ABSTRACT:
A voltage distributor for a spark ignition internal combustion engine. The distributor supplies voltage to spark plugs in a sequence corresponding to the firing order of the engine. The distributor is not driven by the camshaft of the engine in the conventional manner, but rather uses steering logic and a decoder in conjunction with a multiple position switch and trigger pulses to produce the voltage distribution. The steering logic and decoder may comprise a stepper motor and stepper motor decoder circuit operated by trigger pulses to produce rotation of a rotary switch or, alternatively, may comprise a binary counter and associated decoder for controlling relay switches.
