汽油机控制参数的电控与测试研究

Research on Measurement and Control of the Parameters for Electronic Control Gasoline Engines

以MCS 80 98单片机作为中央控制器 ,设计了一种电控发动机基本控制参数测试装置 ,利用该装置对汽油机的空燃比和点火提前角等控制参数进行了实际测试。应用测试获得的数据对发动机进行实际控制时 ,取得了比较满意的效果。

Measurement and control of the parameters, such as air-fuel ratio and spark timing, is one of the key factors to accomplish the matching of electronic control system to gasoline engines. In this paper, an apparatus for measuring the maps used by multi-point gasoline injection system has been developed by using the MCS-8098 single chip microprocessor as a controller. The map characteristics of air-fuel ratio and spark advance angle of an automotive engine were measured and good results were got from the engine controlled by the measured data in this paper.
