乙醇/柴油燃料配制和对柴油机性能影响的模拟
Blend Fuels of Ethanol and Diesel Concoction and Its Influence on Diesel Engine Performance
摘要
Abstract
First, butanol, heptanol, biodiesel and sorbitan monooleate were chosen as the solubilizers. The solubilization capacity of these solubilizers were researched. Then the experiments on the ethanol-diesel blend fuels in different ethanol volume percentages (10%, 20% and 30%) at different temperatures (from 5 ℃ to 60 ℃) were conducted. The experiential formulas about density, surface tension and viscosity varied with ethanol volume percentage and temperature were generalized. Finally, the simulation research for the effect of ethanol volume percentages on the diesel engine performance was conducted. With the increasing of ethanol volume percentage, the fuel atomizing process improved, wallfilm mass decreased, NOX and soot emissions decreased, engine power performance penalized, while equivalent indicated specific fuel consumption and combustion noise reduced. The comprehensive performance of the diesel engine is the best when ethanol volume percentage is 10%.关键词
