Performance and Emission Characteristics of CI Engine fuelled with Pungamia Methyl Ester and it’s Blend with Diesel

Abstract
Unbalanced supply and cost escalation of petroleum fuels is a menace for diminution of renewable source of energy. The look for of alternate fuel for compression ignition engine has supposed great significance. Use of renewable biomass based fuel appears to be viable alternate with the commercial liquid fuel, predominantly for farm use. Amongst various fossil fuels for diesel, vegetable oil is a promising one based on the comparable fuel properties to that of diesel. Basically, internal combustion engines are designed to operate under conventional fossil fuel. However, the use of alternative fuel in existing engine needs modification but biodiesel can be used without any engine modification. Investigations were carried out to analyse the fuel properties of the biodiesel – Pongamia methyl ester as blend with diesel fuel from 20 to 80% by volume by running a diesel engine. Engine tests were carried out to evaluate brake thermal efficiency, brake specific fuel consumption and CO, CO2, HC, NOx emissions and smoke intensity. The outcome of the study reveals that the reduction in exhaust emissions together with increase in brake thermal efficiency and reduction in brake specific fuel consumption make the biodiesel a suitable alternative fuel for diesel fuel and environmentally benevolent.
