摘　　要：本文首先基于CFD技术,对某PCV阀的内流场进行仿真分析,计算出三种设计方案在不同发动机工况下的流场分布以及流量特性,通过与发动机实际窜气量进行匹配,找出了最优的设计方案,最后进行试验验证。The paper had a simulation analysis on internal flow - field of a certain PCV valve based on CFD technology. Flow - field distribution and flow characteristic of three design projects were calculated at different operation points. The optimum design project was found out after the flow characteristic ＇and actual blow -by gas were matched. Finally , it was verified by experiments.
