| 摘 要： | 在直喷式增压柴油机上进行了供油提前角对生物柴油发动机动力性、经济性和排放性能影响的研究。试验结果表明:与柴油相比,推迟供油提前角后生物柴油的动力性下降,燃油经济性恶化,NO_x和烟度排放均有不同程度的降低。推迟供油提前角对生物柴油的喷油压力和滞燃期影响不大,但喷油始点和燃烧始点均迟于柴油。与柴油相比,推迟供油提前角后最高气缸压力下降,放热峰值出现时刻提前,指示热效率降低。燃烧始点与NO_x排放的相关性最大,喷油始点和放热峰值出现时刻也与NO_x排放呈弱相关性。 |
| 关 键 词： | 内燃机 生物柴油 供油提前角 燃烧 排放 燃烧始点 |

| Abstract: | The effects of the injection timing on power output,fuel consumption and emission were investigated on a turbocharged DI injection diesel engine fueled with biodiesel and diesel.The results indicate that comparing with the diesel engine,retarding injection timing for the biodiesel engine the NO_x and smoke emissions decrease,the power output and fuel consumption deteriorate,the fuel injection pressure and ignition delay are about the same,the start of injection and combustion are later,the max.cylinder pres... |
| Keywords: | IC engine biodiesel injection timing combustion emission start of combustion |
