柴油机燃用双生物柴油混合燃料的燃烧排放性能
Performance of Diesel Engine Fueled by Dual Biodiesel Blended Fuel
摘要
Abstract
In this paper,ester-based biodiesel(BDO)was used as raw material,and a series of processes such as continuous hydrodeoxygenation-isomerization were carried out to obtain hydrocarbon-based biodiesel(HVO).Three groups of dual-biodiesel blended fuels,D90B5H5(90%diesel+5%BDO+5%HVO),D80B10H10(80%diesel+10%BDO+10%HVO)and D70B15H15(70%diesel+15%BDO+15%HVO)were prepared respectively.Diesel was used as a reference,and combustion tests were carried out on a TBD234V6 diesel engine to explore the effects of the mixed fuels on its combustion process and emission per-formance.The results show that the equivalent fuel consumption of diesel engines using mixed fuels decreases with the increase of the proportion of dual-biodiesel blending.Under rated conditions,the equivalent fuel con-sumption of diesel engines using D90B5H5,D80B10H10 and D70H15B15 is reduced by 1.0%,2.1%and 2.6%respectively compared with that of diesel.Under various load conditions,although the calorific value of the mixed fuel is lower than that of diesel,its inherent oxygen content and high cetane number are more condu-cive to combustion.Under the comprehensive influence of fuel characteristics,compared with diesel,the maxi-mum explosion pressure of D70B15H15 increased by 0.8%,1.3%,1.5%and 1.9%at 25%,5%,75%and 100%load conditions respectively,and the instantaneous heat release peak time was also advanced.Under rated conditions,compared with diesel,the CO,HC and soot emissions of D70B15H15 were reduced by 11.0%,9.3%and 14.2%respectively,and the NOx emissions increased by 7.2%.In summary,the use of dual-biodiesel blen-ded fuel can improve the fuel quality and the combustion and emission performance of diesel engines.关键词
