摘　　要：介绍了阿特金森/米勒(Atkinson/Miller)循环的基本原理,并且结合了国内外阿特金森/米勒循环的研究成果。使用GT-suite建立6缸中速柴油机模型,并且试验验证了仿真模型的准确性。从对柴油机缸内最高爆发压力、功率、有效燃油消耗率、充气效率、气缸最高温度等性能和降低NOx排放等方面,阐述了阿特金森/米勒循环技术的优劣势和优化方法。The paper introduces the basic principles of Atkinson/Miller cycle combining the research results of Atkinson/Miller cycle at home and abroad. A model of 6-cylinder medium-speed diesel engine is built using GT-suite. Also the accuracy of the simulation model is verified through the test. From the aspects of maximum explosion pressure, power, effective fuel consumption rate, charging efficiency, the highest temperature in diesel engine cylinder and reducing NOx emissions,the advantages and disadvantages and optimization method of Atkinson/Miller cycle technology are described.
