| 摘要 |
<p>The invention relates to a method for controlling a suction pressure (P3) of an internal combustion engine (1), particularly a diesel engine, having an exhaust gas turbocharger (9), the compressor (12) of which is connected to a suction line (3) of the internal combustion engine (1) via an actuating section (10) having an actuating element (20) for changing a cross-section of the actuating section (10), comprising the following process steps: determining the current suction pressure (P3) in the suction line (3) of the internal combustion engine (1) and a compressor pressure (P2) of the compressor (12) by means of pressure sensors (24, 25); comparing the determined current suction pressure (P3) and compressor pressure (P2) to target values corresponding to current operating data of the internal combustion engine (1) by means of a controller (16), and generating an actuation signal using the same, based on the comparison; and changing the cross-section of the actuating section (10) by means of adjusting the actuating element (20) using the actuating signals generated by the controller (16) as a function of the current suction pressure (P3), compressor pressure (P2), and the current operating data for controlling the suction pressure (P3) of the internal combustion engine (1), and a corresponding device.</p> |
