Experimental investigation on influence of metal based additives on diesel engine along with biodiesel blends

Abstract

Today 85% of the world’s energy is caused by combustion of fossil fuels, although it is the lack of fossil and emissions fuels that influence countries in particular. Biodiesel is the promising alternative form of transport to fossil fuels. Biodiesel is obtained by using from transesterification processes. In this analysis, the performance, emission and combustion characteristics CI engine fueled with B20CFME (20% Chicken Fat Oil Methyl Ester (CFME) and 80% Diesel) biodiesel was investigated. SiO2 and NiO2 metal-based additives are introduced with the B20CFME, these additives acts with the vapours of water to form a hydroxyl and minimize the oxidation temperature by reacting with the carbon atoms. Experiment was done with a Kirloskar engine at 1500 rpm with a180bar injection pressure for various loading conditions. Results reveal that, for maximum loading condition BTE, HRR, and Peak Pressure for SiO2 shows +8.2%, +2.29% and 0.54% and NiO2 shows +6.11%, 1.6%, and +0.12% than diesel respectively. Meanwhile BSFC shows −13.4% and −10.63% for SiO2 and NiO2 biodiesel blends than diesel will be noted. The exhaust emission like NOx, CO and HC decreases as the addition of SiO2 by 89.82 ppm 16.6% and 16 ppm similarly and by adding NiO2 shows reduction in the emissions by 42.8 ppm, 14.28% and 15.3 ppm than diesel will be observed.
