Description
Summary:The chief criterion for non commercialization of biodiesel is the unbalanced fuel properties and poisonous NOx emission level in elevated quantity. But in the case of marketable petrol and diesel fuels, the fuel properties are in much steady state leading to extended fuel stability without putrefying in fuel properties and lower NOx emission level. The difference between the stability capacities is the reaction of fuels to the atmospheric oxygen. Obviously biodiesel contains oxygen content in superior quantity, as the feedstock is the naturally available resources when compared to fossil fuels. The present attempt has been focused to stable the fuel properties by evaluating the oxidation, storage and thermal stability of Alexandrian laurel and Poison nut biodiesel with the assist of Tert-butyl hydroquinone antioxidant at 1000 ppm, in the subsequent ratios as AP10T, AP15T, AP20T, AP25T and AP30T using high-tech equipments. FTIR infers the stability variation with the aid of C–H and O–H bonds in the fuel blends. In adding up with that, the relationship between NOx emission and cylinder head temperature has been made through novel Fluke thermal imager. As a result, AP20T shows supreme fuel stability and NOx emission nearer to commercial diesel fuel.
