  • Method for determining a position set point of a by-pass actuator, intended for a turbosupercharger
    Patent number: 8931271
    Abstract: A method for a turbocharger of a heat engine including a turbine, a compressor, and a by-pass actuator that can be used to control an air flow that does not pass through the turbine. The method includes determining a position set point of the by-pass actuator as a function of a compression ratio set point, a compression ratio measurement, a measurement of the rate of flow through the compressor, a measurement of the pressure downstream from the turbine, a measurement of the pressure downstream from the compressor, a measurement of the temperature upstream from the turbine, and a measurement of the temperature upstream from the compressor. The method can be used to control a supercharging device with a single or dual turbocharger.

  • METHOD AND DEVICE FOR CONTROLLING SUPERCHARGING AIR OF AN INTERNAL COMBUSTION ENGINE
    Publication number: 20090217663
    Abstract: A control method including regulating air pressure prevailing in an engine intake manifold around a setpoint value. The regulating includes a slow regulation loop, a fast regulating loop, and a limitation of pressure upstream of a turbine of a supercharger. The supercharging pressure limitation is implemented when the pressure upstream of the turbine exceeds a predetermined threshold value.
