Numerical Study of Combustion Characteristics, Performance and Emissions of an SI Engine Running on Gasoline, Ethanol and LPG

Abstract

A numerical study has been carried out to determine the combustion characteristics, engine performance, and emissions of a spark-ignition (SI) engine. In this work, a four-cylinder, four-stroke indirect injection engine fueled with gasoline, LPG, and ethanol was used. The results were collected at a constant engine speed of 2500 rpm with variable compression
