Experimental investigation on the performance and emission characteristics of CI engine using waste cotton seed biodiesel with ZNO as a fuel additive

Abstract

The energy crisis created by depletion of fossil fuels and the toxic emissions from the fossil fuel demands for eco-friendly potential alternative sources of energy. Even though unclean, biodiesel is found to be a potential alternative for the fossil fuels. In the present work, the emission characteristics and performance of biodiesel blend with and without ZNO additive was studied. There are four biodiesel blends studied in the first part of the research and found that the B25 combination gives a better result compared to others; therefore, this blend is tested with three proportion of ZNO additive in the second part of the research. The addition of 125 PPM of ZNO to the selected B25 blends gives a better performance, the efficiency improvement is found to be 4.2% and the emission of NOx is by 10.3% under full load condition.
