摘要

为了研究加氢生物柴油-乙醇-柴油三元燃料的燃烧和排放性能

配制加氢生物柴油-柴油二元燃料(PHC10、PHC20、PHC30)和加氢生物柴油-乙醇-柴油三元燃料(PHC5E5、PHC10E10、PHC15E15)

选取1 800 r/min时25%、50%、75%和100%负荷工况作为测试工况

在高压共轨四缸柴油机上对各混合燃料进行燃烧试验研究。试验结果表明:在100%负荷工况下

与柴油相比

二元燃料、三元燃料的着火时刻分别提前、滞后

这是加氢生物柴油和乙醇的不同十六烷值影响的结果; 二元燃料的着火时刻提前

着火延迟期内形成的可燃混合气数量较少

而且加氢生物柴油的低热值较低、运动黏度较高

在主燃烧阶段内的最大缸压和放热率峰值均低于柴油; 对于三元燃料

初期燃烧放热可以有效降低乙醇的汽化潜热带来的不利影响

而且乙醇挥发性能较好和氧含量较高

使得三元燃料在主燃烧阶段内的最大缸压和放热率峰值均大于柴油。三元燃料的HC和CO排放均高于二元燃料

二者的差异随着负荷的增大而减小; 混合燃料的NO

排放受负荷影响较大

在25%和50%负荷工况下

三元燃料的NO

排放低于二元燃料

而在75%和100%负荷工况下呈现相反的趋势; 三元燃料的碳烟排放低于二元燃料。该研究可为加氢生物柴油-乙醇-柴油三元燃料在发动机上的应用提供基础数据。

Abstract

Hydrogenated biodiesel-diesel binary blends(PHC10

PHC20

PHC30)and hydrogen-ated biodiesel-ethanol-diesel ternary blends(PHC5E5

PHC10E10

PHC15E15)were prepared to conduct the combustion and emissions research on a common rail diesel engine under the conditions of 25%

50%

75% and 100% loads at 1 800 r/min. It was revealed that the ignition timings of the binary blends and ternary blends were advanced and lagged respectively under 100% load

due to different cetane numbers of hydrogenated biodiesel and ethanol. Owing to the less combustible mixture in the ignition delay affected by the advance of ignition timing of binary blends

the smaller lower-heating value

and the higher kinematic viscosity of hydrogenated biodiesel

the maximum cylinder pressure and heat release rate of the binary blends in the main combustion term were lower than those of diesel. The heat released from the initial combustion term could overcome the disadvantage of latent heat of vapori-ation of ethanol. Mean
