Background/Objectives: This research analyzes waveforms of surge and discharge voltage in the plasma ignition and point ignition through realization of plasma spark by self-producing a plasma generator apparatus. Methods/Statistical Analysis: The components including batteries, ignition pulse generator (self-produced), pencil type ignition coil, iridium ignition plug, and nonresistance ignition plug were used in the experimental device. The experimental method involved assessing the gap change of the ignition plug and the engine rotation count by setting the range of measurement from 1,200 rpm to 5,200 rpm. By connecting an additional device, impedance value increased due to the influence from the internal elements and components. Findings: The plasma ignition discharge energy discharges plasma completion from 0.75 to 1.5 ms to show that the point and plasma have different energy characteristics and when the ignition plug gap is increased, the energy characteristics of discharge voltage increased. However, the starting point of the discharge responded 2.5 ms faster compared to the point ignition due to the plasma discharge point delay of 0.75 compared to the point ignition. By connecting an additional device, impedance value increased due to the influence from the internal elements and components. This helped to find the cause behind the relatively delayed 3rd phase amplification’s plasma discharge starting point in comparison to the point ignition. Application/Improvements: We believe that better result will be drawn when the electrode diameter and formation are re-engineered with the optimized volume change of plasma produced between the ignition plug electrodes.
