| 摘 要： | 在柴油机的故障诊断中，常采用多个传感器测取柴油机的多个信号，如：振动信号，油压信号等进行分析判断各缸工作状况，所需设备复杂，数据处理繁杂。而本文提出了只用一个声压传感器就可定位并分析各缸的工况，较之以往的方法简单易行。

| Abstract: | In the diagnosis of diesel fault, many sensors are conventionally used to get several kinds of signals such as vibration signals and oil pressure signals, in order to diagnosis the diesel state accurately. This paper puts forward a new method that can diagnosis the diesel state by using only one sensor, one that measures the near-field acoustic pressure. Compared with prior methods, this method is simple and easily realizable. |
