The present application provides an engine oil pump control method, device, and engine, the method comprising: obtaining an oil discharge command indicating that the engine oil discharge switch is in an open state; controlling the one-way three-way valve in the engine to switch to the oil discharge position , the first end of the one-way three-way valve is connected with the oil inlet pipeline of the engine lubrication system, the second end of the one-way three-way valve is connected with the output pipeline of the electronically controlled oil pump of the engine, and the one-way The third end of the three-way valve communicates with the outside as the oil discharge port of the engine; the electronically controlled oil pump of the engine is controlled to start, so that the oil in the engine is discharged through the oil discharge port of the one-way three-way valve. During the oil discharge process, the user only needs to trigger the oil discharge switch to complete the discharge of the diesel engine oil, and the user does not need to participate in the follow-up, the process is simple, and the labor force is released.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to an engine oil pump control method, device and engine. Background technique [0002] When the vehicle runs for a certain mileage, the engine needs to be maintained. At this time, the residual oil in the engine needs to be drained. In the prior art, in the process of engine maintenance, the engine is usually drained by hand pump mechanically. Oil work, the whole process requires the user to participate in the whole process, a waste of human resources. Contents of the invention [0003] In view of this, the embodiments of the present invention provide an engine oil pump control method, device, and engine to solve the problem of wasting human resources during the engine oil discharge process in the prior art. [0004] In order to achieve the above purpose, embodiments of the present invention provide the following technical solutions: [0005] A method for controlling an engine o...
