The use of Compression Ignition engines due to higher thermal efficiency and better fuel economy has increased many folds as of late. However, diesel fuelled engines are known to have higher smoke and NOx emissions compared to their counterparts. In the current study, efforts have been made towards improving performance and reducing the emissions simultaneously by modifying the fuel. Two oxygenated additives, namely 2-Ethoxyethyl Acetate (EEA) and Nitromethane (NM) were added to the diesel fuel in different proportions (v/v %) to form ternary blends. In current study, performance was evaluated with different blends viz., D-EEA5-NM2 (93% Diesel, 5% 2-Ethoxyethyl Acetate, 2% Nitromethane), D-EEA10-NM2, D-EEA15-NM2, D-EEA20-NM2 and was compared with that of pure diesel. The experiments were carried out on a Diesel Engine with a standard CR of 17:1 and Injection Pressure of 200 bar for five loading conditions, i.e., 0% (no load), 25%, 50%, 75% and 100% load conditions.
