Specifically, the control module 4 may control the high-pressure electric pump 3 and the heating module 5 to be turned on or off according to a detection signal output by the current detection module 6, for example, the current of the high-pressure electric pump 3. When the current of the high-pressure electric pump 3 is greater than or equal to a preset threshold value, indicating that the high-pressure electric pump 3 successfully pumps diesel oil to the engine; the control module 4 controls the heating module 5 to be closed according to the detection signal output by the current detection module 6, the diesel oil does not need to be heated, and when the current of the high-pressure electric pump 3 is smaller than a preset threshold value, the fact that the high-pressure electric pump 3 does not successfully pump the diesel oil to the engine is indicated.
