| 摘 要： | 本文介绍了一种汽油机空燃比的微机开环控制系统。研制了用电磁阀控制的化油器旁通空气装置作为执行机构。采用了转速和节流阀开度传感器来检测汽油机工况并论述了建立空燃比控制模型的一种新方法。试验表明,采用这一控制系统后,燃油经济性在大部分工况区均有较大改善。

| Abstract: | In this paper the air-fue lratio micro-processor controlled system is presented. The carburetor by-pass air inlet controlled by an on-off solenoid valve is used as an actuator. A speed sensor and a throttle position sensor are applied to the detection of engine operating conditions. A new method for establishing the economical A/F control model is also cited. Experiments show that the fuel economy is improved in most operating region while this control system has been used. |
