Analisis Pengaruh Ketinggian Jet Needle Karburator Pada Performa Motor 4 Langkah

Abstract

This research is motivated by the increasing number of motorcycle users who want better performance. In this study, testing was carried out by analyzing the effect of the height of the jet needle on power, torque and fuel consumption. This study aims to determine the effect of 1 mm, 3 mm, and 5 mm jet needle height on engine performance and fuel consumption. Based on the results of tests that have been carried out on the height of the jet needle, it is known that the height of the 5 mm jet needle has the highest power of 5.20 HP, the height of the 5 mm jet needle has the highest torque of 5.49 Nm and the need for fuel consumption in the three altitude positions has the yield at 6000 RPM rotation is less than the 8000 RPM rotatio
