发动机点火提前角自动测试系统

Computer Measuring System of Engine Spark Advance for Torque

点火提前角是分电器产品合格与否的一项重要指标。介绍了应用霍尔器件、单稳电路及计算机测控技术等测量发动机点火提前角的方法 ,给出了较为详细的电路原理图 ,对系统的工作过程和设计原理图作了具体的说明 ,并论述了克服点火时尖峰干扰的实用方法。

The engine spark advance is an important factor in quality control of automobile distributors. In addition to introducing a method for measuring the engine spark advance by Hall component and the monostable circuit, the authors present the working process of the system and the design theory. Some methods for solving the problem of rush disturbance during the spark are discussed, and the detailed circuit principle graphs are also given.
