Abstract
The invention is directed to a method for detecting combustion misfires in a multicylinder internal combustion engine. The method includes the steps of: forming a criterion for the rough running of the engine for each cylinder individually on the basis of time intervals during which the crankshaft passes through predetermined angular ranges; and, forming corrective values from rough-running values for each cylinder individually during misfire-free operation so that the rough-running values for each individual cylinder coupled to said corrective values become equal with respect to each other.
