| 摘 要： | 针对匹配 J6 110 Z柴油机的 H1F增压器混流涡轮进行了涡轮性能试验 ,并将其试验结果与原径流涡轮试验结果进行了分析和比较。试验结果表明 :由于混流涡轮兼有径流和轴流涡轮的流动特性 ,其流通能力较直径相当的径流涡轮大 ,这对于改善车用增压柴油机的加速性能是有益的 ;在低相似转速情况下 ,混流涡轮的最高效率比径流涡轮高 ,并且最高效率点与径流涡轮相比向小 u/ c0 方向移动 ,这对于改善车用增压柴油机的低速性能是有益的。

| Abstract: | Turbine experiment on the mixed flow turbine for H1F turbocharger,which is currently used in J6110Z diesel engine,was undertaken.The experimental results were analyzed and compared with that of currently used radial turbine.It can be seen from the mass flow character comparison that since it has combined flow character of the radial and axial flow turbine,the mixed flow turbine has larger flow capacity than relevant radial turbine,which will benefit the acceleration character for turbocharged diesel engine.The efficiency experimental result also shows that the mixed flow turbine can obtain higher maximum efficiency at lower velocity ratio u/c 0,which will benefit the low speed character for turbocharged diesel engine. |
