| description | The invention discloses a pressure-limiting valve fault detection method and device, electronic equipment and a storage medium, and belongs to the technical field of engines, and the method comprises the steps: collecting a data set related to an engine in real time in the operation process of the engine, and when a detection period is reached, determining the fault of the pressure-limiting valve; screening each target data set in a preset engine oil temperature interval from each data set acquired between the current detection period and the previous detection period, and constructing a scatter diagram of the engine speed and the engine oil pressure based on the engine speed value and the engine oil pressure value in each target data set, based on each target data set and a preset opening pressure value of the pressure-limiting valve, determining a first set and a second set in each target data set, performing straight line fitting on the first set and the second set in the scatter diagram, and determining a |
