An analysis of the smoke output of a CI engine running on B10 novel algae biofuel with and without DEE additive and clean diesel as fuels

Abstract

Aim. The aim of this study is to analyze and compare the Smoke Opacity of compression ignition (CI)  Diesel engines fueled with novel blend Algae oil with diesel biofuel blend with and without the Diethyl ether (DEE) additives. Materials and Methods: TheAlgae oil is obtained from microalgae through mechanical pressing and transesterification process which is then blended with diesel in the ratio of 10% and then added with 5% DEE additive termed as D85B10DEE5. A single-cylinder Kirloskar engine mounted with an eddy current dynamometer is used in this investigation. The Smoke Opacity of CI engines is studied for both biofuel blends (D90B10) and D85B10DEE50 fuels. For each fuel, 20 experimental trials are considered based on a G-power calculator with 80%  power and the alpha value of 0.5 under 95% confidence interval (CI). Result: Smoke opacity produced for diesel -10.7 ppm and D90B10 -9.51 ppm and the best blend produced was D85B10DEE5 -9.17 ppm. The significance level obtained among the group was 0.001 which was less than 0.05 ( p<0.05) which shows that there was a significant variant among the considered fuels. Conclusion Within the limits of the study it is found that the Smoke Opacity for D85B10DEE5 was lesser than the D90B10 fuel blend.
