Summary:

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 lieu of global climate change and rising earth's average surface temperature, it is essential to control emissions produced by the diesel engines. There are many ways to achieve the aforesaid goal, viz., by modifying the engine design features, functional parameters, installing exhaust treatment devices, using alternative fuels, et cetera Changing the engine design is quite complex and is possible to a certain extent only. Lately, alternative fuels have gained a lot of interest among researchers to improve the performance and reduce the exhaust emissions of engine. These fuels would also cater to the alarming situation of depleting fossil fuels. In the current study, efforts have been made towards improving performance and reducing the emissions simultaneously. 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. Earlier researches have shown that oxygenated blends, due to having a relatively higher content of oxygen, tend to improve the combustion characteristics in an engine. 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 VCR Engine with a standard CR of 17:1 and Injection Pressure of 200 bar for five loading conditions, id est, no load, 25%, 50%, 75% and 100% load conditions. The BTE, BSFC and emissions of smoke, HC, CO and NOx gases were measured, analysed and presented for the existing engine in this paper
