ABSTRACT:
An ignition current conduction time control apparatus, comprising power transistors for producing a spark for ignition at the ignition plugs, and a controller for applying ignition signals to the power transistors, wherein the saturated state of the power transistors is eliminated by controlling the start time of current conduction time of said ignition signals applied to the power transistors according to the internal resistance values of the ignition coils, thereby eliminating the heat generation of the ignition coils.
