ABSTRACT:
The invention is directed to a method for detecting combustion misfires on the basis of a first complex input feature signal wherein the nonuniformity of the rotational movement (on the basis of rpm or segment times) of the internal combustion engine is mapped within a first order defined by a rotation of the crankshaft through an angle of 720.degree./k wherein k=1. The input feature signal serves as a feature signal to detect recurring misfires and functions as a feature signal to detect sporadic misfires. The complex input signal is defined by a magnitude and a phase angle which vary as a function of time. The presence of a misfire is detected from the magnitude and the affected cylinder is determined from the phase angle.
