PCT No. PCT/DE82/00034 Sec. 371 Date Sep. 29, 1982 Sec. 102(e) Date Sep. 29, 1982 PCT Filed Feb. 24, 1982 PCT Pub. No. WO82/03685 PCT Pub. Date Oct. 28, 1982.A method is disclosed for the recognition of irregular combustion processes in an internal combustion engine. In this method, a parameter characterizing the course of combustion-for example, pressure, light in the combustion chamber, sound and the like-is detected by means of a sensor, and the sensor signal is integrated within a predetermined crankshaft angle range or time interval of the combustion cycle and compared with a signal integral obtained in a previous cycle. The signal integrals of cycles directly following one another are compared, and monitoring is performed as to whether a signal increase above a predetermined threshold is occurring, in the case where combustion has heretofore been regular, or the signal is decreasing by more than a predetermined amount, in the case where irregular combustion has been taking place. In the first case, the result is the recognition of irregular combustion; in the second case, the result is the recognition of the end of the irregular combustion.
