| 摘 要： | 在CA498Z柴油机上进行了可变喷嘴增压器(VNT)的匹配试验研究。试验结果表明，VNT可以在发动机的整个转速范围内和CA498Z柴油机实现良好的匹配。VNT显著提高了发动机外特性的低速转矩，降低了外特性的排气烟度。扩大了该柴油机低油耗区的转速范围，改善了整机的燃油经济性。

An Experimental Study on the Matching of Variable Nozzle Turbocharger with Turbocharged Diesel Engine |

| Abstract: | The experiment on the matching between a variable nozzle turbocharger (VNT) and CA498Z diesel engine is performed. The results show that the engine can achieve a good performance with VNT in the whole speed range. The torque of engine at low speed is raised largely, the smoke of engine is reduced remarkably, and the fuel economy is improved greatly with the speed range of low fuel consumption extended. |
