Abstract

This paper presents experimental performance analysis of four wheeler Liquified Petroleum Gas (LPG) car engines with different specifications. In order to normalize the performance trends among different engines with different specifications viz. bore-to-stroke ratio, cubic capacity, compression ratio, a unit parameter, power per unit displacement (Kw/Lit) was defined and calculated for each of the engines. Analysis was made over eight sample engines of the same specifications and five sample engines of different specifications. The experimental test setup involves a state-of-the-art computer controlled and data acquisition system. The comparisons of performance trends among engines are presented. This work will be useful by engine designers and researchers to understand the general performance trend of LPG four wheeler engines. Keywords: performance analysis, car engines, four wheeler, Liquefied Petroleum Gas (LPG). 1 Introduction In the present scenario, the world is facing a crisis of environmental pollution and fuel depletion. In the past few years alternative fuels are being studied by researchers as viable alternative for transportation and passenger car vehicles. Alternative fuels have benefits like better fuel economy, less pollutants and abundance at lower cost. Liquefied petroleum gas (LPG) is recently been used in the Indian Car market, as it produces low exhaust emissions as compared to gasoline. It has other benefits like low cost and fuel economy. Liquefied petroleum gas (LPG) is a by-product of natural gas processing and crude oil refining. It can consist of propane or butane or a mixture of both. LPG has the potential of producing lower CO and HC emissions due to its simple
