Performance and Emission Characteristics of CI Engine Fuelled with LPG and Pure Diesel

Abstract

This paper presents observations, results and their analysis with respect to the experiments conducted on fuel mix used in a set up on CI engine. LPG air mixes have been used in the air intake manifold at different concentration level while the diesel injection through injector at the end of compression stroke has remained undisturbed at the original level. The experiments were conducted at different loads. The objective of the study has been to minimize the pollutant emission. Observations were also taken for the impact on thermal efficiency and the power developed. Results have shown an all round favourable impact of LPG injection. Further; prospects of optimisation have been indicated on which the experiments have been initiated.
