Abstract: The invention relates to a method for closed loop controlling the air system in an internal combustion engine, in particular a diesel internal combustion engine with a first actuating element for recirculated exhaust gas in the exhaust gas recirculation tract and a second actuating element for air in the inlet tract, the two actuating elements being adjusted as a function of each other. In order to increase the quality of closed loop control, provision is made for each actuating element to be controlled separately by its own respective controller, each controller being optimally configured for the respective controlled system, and a target value being provided for each controller.

Abstract: A discharge region of a centrifugal compressor is provided. A scroll casing is asymmetrically formed in a circumferential direction and configured to be positioned in different angular positions in the circumferential direction. A vaned diffuser is configured to be positioned in different angular positions in the circumferential direction. The vaned diffuser includes a plurality of guide elements configured to be arranged in a distributed manner in the circumferential direction. Means are provided for positioning the vaned diffuser with regard to an angular position of the asymmetrically formed scroll casing. An angular spacing of two guide elements which are arranged adjacently to each other differs from an angular spacing of two other guide elements which are arranged adjacently to each other. By varying the angular spacings between two adjacent guide vanes of a diffuser along the circumference, the resonance vibration of the compressor can be reduced.

Abstract: The nozzles are in the form of blowing-in openings in the housing wall which bounds the flow channel. The blowing-in openings are fed directly by means of air which is extracted from the flow channel downstream from the diffusor. This air is at a higher pressure than the flow in the flow channel upstream of the diffusor. This results in a passive, dynamic stabilization system for a compressor stage in the high pressure-ratio range, which does not require any additional control or actuating elements.

Abstract: A method of regulating or controlling a cyclically operating internal combustion engine using a computation model by which the cycle or portions of the cycle of the internal combustion engine is, or are, divided into individual parts and the operating condition within each cycle part is determined using measured values, stored and/or applied data in order to obtain actuating variables for operating the internal combustion engine. The time limits of the cycle parts are at least partially calculated as a function of at least one variable engine operating parameter. The operating status of an internal combustion engine can thus be determined readily and quickly while still with sufficient accuracy so as to obtain actuating variables suited for regulating or controlling the internal combustion engine using electronic control units available for series operation.
