| 摘 要： | 对燃用不同掺烧比例生物柴油的一台进口车用增压中冷直喷柴油机进行动力性、经济性和排放特性试验.结果表明:发动机功率基本上随生物柴油掺烧比例增加呈线性下降趋势;油耗随掺烧比例增加而增加;生物柴油有一定的降低CO排放的效果,但不是很明显;掺烧生物柴油对HC和颗粒物的排放有明显的降低效果;但对于Nox,情况有些不同:掺烧10%的生物柴油几乎在所有工况下Nox排放都有所降低,而掺烧20%和30%生物柴油后,Nox排放则略有增加,且基本在3 000r/min以上的工作区域.

| Abstract: | The tests on power,fuel economy and emission characteristics of a turbo-charged direct injection diesel engine fueled with different blending ratio of bio-diesel are conducted.The results show that with the increase in bio-diesel blending ratio,engine power basically drops linearly,fuel consumption increases,CO emission reduces in certain degree and HC and particulate emissions decreases markedly;For NOx emission,it reduces under almost all conditions when bio-diesel blending ratio is around 10%,but when th... |
