Abstract
At higher engine speeds the ignition time is advanced by decreasing the time between the breakdown of a threshold element which breaks down for a predetermined amplitude of voltage across the primary winding of the ignition coil and the furnishing of the signal which causes interruption of the primary current. The time is shortened either by decreasing the time constant of the timing circuit connected to the threshold element, or by switching a second timing circuit having a shorter time constant into the circuit at higher engine speeds.
