PURPOSE:To provide a method to restore the output, rate of fuel consumption and exhausting performance to their original specified performance by regenerating the optimum ignition voltage, removing carbon and gums attached to the inside of cylinder by high fuel energy, by cleaning inside the engine and by eliminating variation in the cylinders. CONSTITUTION:A circuit composed of a resistance 12, gas discharge tube 13 and capacitor 14 is additionally installed in parallel with exciter contact circuits 10, 11 set in series to the primary winding 2 of an ignition coil 1. The electroconductivity of the ignition circuit is recovered by changing the voltage waveform on the primary side of the ignition coil so as to have a good rising and falling characteristic, whereby also harmful substances are removed out of inside the engine. Circuits of abovementioned resistance 12 and gas discharge tube 13 absorb the counterelectromotive force, generated when the contact breaker 10 is off, at a high speed. Thereby no voltage exceeding a certain specified value will be impressed to the exciter contact circuits. |
