Abstract

A method for the cylinder-selective control of combustion processes in diesel engines. In this case, a measuring device with associated processing unit is used to detect the rotational crankshaft angle and to determine the instantaneous rotational crankshaft speed. A control device determines suitable parameters from the rotational crankshaft speed, which parameters permit a cylinder-selective equalizing or a defined unequalizing of the mean pressures in various operating ranges of the internal combustion engine, thereby minimizing the effects of component differences in the fuel feed system and the combustion system on the combustion process.
