摘要
通过分析天然气发动机空气和天然气的流动规律,建立混合气流量与混合器喉口面积、入口角度间的数学模型,对数学模型进行优化求解,以发动机台架试验验证了优化模型使天然气发动机的功率损失降到了最低。
This paper analyzed the flowing regulation of air and NG of CNG engines, The mathematical model between the flows of mixture and the throat area, shrinking degree of mixer can be established; the optimal conclusion can be obtained by optimizing the mathematical model.The results obtained from the engine mapping tested and verification showed that the power lose using NG dropped to the lowest status。
