摘　　要：解释了阿特金森/米勒(Atkinson/Miller)循环的基本原理,结合国内外Atkinson/Miller循环的研究成果,从提高燃油经济性、减少爆震倾向和降低排放等方面,阐述了Atkinson/Miller循环代替Otto循环带来的益处,并分析了其加速性能和动力性的不足。围绕结构设计参数,总结了影响Atkinson/Miller循环发动机的因素。针对Atkinson/Miller循环的实现,说明了其控制策略。分析了Atkinson/Miller循环的应用,并提出了优化措施。The principle of Atkinson/Miller cycle was explained. Combined with the domestic and foreign research results of Atkinson/Miller cycle, in several ways of improving fuel economy, reducing the knock tendency and reducing the emission, the benefits of Atkinson/Miller cycle instead of Otto cycle were ex pounded. The disadvantages of acceleration performance and power performance were analyzed. In view of the realization of Atkinson/Miller cycle, the control strategy was explained. Application of Atkinson/Miller cycle was analyzed, and the optimization measures were given.
