Abstract
A fuel injection and ignition control system for a two-cycle crankcase compression engine wherein both fuel injection and ignition timing are controlled by sensed engine running characteristics at a predetermined crankshaft position. The timing of the ignition is controlled by the same parameter at which the fuel injection was controlled, so that the timing of ignition and amount and duration of fuel injection will be optimized for the same engine running condition.
