PURPOSE:To improve a combustion efficiency and to reduce a production amount of noxious gas, by a method wherein a plurality of ignitions are conducted during one cycle of an engine, and the ignition is performed in inverse proportion to a rotation speed of the engine. CONSTITUTION:The output voltage of a signal generator 1 equipped with a contact breaker 10, which makes and breaks circuit in proportion to the number of revolutions of an engine, is wave-form-shaped by means of a wave-form-shaping circuit. A pulse voltage is generated from a pulse generating circuit 4 corresponding to the oscillation output voltage of an oscillation circuit 3, and actuates a switch circuit 6 through a gate circuit 5. The operation of the switch circuit 6 causes a spark generation circuit 7 to generate sparks by the discharge from a charging circuit 8. |
