| 摘 要： | 对一台高速直喷式柴油机采用柴油／甲醇组合燃烧方式及其纯柴油燃烧方式的燃烧特性进行了研究。其结果表明，采用柴油／甲醇组合燃烧的发动机，燃烧始点晚于采用纯柴油时的燃烧起点，但是燃烧速度快，气缸峰值压力比燃烧纯柴油时高；与纯柴油的双峰放热规律不同，组合燃烧的放热率曲线呈单峰形；组合燃烧的最高燃烧温度比燃烧纯柴油时有所降低．进而从燃烧理论上解释了采用组合燃烧可以同时降低碳烟和NOx排放的原因。

| Abstract: | In this study, methanol was pre-mixed in the intake manifold of a diesel engine,and the combustion characteristics and emissions of the compound combustion were investigated. The results show that combustion start point of the compound combustion is later than that of the diesel, but the combustion rate of the former is faster and the maximum pressure of the former is higher than that of the latter. The heat release rate of the compound combustion is single peak curve, which is different from that of the double peak curve of the diesel. Moreover the maximum combustion temperature of the compound combustion is lower than that of the diesel. The findings provide theoretical explanation to why the compound combustion can decrease the PM and NO_x emissions simultaneously. |
