(6)空气流量传感器,其结构如图9所示。在矩形管道中装有矩形测量片2,此片在流动空气的压力和复位弹簧6的作用下,可转到一定的角度,其转角由同轴连接的电位器8转变成电压信号,输入到控制器内。为了减少进气管内压力波动对测量片的影响,还附加了阻尼片5,以防止测量片的振动。空气流量传感器是燃油喷射系统的关键部件。 (7)节气门开度传感器,其结构如图10所示。它是一个带有滑动刷形接触电位器形式的开关,其滑动刷形片直接装在节流阀的轴上,节流阀不同的开度决定不同的电位值。当
(6) air flow sensor, the structure shown in Figure 9. In the rectangular pipe is equipped with a rectangular measuring piece 2, the film in the flow of air pressure and reset the role of the spring 6, can be turned to a certain angle, the rotation angle by the coaxially connected potentiometer 8 into a voltage signal input Controller inside. In order to reduce the influence of the pressure fluctuation in the intake pipe on the measuring piece, an additional damping piece 5 is added to prevent the measuring piece from vibrating. The air flow sensor is a key component of the fuel injection system. (7) Throttle opening sensor, the structure shown in Figure 10. It is a switch with a sliding brush-shaped contact potentiometer in the form of a sliding brush mounted directly on the axis of the throttle valve, throttle opening of different determines the different potential values. when
