Impact of antioxidants on NOx emissions from a mango seed biodiesel powered DI diesel engine

The uses of biodiesel in diesel engines result in reduction of exhaust emissions, though many researchers described that the biodiesel produces higher NOx emissions than diesel, which is detract from the inflation of the market for these fuels. The aim of the present study was to analyze the experimental exploration of the three antioxidants DEA (Di-Ethyl Amine), PHC (Pyridoxine Hydro Chloride) and TBHQ (Tert Butyl Hydro Quinone) on engine emission and performance of a single cylinder diesel engine fueled with methyl ester of mango seed. The experiment is conducted with different antioxidant concentrations of mango seed methyl ester mixtures (100, 250, 500 and 1000 ppm). The results exhibited that PHC is effectual in controlling NOx emissions than TBHQ and DEA. (C) 2015 Faculty of Engineering, Alexandria University. Production and hosting by Elsevier B.V.
