摘　　要：论述了空气流量传感器计量准确性对电子控制汽油喷射发动机性能的影响程度。以叶片(翼板)式、卡门涡旋式、热线式空气流量传感器等几种常用的传感器为例,从其结构组成、工作原理、故障检测(就车检测,动态检测)等方面进行了介绍,并结合具体车型给出了判断故障的参数限值。The influence degree of air flow sensor measure accuracy on the performance of electrically-controlled gas injection engine was discussed in this paper.Based on the conventional air flow sensors such as blade （wing plate）type, Karman vortex type and hot-line type etc,the structure,working principle and fault detection （static detection,dynamic detection）were introduced,and combined with specific vehicle,the parameter limit value for judging fault were presented.
