| Abstract: | This paper introduces a fault of oil mist detector for certain main engine.This fault is resulted from turnoff of a capacitor in the printed circuit board.At that time,according to input-output relation of operational amplifier,a dry battery was used to produce a fixed voltage to simulate the input signal and then make the oil mist detector work normally. |

| Keywords: | oil mist detector capacitor operational amplifier dry battery |
