Abstract
An electronic circuit device for ignition pulses for an i.c. engine having a two- or three pole magnetic system generating positive and negative pulses. One of the pulses is used for ignition energy and the other for power supply of electronic equipment. As a reference point for ignition advance calculation is the peak of said power supplying pulses used. An oscillator (36) supplies a pulse frequency many times higher than the r.p.m. of the engine. A peak detector (14) and said oscillator are connected to a pulse counter (39) which after a predetermined number of pulses from the reference point releases a trigger pulse for the ignition energy. A logic unit (12) sets the counter on the predetermined number in dependence of the r.p.m. of the engine.
