Gasoline engine multi spark ignition system

This paper is to develop the ignition system in spark plug of gasoline engine ignition by increase the sparking pulse at spark plug in one cycle which start form the before top dead center of the engine pistol to the position that the pistol of the engine come to the bottom dead center. So applying of ignition system has four sparking at spark plug in one cycle of each one stroke. This paper divided two parts for working. Past One is simulation to divide pulse signal that consist of continued pulse signal and selection pulse signal to spark in each one stroke. Part Two use encoder to measure cycle of engine that cooperation with engine CPU by working instead of distributor for choose pulse signal to each one stroke. Pulse signal width of each one stroke is depend on the Dwell angle, so the width of pulse signal is divided the stroke ignition of each one stroke by CPU working divide one pulse signal to be four pulse signal and transfer this pulse signal to drive coil ignition.
