Experimental investigation of performance and emissions of CRDI engine fuelled with kapok ester oil blended with diesel

As world oil reserves is going down rapidly and the world energy demand is going up, along with the increasing Greenhouse emission, we need to support the initiative by minimizing the emission and maximising the efficiency. We need to grow awareness among people of the importance of Biofuels which will be one of the energy source in the near future. This paper deals with fuel of kapok-Ester oil and Diesel oil blend in the Proportional of (10% of kapok-ester oil and 90% of diesel oil) and B20 (20% of Kapok-ester oil and 80% of Diesel oil). The properties of the blended fuel were measured according to the ASTM standards. The Experiment setup includes of single cylinder four stroke CRDI diesel engine with varying load at constant speed. The experiment results show that increasing the Kapok-ester oil proportion increases the brake thermal efficiency, decrease CO and increase the NOx emission.
