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.

Highlights

Liquefied petroleum gas (LPG) is a clean fuel and known as “Autogas”
LPG is one of the alternative fuels that received much attention as a replacement of traditional fuels due to their economical costs, high octane numbers, high calorific values, availability in large volume and lower polluting exhaust emissions The usage of LPG especially in spark ignition engine (SI) engine has broadly been used in a few countries such as Italy, Turkey, Russia and Korea [1]
It’s provides better cold start performance in gasoline engine because its rate of vaporization is very fast during the intake stroke and the amount of homogeneous mixture in the combustion chamber is substantially increased [3,4,5,6]

Summary

Introduction

LPG is a clean fuel and known as “Autogas”. LPG consists of a mixture of propane (C3H8) and butane (C4H10). LPG is one of the alternative fuels that received much attention as a replacement of traditional fuels due to their economical costs, high octane numbers, high calorific values, availability in large volume and lower polluting exhaust emissions The usage of LPG especially in SI engine has broadly been used in a few countries such as Italy, Turkey, Russia and Korea [1]. The usage of LPG as alternative fuel especially in gasoline engine gives many advantages especially in reducing dangerous knocking phenomena while running the engine at the medium high load condition and offers better exhaust emissions production [2]. It’s provides better cold start performance in gasoline engine because its rate of vaporization is very fast during the intake stroke and the amount of homogeneous mixture in the combustion chamber is substantially increased [3,4,5,6]. Excessive enrichment of the air-fuel ratio at low coolant temperature is discarded
