ABSTRACT:
This method is intended for a turbocharged internal combustion engine having an electrically controlled throttle valve. The turbocharger has a waste gate for regulating its pressure. The position of the valve and the extent to which the gate is open are controlled according to two distinct modes of operation. In the first mode, the position of the valve is predetermined as a function of engine control and operating parameters, and the position of the gate is used to regulate the air flow rate. In the second mode, the extent to which the gate is open is predetermined as a function of engine control and operating parameters, and the position of the valve is used to regulate the air flow rate. Which mode is used is gauged by an electronic device which chooses the mode of operation to be implemented as a function of predetermined conditions stored in memory.
