A Simulated Study on the Performance of Diesel Engine with Ethanol-Diesel Blend Fuel

Abstract

This paper describes the simulated study on atomization, wall-film formation, ombustion and emission forming process of ethanol-diesel blend fuels in a high peed light duty diesel engine. The result shows that increased ethanol volume ercentage of the blend fuels could improve atomization and reduce wall-film ormation. However, in the meanwhile, with the increased ethanol volume percentage, ow heat values of blend fuels decrease, while both total heat releases and cylinder ressures drop. By adding codes into the FIRE software, the NOx and soot formation egion mass fractions are outputted. The simulated results display a good correlation ith the NOx and soot formation. Besides, the NOx, soot and CO emissions decrease ith the increased ethanol volume percentage. The power output of engine penalize, hile energy utilization of blend fuels improve and combustion noise reduce, owing to he increased ethanol volume percentage.
