Abstract

A device for controlling and regulating a diesel engine, with a base controller (8), to which performance quantity signals of the engine are fed and an output signal of the base controller is used for setting the fuel and/or air quantity, with a rotational speed calculator (9) for calculating a cylinder-specific rotational speed (ni) and a mean rotational speed signal () with a comparator unit (11) for outputting alteration values ( DELTA Qi) for each cylinder if the cylinder-specific rotational speeds (ni), are below or above the mean rotational speed (), with a correction value memory (19) with z cylinder memories (19-i) for the cylinder-specific correction values, it being possible for the alteration values ( DELTA Qi) to be fed to the cylinder memories (19-i). Each cylinder is allocated its own final controlling element for the fuel quantity, the output signal of each cylinder memory (19-i) together with the output signal of the base controller (8) being fed in each case to a control unit (3-i) for the allocated final controlling element, each cylinder memory (19-i) having k working- point-dependent memory areas (19-ij) and a memory-area selection unit (18) allocating the input and output of each cylinder memory (19-i) to a selected memory area or selected memory areas as a function of the mean rotational-speed signal (n) and/or other performance quantities according to a predetermined selection characteristic via an allocation unit (23-i, 24-i; 31) controlled by it. <IMAGE>
