The corresponding relation of the overflow pressure threshold, changing along with the temperature of engine oil, of an engine oil system is set, wherein when t is smaller than TO, p is equal to PO, when t is larger than or equal to TO but smaller than TC, p is equal to PO+kdeltat, and when t is larger than or equal to TC, p is equal to PO+kTC; after the diesel engine is started, the diesel engine can be loaded to reach the working condition with the rated rotating speed or the rotating speed smaller than the rated rotating speed, meanwhile, the real-time overflow pressure threshold is obtained according to the corresponding relation, and the engine oil pressure of the engine oil system is regulated. According to the control device for achieving the method, a temperature control valve can be connected with an overflow pressure reducing valve in parallel, and the temperature control valve is initially in a starting state and is gradually closed along with the gradual rising of the engine oil temperature. The structure is simple and compact, and cost is low. The initial pressure of the engine oil system after engine starting is regulated continuously along with the change of the engine oil temperature, parts such as a supercharger and an oil injection pump cannot be damaged, meanwhile, the lubricating and cooling effects are reliably ensured, the time for warming-up is saved, and the light oil saving effect of a heavy oil unit is especially obvious.
