PURPOSE:To increase a force per explosion by a method wherein a plurality of pulses of electric discharge are supplied to the particles of combustible substance in a cylinder to increase the source of ignition. CONSTITUTION:A movable arm 50 for supplying electricity is advanced in an insulating tube 52 against the resilient force of a coil spring 53 in accordance with a revolving speed under utilizing a centrifugal force for the movable arm 50, which is generated in accordance with the increase of the revolving speed, and an angle of the electric discharging is widened to begin an angle advancing effect from a point where the part 55 of the electric discharge at the tip end of the tube 52 is coincided with the opening part at the same end substantially. Receiving electrodes 56, which are receiving the effect of electric discharge, are arranged with equal intervals in the same number as the cylinders of the electric ignition type engine through insulating parts and are connected by lead wires 7 to ignition plugs 6 mounted on each cylinders. According to this method, the beginning and the finishing of the electric discharge are coincided with each other in the same axial direction and the effect of the electric discharge may be continued, thereby increasing the force of explosion. |
