Improvement Physicochemical Properties of Fuel and Emission Reduction from Diesel Engine

In this study¡ with added nitrogenated and metal based additive to standard diesel fuel¡ physicochemical properties of fuel and emission of exhaust gas from diesel engine were investigated. Nitromethane and manganese oxide were selected as nitrogenated and metal based additive¡ respectively. Nitromethane blended with diesel fuel 10% in volume¡ and 100 mg of MnO2 added per kg of diesel fuel. The experimental tests were carried out on ECE R-96 8modes. The results showed that by increasing additives cetane index ¡viscosity would be decreased contrast with sole diesel. These tests were measured according to ASTM D 976 and ASTM D 445¡ respectively. On the other hand¡ the density which was measured according to ASTM D 1298 did not change significantly. Besides¡ exhaust emission¡ such as¡ smoke concentration for fuel with nitrogenated additive 25% and metal based additive 16% would be reduced. In general low BSSOOT emission was measured with these additives.
