Abstract

PURPOSE:To improve the fuel consumption by placing a movable contact for switching in the firing energy charging capacitor for a plasma igniter thereby reducing the power supply to the firing plug in the high speed area where the firing combustionability is good. CONSTITUTION:When the rotation of the engine is lower than 2,000rpm, for example, the movable contact Sm of each cylinder is held to S1 side while under the state where the capacitor C1 is charged with high voltage the signal (a) from the firing trigger signal genrating circuit A is brought to H and upon turning on of SCR1 the high voltage high energy power is supplied to the plug P1 to fire reliable. When the rotation exceeds over 2,000rpm, Sm is turned to S2 side while upon turning on of SCR1 by the trigger signal (a) approximately 20% of the high voltage high energy of C1 is fed to the capacitor C2 and small energy of approcximately 0.1J is injected through a booster transformer T1 to the plug P1. Since the density of the mixed gas is high, the firing combustion is performed well even with the small energy.
