PCT No. PCT/DE94/00675 Sec. 371 Date Dec. 26, 1995 Sec. 102(e) Date Dec. 26, 1995 PCT Filed Jun. 18, 1994 PCT Pub. No. WO95/00755 PCT Pub. Date Jan. 5, 1995A method for testing a spark-ignited internal combustion engine is proposed, wherein a pulse-shaped signal derived from the ignition system is made available which signal allocates a pulse (34, 34a, 34b) to each switching process occurring in the ignition system. A first pulse (34) of a pulse group (32, 33) of the signal respectively starts a retriggerable timer (16) which, during its active phase (TA, T'A), suppresses the pulses (34a, 34b) of the pulse group (32, 33) following the first pulse (34). The time to be predetermined for the retriggerable timer (16) must be predetermined such that it is longer than the maximum interval (T1, T2) between the pulses (34, 34a, 34b) of a pulse group (32, 33). The method according to the invention is particularly suitable for testing a spark-ignited internal combustion engine which is provided with an ignition system comprising a spark band ignition.
