Influence of Graphene Nano Particles and Antioxidants with Waste Cooking Oil Biodiesel and Diesel Blends on Engine Performance and Emissions

The main reason for the limited usage of biodiesel is it tends to oxidize when exposed air. It anticipated that addition an antioxidant along with graphene nano particle improves combustion diesel-biodiesel blend. In present research made from transesterification waste cooking oil used. Three synthetic antioxidants butylated hydroxytoluene (BHT), 2(3)-t-butyl-4-hydroxyanisole (BHA) and tert butylhydroquinone (TBHQ) 30 ppm were added at a volume fraction 1000 diesel–biodiesel blends (B20). performance emission tests performed constant engine speed 1500 rpm. Because inclusion particles, surface area ratio fuel augmented enhancing mixing ability chemical responsiveness during burning causing superior performance, aspects compression ignition engine. results revealed there was slight increase in brake power thermal efficiency about 0.29%, 0.585%, 0.58% 6.22%, 3.11%, 3.31% B20GrBHT1000, B20GrBHA1000 B20GrTBHQ1000, respectively, compared B20. Additionally, BSFC, HC NOx emissions reduced considerable levels reformed fuel.
