Abstract

The main goal of this research is to compare performance graph of engine and emission gas produced by the engine using two different type of RON which are RON 95 and RON 97. This research was use chassis dynamometer to get the engine performance result and use Emission Measurement System (EMS) to measure the exhaust gas produced. The result was shown in performance graph in the software that connected to the dynamometer machine. The result including rpm, torque and horsepower produced. Next, the EMS will shows the percentage of gasses produced in exhaust gas which are HC, CO2, CO, O2 but NOx displayed in part per million (ppm). The exhaust gasses result will show on the screen of the EMS. This research also targeted on developing the standard of procedure of fuel testing using chassis dynamometer. At the end of this research, the result will shows which type of RON fuel grade produced greater engine performance and less polluted emission gasses. Further experimental testing can be done for better result such as by using engine dynamometer that more accurate than chassis dynamometer because have less energy lost. Not only that, recommendation for further research on fuel properties also needed such as research on the element in the fuel that can affect engine performance.
