The Analysis of the Exhaust Gas & the Ignition Secondary Wave Shape According to the Change of the Ignition Plug Electrode Gap Size and Engine RPM

The efficiency of the automobile is relative to the structure and a special quality of the engine, the quality of the fuel, the electronic control system and the ignition device etc. The automobile of recent times is achieving the engine performance and the high ratio of fuel and air, with to accomplish a high energy ignition device. For complete combustion and combustion activation of the mixture the ignition energy of high voltage is necessary. In order creates the flame which is powerful in the combustion mixer by high voltage ignition energy, the structure and efficiency of the ignition plug must be improved. The mixture(air/fuel) is ignited by the flame which occurs from between the electrode of the ignition plug, and the ignition peek voltage and combustion form are decided according to size of the electrode gap. The ignition plug which is used in ignition system of high voltage is using the electrode gap of about 1.1mm degree. This size of electrode gap becomes the important element to control an ignition efficiency. The goal of the paper is to research the change of the exhaust gas consistency and change of the ignition secondary wave shape according to the ignition plug electrode gap size and engine RPM.
