| 摘 要： | 可变喷嘴涡轮调节技术是改善增压柴油机低速性能、降低柴油机排放的有效措施。将所设计的转叶式可变喷嘴涡轮增压器进行了涡轮性能试验,试验结果表明它能够有效地调节涡轮特性。进行了可变喷嘴涡轮增压器与CA6106柴油机的匹配试验,并将其结果与带放气阀增压器的试验结果进行了比较,结果表明CA6106柴油机高速油耗和整个外特性烟度都得到明显的改善。

| Abstract: | Variable geometry turbine(VNT) can improve the low-speed performance and emission of turbocharged diesel engine. Turbine experiment of VNT with rotating vane, which is designed for CA6106 diesel engine, was undertaken. The results show that turbine performance can be adjusted effectively. The matching test for CA6106 diesel engine with VNT was also carried out, and the results were compared with those with waste-gate turbocharger. It can be shown that using VNT, the fuel consumption at high speed and the smoke in external characteristic curve decrease. |
