Abstract
A method device for controlling a suction pressure of an internal combustion engine, particularly a diesel engine having an exhaust gas turbocharger. The compressor is connected to a suction line of the internal combustion engine via an actuating section having an actuating element for changing a cross-section of the actuating section. In the first step, the current suction pressure in the suction line of the internal combustion engine is determined. A compressor pressure of the compressor is determined by pressure sensors and compared to the suction pressure. Values corresponding to current operating data of the internal combustion engine are identified and an actuation signal is generated using a controller, based on the comparison; and changing the cross-section of the actuating section is adjusted by adjusting the actuating element using the actuating signals.
