An Ozygenating Additive for Reducing the Emission of Diesel Engine
Oxygenated diesel fuel blends have a potential to reduce the emission of particulate matter (PM) and to be an alternative to diesel fuel. This paper describes a new kind of oxygenate additive, ethylene glycol monoacetate (EGM), and its effects on the characteristics of performance and emission of a compression ignition engine. The results show that the engine power outputs decrease and the BSFC increase when the diesel engine fueled with blends, but the diesel equivalent BSFC decrease. The results also indicate that all oxygenated fuels tested in this study show a beneficial effect on reducing smoke emissions at the operation conditions compared with diesel fuel. With the EGM15, an average smoke reduction of 49.9％ and a maximal smoke reduction of 71％ are obtained. The blends have little effects on the NOx emissions at most loads. he CO emissions of the EGMdiesel blends decrease obviously at high load. All these results indicate the potential of EGM-diesel blend for clean combustion in diesel engine.
