Abstract

The performance of a 4-S, single cylinder air-cooled Kirloskar diesel engine operating with different blends of diesel-honge oil combinations has been studied. The study is focused on the exhaust gas parameters like temperature and percentage of carbon in the emissions. Based on the preliminary experiments and available literature on engines using pure diesel, a mathematical model adoptable for computer simulation has been formulated for calculation of output characteristic parameters like exhaust temperature, w% carbon in exhaust and speed of the engine as well as the break power generated by the engine from input parameters of load on the engine and the fraction of honge oil in the diesel-honge oil blend.

The computer simulation model has been found to be able to predict the actual behaviour of the diesel engine with blended fuels with within 5% accuracy in the whole range of blending from 0.0 to 1.0, The computer simulation model can be adopted for different blends in engines working on Diesel or Otto cycles using combinations of petrol, diesel, Jetrropha, Honge or other oils, and is expected to facilitate use of bio-fuels in transport and other industries with minimum experimentation
