新型多碳醇-柴油燃料在发动机上的应用研究

Application Research of the Carbon Alcohols Diesel Fuel on Engine

本试验在一台S195柴油机上进行,试验结果表明,新型混合燃料的油耗率比纯柴油要高,但随负荷的增大,这种差距呈下降趋势。新型混合燃料在较大工况范围都保持较低的CO排放量。两种新型燃料的HC排放曲线呈相同的规律,绝大部分工况下,新型混合燃料的HC排放要高于纯柴油。新型混合燃料的NOx排放比纯柴油低,并且随燃料中碳原子数的增加,NOx排放进一步降低。新型混合燃料的碳烟排放比纯柴油低,BL20D80燃料对碳烟排放的改善要优于HL20D80燃料。

This test was operated on a S195 diesel engine.The test results show that fuel consumption rate of new hybrid fuels is higher than pure diesel fuels.But by the increasing of load,the gap between them drops.New hybrid fuels in wider range of conditions remain low CO emissions.HC emissions curve of these two new fuels follow the same rule.Furthermore,in most of the conditions,new hybrid fuels＇ HC emissions are higher than pure diesel.NOx emissions of the new hybrid fuels are lower than the pure diesel fuels;with the increasing number of carbon atoms,NOx emissions further decrease.Soot emissions of new hybrid fuels are lower than the pure diesel.And on improvement of soot emissions,BL20D80 is better than HL20D80.
