Diesel engine contributes the most in the field of automobile, agriculture, construction and power generation, Due to serious environmental problem and rising cost of diesel, lot of research work is going on to replace conventional source of energy by a renewable source of energy. Diesel engine cannot be replaced because of its efficient performance at higher power and reliability with alternative engines. Diesel engines emissions contribute the most in the environmental problem, which is causing serious health problems for humans. The major emissions are smoke and NOx which need to be controlled in an effective manner. To find out the suitable additives to reduce exhaust emissions an enhance performance of CI engine, this experiment was carried out. For this purpose, detailed experiments were conducted with different sets of diesel–2–methoxy ethyl ether–nitromethane blends. Mixing of 5% MXEE and 2.5% NM with 92.5% diesel on volume basis (D–MXEE5–NM2.5) showed optimum results of emission and performance. Compared to the fuel mixture D-MXEE5-NM2.5 with diesel, an increase in BTE was found to be 4.90% and a decrease in smoke by 25.28%. However NOx increased by 17.94%.
