General-purpose high effective electronic ignitor

The utility model relates to a general-purpose high effective electronic ignitor which is composed of an oscillator A, an interface circuit B, a fore-stage impelling circuit C and a rear-stage power switch circuit E. A diode D is bridged between the collector electrode of the transistor (BG) of the interface circuit B and the hot end of a breaker Kf. So the utility model can provides more sparking so that mixed gas is completely burnt. The utility model has the advantages of high reliability, convenient maintenance, oil saving, easy starting for a vehicle, good acceleration performance, no special ignition coil, no special distributor engine power increasing and less exhaust emission pollutant, and is suitable for various gasoline engine automobiles.
