Abstract (en)
[origin: EP0443175A2] The invention relates to an ignition system for internal combustion engines, having a crankshaft signal generator (KW signal generator) which supplies per crankshaft rotation a reference mark assigned to a specific crankshaft angular position and having a phase signal generator, in particular a camshaft signal generator (NW signal generator) which within two crankshaft rotations generates a number of phase signals assigned to the camshaft position, which number corresponds to the number of cylinders of the internal combustion engine, one of the phase signals being used to form a cycle signal which characterises the start of an ignition cycle. In order to be able to constantly perform a reliable cylinder identification (cylinder 1 recognition) in emergency operation occurring in the event of a failure of the KW signal generator, an identification signal (K) which forms the cycle signal (Z) together with the associated first phase signal (P) is applied between a first phase signal (PE) assigned to a specific cylinder (cylinder 1) and the adjacent phase signal (P) which follows said signal. <IMAGE>
