establishment of the rules of the individual cylinders of a brennkraftmaschine supplied fuel

摘要

A device for controlling and regulating a diesel engine, with a base controller (7) to which performance quantity signals of the engine are fed and an output signal of the base controller is used for driving an electromechanical final controlling element for the fuel and/or air quantity, with a rotational-speed calculator (8) for calculating a cylinder-specific rotational speed (n1) and a mean engine speed (), with a comparator unit (10) for outputting positive or negative alteration values ( DELTA Qi) for each cylinder if the cylinder- specific rotational speeds (ni) lie below or above the mean rotational speed (), with a correction value memory (18) with z cylinder memories (18-i) for cylinder-specific correction values ( DELTA RWi), to which the alteration values ( DELTA Qi) can be fed, and with a cylinder selection unit (24) for outputting the correction values. A drift compensator (31), to which the cylinder-specific correction values ( DELTA RWi) stored in the cylinder memories (18-i) are fed, is set up to form a mean value of the correction values and has subtracting elements (34-i) which are connected upstream of each input of the correction memory (18) and to which, on the one hand, each cylinder- specific alteration value ( DELTA Qi) determined in the comparator unit (10) and, on the other hand, a mean value of the correction values is in each case fed.
