The method includes an algorithm for determining when the inlet-adjustment mechanism is in a failure mode. In accordance with the method, when the operating point on the compressor map is on the high-flow side of a threshold line at which the inlet-adjustment mechanism is switched from one position to the other, a measured speed or pressure ratio is compared to a theoretical value for the speed or pressure ratio based on a compressor map for the open position of the mechanism. If the measured value differs from the theoretical value by more than a predetermined tolerance, a failure mode is indicated.

  • Patent number: 10526955
    Abstract: A supercharging device is disclosed for an internal combustion engine having an exhaust-gas turbocharger and a fresh-air compressor. The supercharging device includes a recuperation charger which has a compressor-turbine with a high-pressure side and a low-pressure side and which has an electromechanical motor-generator coupled to the compressor-turbine. The compressor-turbine is operable at least firstly when the supercharging device is configured in a booster operating mode in a manner driven by the motor-generator as a compressor for increasing the pressure of charge-air mass flow to the intake tract of the engine, and secondly when the supercharging device is configured in a recuperation operating mode in a manner driven by the charge-air mass flow as a turbine for energy recovery by the motor-generator.
