本文提出了根据发动机故障样本建立故障方程的方法。发动机经验故障方程是不同于发动机小偏差方程的另一类故障方程,它为发动机故障诊断提供了一条简便易行的途径,并且使发动机故障诊断范围扩展到气路分析方法难以适应的场合。文中讨论了经验故障方程的建立方法及其在发动机故障诊断中的应用,给出了利用经验故障进行发动机故障诊断的实例。
This paper presents a method to establish fault equations based on engine fault samples. Engine failure equation is another kind of failure equation which is different from the small deviation equation of engine. It provides a simple and easy way for engine fault diagnosis, and expands the range of engine fault diagnosis to the situation where it is difficult to adapt the gas analysis method. In this paper, the establishment of empirical failure equation and its application in engine fault diagnosis are discussed. An example of using engine fault to diagnose engine fault is given.
