Investigating the influences of liquid LPG injection on spark ignition (SI) engine

Abstract

Liquefied petroleum gas (LPG) is one of the alternative fuels that becoming popular to be use in spark ignition engine (SI). This paper briefly presents the influence of energy content to the engine output of 1.6L SI engine of Proton Gen 2. The engine was coupled to a chassis dynamometer and few related apparatus were employed in determine the engine behavior. All data collected were illustrated in graph for further analysis. The engine shows comparable engine output, however, the engine requires some tuning in order to fully utilize the energy content of LPG.
