Abstract
The invention is directed to a method for detecting combustion misfires in a multi-cylinder internal combustion engine, the method comprising the steps of: determining the rough-running values for the engine individual to the cylinders; determining a quantity for the level of a subset of the rough-running values; forming a reference value by logically coupling the quantity with an offset; and, comparing the rough-running values to the reference value and evaluating a passthrough of the reference value as a misfire.
