The objective of this study is to determine the Research Octane Number (RON) of Liquefied Petroleum Gas (LPG) using a Cooperative Fuel Research (CFR) engine. In order to do this, a series of modifications were carried out on the engine components including piston and fuel feeding system prior to the experiments. The experiments were conducted on a wide range of LPG fuel compositions, consisting of various volumetric ratios of propane, iso-butane, n-butane, and trace amount of olefins to determine the RON of LPG using the well-documented bracketing method accepted by the American Society for Testing and Materials (ASTM). A mathematical model for variation of LPG research octane number with the volumetric ratios of consisting gaseous fuels was also developed.
