摘　　要：根据四冲程涡轮增压柴油机的通流特点， 假定气流为一元准稳定流动气流， 提出了一种用于分析扫气压比ｐｓ／ｐＴ 与增压柴油机增压系统及运行参数关系的简化的数学模型． 利用该模型可预测和改善涡轮增压柴油机的匹配性能．On the basis of the flow characteristics of turbocharged four_stoke diesel engines and assuming that gas flow is one_dimensional quasi_steady flow, a simplified mathematical model is presented which is used for analyzing the relationship between the scavenging pressure ratio p s/ p T and parameters of the turbocharging system and running conditions for the engine in question. This model can be used to predict and improve the matching performances of turbocharged diesel engines.
