The first chamber 101 and the second chamber 102 both store engine oil, and in a severe cold environment, the heating component 30 only needs to heat the engine oil in the second chamber 102, and the engine oil circulating in each component of the engine is also the heated part of the engine oil extracted from the second chamber 102; meanwhile, when the temperature of the second chamber 102 reaches a preset value, the valve 40 is opened, the engine oil in the first chamber 101 and the engine oil in the second chamber 102 are in contact with each other, the engine oil in the first chamber 101 can be heated, the amount of the engine oil to be heated is reduced on the premise that the volume of the oil pan body 10 and the storage amount of the engine oil are not reduced, and the heating time is shortened.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
