Pengaruh Variasi Celah Busi dan Jenis Busi Terhadap Performa dan Emisi Gas Buang pada Mobil Bensin System Injeksi

Abstract

The mechanism of gasoline fuel motorcycle is utilizing the energy of heat gas from the combustion process in the cylinder which functions to be the working fluid and change to be energy or heat energy. It is one of the most important parts of the 4 strokes motor. To maximizing the gasoline motor performance, it needed to conduct a checking on the spark plug and notice the gap in the spark plug of the vehicle. The aims of the study were to find out the influence of the spark plug gap variations and spark plug types towards the performance and exhaust gas emissions on the gasoline car injection system. The method used in the study was the experiment method which is quantitative research, namely clearly explaining the experiment results in the laboratory towards the testing tools, and then the data analyzed using the statistics. The data collecting was obtained from the Pertalite fuel consumption measurement, the stress in the cylinder, and exhaust gas emissions on the type G15A machine using standard spark plug, double branch spark plugs, and four branch spark plugs. There were 3 types of different spark plugs by the measure of 0.70 mm, 0.80 mm, 0.90 mm; by machine rotary of 1000 rpm, 1500 rpm, 2000 rpm, 2500 rpm, 3000 rpm, 3500 rpm using Pertalite fuel for 5 minutes and 3 times repetition. To sum up, there was a significant influence of the variations in spark plug settings and spark plug types towards the performance and exhaust gas emissions on the G15A machine in the study.
