摘　　要：从喷雾高速摄影试验和多维数值模拟等方面探讨了双卷流燃烧系统促进柴油机喷雾与空气快速、均匀混合的工作机理。同时,在150系列柴油机上的试验结果表明,双卷流燃烧系统可以有效降低油耗,并且适用于高增压下的柴油机工作过程;在此基础上采用可调进气涡流,可以使发动机经济运行区域进一步扩大。The quick mixing principle of double swirl combustion system (DSCS) is discussed in this paper according to High Speed Photography tests and multidimension simulations of diesel fuel spray.Meanwhile,the tests on several diesel engines of 150 serise showed that DSCS can reduce fuel consumption effectively and be applied on the diesel engine under high turbocharging pressure.The test results also showed that DSCS can enlarge the economical operation zone of diesel engine with variable intake swirl system.
