配气相位对天然气发动机燃烧和排放的影响（Investigation of Effect of Cam Phase on Combustion and Exhaust Characteristics of CNG Engine）
天然气发动机 配气相位 燃烧 排放
2009/9/2
对改装为火花点火式天然气发动机的柴油机配气机构的配气相位进行了优化设计，并在发动机台架上进行了对比试验，研究了配气相位对发动机燃烧及排放的影响。试验结果表明：随着气门重叠角的减小，HC和NOx排放量有所降低，但高转速时过小的气门重叠角，不利于HC排放量的降低；气门重叠角的减小使得缸内可燃气体浓度降低，在抑制NOx生成的同时，也损失了部分功率，因而在降低有害排放的同时，还要兼顾动力性；随着转速的升高...
