Abstract
Experimental investigation was carried out to analyse the combustion, performance, and emission characteristics of DI diesel engine using selective biodiesel–diesel–ethanol mixture or diestrol fuels. Eleven diestrol fuels were selected on the basis of good miscibility, calorific value, and clear appearance based on the stability test carried out at different temperatures from 40 °C to 10 °C. The engine was made to run under varying loads at a constant speed of 1500 r/min. The results revealed that the maximum heat release rate of diestrol fuel was 7.5 per cent lower than that of diesel, while the cylinder gas pressure was nearly close to that of diesel fuel at 100 per cent load condition. A shorter ignition delay of 12.8° CA was observed with diestrol fuel consisting of 30 per cent biodiesel 60 per cent diesel and 10 per cent ethanol, which was 1.9° CA higher than biodiesel and comparable to that of diesel. Maximum brake thermal efficiency of 29.91 per cent was observed for diestrol fuel. While using diestrol and biodiesel, nitric oxide (NO) and smoke emissions were lower than that of diesel at all the load conditions.
