ABSTRACT:
An electronically controlled ignition system is provided in which the point in time at which the primary current flowing through the primary winding of the ignition coil starts, is controlled as a function of speed so that the said primary current only reaches the value required for ignition just before the ignition time and in which immediately before the ignition time, it is ascertained whether the primary current has reached the value required for ignition, wherein if there is no primary current or insufficient primary current to prevent ignition during periodic fluctuations in speed, the electronic control arrangement is switched off for a fixed period and the time at which the primary current is used is derived directly from the control signal of the ignition pulse generator and in which, once the switch off period has come to an end, continuous and automatic electronic control is reinstituted.
