Estimating the term…
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.
1-22. (canceled)
A method for closed loop controlling the characteristic values of combustion in an internal combustion engine with at least one control path, wherein a rapid control path, which can act and measure on each injection, takes into account an actuating behaviour of a slow control path, which in a time pattern requires a much longer time than the rapid control path, and in that the repercussions on characteristic values of combustion and/or changes of at least one characteristic value of the rapid control path are calculated directly from an extent of the deviation between the actual values and the target values of the slow control path.
