| 摘 要： | 采用AVL缸内视频系统对增压直喷式柴油机CC490ZQ实际工作在低、中转速下，缸内燃烧过程进行了可视化试验研究，同时测量了其烟度、HC、C0及NOx并进行了分析。结果表明：进气涡流是着火初期火焰分布形态的主要控制因素，随着负荷和增压压力的升高，导致燃烧室中心区的扩散燃烧及其比例增加；湍流混合对直喷式柴油机缸内混合燃烧起主要控制作用。 |
| 关 键 词： | 内燃机 增压直喷式柴油机 燃烧过程 可视化 排放 |

| Abstract: | Application of the AVL Video System to investigate the combustion process in the cylinder of CC490ZQ turbo charged diesel engine in real working conditions of low and medium speeds with different loads is introduced, and the HC, CO, and NO_x emissions are measured and analyzed by the authors at the same time. It is found that the intake swirl is a main controlling factor of the flame distribution in initial stages in cylinder, the portion diffusive combustion has been increased and the ignition delay is shorten with the intake pressure increased, and the combustion has been improved. |
