Abstract
This paper presents the results of an investigation on the performance characteristics of a small spark ignition (SI) engine fueled by liquefied petroleum gas (LPG) to be compared with gasoline fueled. The LPG delivery systems used was fuel injection while carburetor was used for gasoline. In the experiment, wide open throttle (WOT) was run on a four stroke single cylinder engine that was coupled to a 20 kW generator dynamometer to measure the engine performance such as engine torque, and fuel consumption. Others parameters included are brake power (BP), brake specific fuel consumption (BSFC) and brake thermal efficiencies (BTH). The results were compared, analyzed and suggestions were made for modification for further improvement of using LPG in a small SI engine. It was found that the engine fueled by LPG had a lower performance compared to the gasoline fueled engine.
