摘　　要：在稳流气道试验台上，使用热线风速仪和自行设计制作的气缸内流场测试系统，对二气门和四气门柴油机模型气缸盖下气缸内流场进行了测量。分析了两种柴油机气缸内流场的形成状况和不同的形成原因。On the steady flow test rig, the in- cylinder flow field underneath the bottom surface of 2 - valves and 4 - valves cylinder head models has been measured respectively by using the Hot Wire Anemometer and the in - cylinder air flow measurement system designed by ourselves. The formation pro- cess and different formation causes of the in - cylinder flow field from two diesel models have been analyzed in this paper.
