Abstract (en)

[origin: WO2004099594A1] The invention relates to a turbocharged internal combustion engine comprising an electrically controlled butterfly valve. The turbocharger is fitted with an outflow valve for regulating the pressure thereof. The position of the butterfly valve and the opening of the outflow valve are controlled according to two separate operating modes. In the first operating mode, the position of the butterfly valve is pre-determined according to engine control and operation parameters and the position of the outflow valve ensures the regulation of the airflow. In the second operating mode, the opening of the outflow valve is pre-determined according to engine control and operation parameters and the position of the butterfly valve ensures the regulation of the airflow. The two operating modes are controlled by an electronic device which selects the operating mode to be used according to stored pre-determined conditions.
