Abstract
A process for controlling a piston internal combustion engine by maintaining a running limit thereof. The process includes the steps of: detecting in at least one cylinder, over at least one work cycle and without reference to a crankshaft position of the engine, a measured variable which is influenced by a conversion of fuel into energy; setting the measured variable in relation to a detected, stored measured variable of at least one previously intercepted work cycle; and producing an adjusting signal from any deviation between the measured variables for inputting the adjusting signal to an engine regulation system. The measured variable can be either a pressure course, a light intensity or an ion current corresponding to the combustion process within the engine.
