Rapid depletion of petroleum reserves and the environmental pollution caused by the growing use of conventional fuels created a challenge before the world that new type of fuels should replace the conventional fuels to achieve the future emission regulations. Hence great deal of research effort has been focused to find alternative fuel. The consideration of oxygenates with diesel fuel is a recent approach receives great attention in reducing the exhaust emissions of an engine The combustion, performance and emission characteristics of diesel fuel and oxygenated blends with diesel are analyzed in a four stroke naturally aspirated single cylinder direct injection compression ignition engine. The additives include 2-Ethoxyethanol (2EE), DiethyleneGlycol Dimethyl ether (DGM) and 2-Methoxyethanol (2ME) and the oxygenated compounds were selected based on the availability, price and oxygen content. These oxygenated compounds are blended with diesel fuel in proportion of 6% by volume. Combustion parameters such as in-cylinder pressure and Heat release rate were studied. The engine emission characteristics of the Compression ignition (CI) engine fuelling with oxygenated blends are studied experimentally. The performance of oxygenates on thermal efficiency and specific fuel consumption were studied. Comparing the combustion, performance and emission, the addition of 2-methoxy ethanol blend shows better performance than other two oxygenated blends with diesel and diesel fuel.

Abstract Researchers have investigated reactivity-controlled compression ignition (RCCI) combustion in the past several years because of its excellent combustion, performance, and emission features. In this experimental study, the RCCI combustion strategy was investigated using mineral diesel/ butanol fuel-pair at various premixed ratios (rp) on an energy basis (rp= 0.25, 0.50, and 0.75) at varying engine loads (BMEP of 1, 2, 3, and 4 bar) vis-à-vis baseline compression ignition (CI) combustion (rp= 0.0) strategy. Experiments were performed at constant engine speed (1500 rpm) in a single-cylinder research engine equipped with state-of-the-art features. The outcome of the investigation showed that port injection of Butanol as low reactivity fuel (LRF) improved the combustion and yielded superior engine performance than baseline CI combustion strategy. Engine exhaust emissions exhibited significantly lower nitrogen (NOx) oxides with butanol RCCI combustion strategy than baseline CI combustion strategy. Increasing rp of Butanol showed improved combustion and emission characteristics; however, performance characteristics were not affected significantly. Particulate characteristics of the RCCI combustion strategy also showed a significant reduction in particle number concentration than baseline CI combustion. Slightly different combustion, performance, and emission characteristics of mineral diesel/ butanol fueled RCCI combustion strategy compared to other test fuels such as mineral diesel/ methanol, and mineral diesel/ ethanol-fueled RCCI combustion strategy was an interesting observation of this study. Overall, this study indicated that Butanol could be used as LRF in RCCI combustion strategy engines to achieve superior combustion and emission characteristics.
