Abstract
An ignition controller has a revolution rate detector, a crankshaft angle detector, a computer, a first read/write memory device for the computed ignition angles for all cylinders, an ignition cycle overlap detector, a FIFO memory for storing a computed ignition angle and a copier for copying the angle from the first memory to the second depending on the degree of overlap. An ignition output device outputs the ignition angle for the next cylinder to be ignited and the corresponding charging time and charging starting angle.
