| 摘 要： | 在共轨柴油机上进行了燃用BD5生物柴油的1?000?h可靠性试验，考察长时间燃用生物柴油对柴油机零部件的磨损情况，可靠性试验后对主要零部件进行拆检，主要摩擦副轴颈处可以观察到加工痕迹或光亮，气门处有少量的积碳；测量了主要运动件的磨损量，分析了活塞组、连杆组、曲轴组及配气机构的磨损情况；验证了共轨柴油机长时间燃用生物柴油的可行性。研究结果表明：1?000?h试验后，4缸油环的磨损量为0.004?mm；3缸连杆小头的磨损量为0.043?mm；2缸主轴颈的磨损量为0.003?mm；1缸和2缸的进气门下沉量最大，约为0.009?mm；试验过程中，柴油机各零部件均未发生断裂、剥落、烧蚀、黏结等异常现象。燃烧BD5生物柴油对柴油机主要零部件无异常影响，柴油机可长时间燃用生物柴油。 |

| Abstract: | The 1 000 h reliability experiment was carried out on the common rail diesel engine using BD5 biodiesel. The wears of engine parts were investigated after experiment. By dismantling and examining the engine parts, processing traces or visible light of major friction journal could be observed, and there was a small amount of coke at the valve. The wears of the main moving parts were measured after the reliability experiment. The wears of piston, connecting rod, crank group and valve train were analyzed. The results showed that, the diesel engine could burn biodiesel for long time without problem, after 1 000 h test, the wear of oil ring for cylinder 4 was 0.004 mm, the wear of small rod for cylinder 3 was 0.043?mm, the wear of crankshaft for cylinder 2 was 0.003 mm. The maximum subsidence of valve for cylinder 1 and cylinder 2 was 0.009 mm. During the experiment, the parts of diesel engine were not broken, peeled off, ablation or bonded. Burning biodiesel had no exceptionally influence to the diesel major parts. |
