ABSTRACT:
A method for varying the phase spacing of sequential ignition control pulses emitted by an ignition pulse transducer and an apparatus for performing the method are proposed, wherein it is ascertained in the case of the sequential ignition pulses whether their phase spacing has become shorter. If a shortening of the phase spacing is ascertained, then the ascertained phase difference, or a maximal value of the phase difference, is added to the phase spacing of the ignition pulse at that particular time. In this manner, jerking which occurs particularly at constant rpm, when internal combustion engines with externally-supplied ignition used to operate a motor vehicle are driven in the vicinity of the idling rpm, is avoided by simple means.
