Performance and Emission Analysis of Diesel Engine Using Oxygenated compounds

Abstract

The addition of oxygenated compounds to diesel, supply additional oxygen which results in more burning of the fuel and thereby reducing emissions. In the present study, two oxygenated compounds, such as Ethoxy ethanol and Ethylene glycol are considered on a 3.7KW, water cooled, and kirloskar engine. The selected oxygenated compounds are blended with diesel fuel in proportions of 5% and 10% by volume and the experimental study is conducted to evaluate the performance and emissions of the diesel engine. The data obtained is compared with the conventional diesel fuel and the results reveal that Brake Thermal Efficiency (BTE) decreased with increase in the blend percentage. CO 2 , HC emissions decreased while NO X emissions increased.

Experimental and Kinetic Studies of Ethylene Glycol Autoignition at High Temperatures

“…The chemical formula is OH–CH 2 –CH 2 –OH and has a high content of oxygen (51.6 wt %). It is observed that EG has similar oxidation reactivity and ignition characteristics as ethanol, indicating that EG has the potential for use as a supplement for ethanol. , The emissions of nitrogen oxides and soot can be reduced when EG in blended in diesel. − Moreover, EG is often selected as a single-component surrogate for the pyrolysis oil, which is a bio-oil used as a substitute for fossil fuels in turbines and internal combustion engines, because that EG has similar chemical and physical properties to those of pyrolysis oil. − In order to model the pyrolysis and combustion processes of EG in practical systems, it is necessary to investigate the reaction kinetics of EG and construct the combustion kinetic mechanism that has been assessed against fundamental experimental data. On the basis of the literature survey, only a few studies have been focused on the kinetic of EG combustion.…”
