s2, when the supply of the lubricating oil is finished, the oil pump stops supplying the lubricating oil, controls the meshing gear of the starter to be meshed with the flywheel gear ring of the internal combustion engine, and controls the starter to drive the meshing gear to rotate so as to drive the flywheel gear ring of the internal combustion engine to rotate and realize the starting of the internal combustion engine;
and S3, in the running process of the internal combustion engine, the oil pump is driven by the starter to work according to working conditions, and stable lubricating oil is provided for the lubricating channel of the internal combustion engine.
9. The method of claim 8, wherein in step S3, the operation of the oil pump is controlled by detecting whether the pressure of the oil in the oil passage of the internal combustion engine is sufficient;
when the engine oil pressure is lower than 150kPa, the engine oil pump is automatically started to work;
when the engine oil pressure is higher than 200kPa, the engine oil pump automatically stops working.
10. The method of claim 8, wherein in step S3, the operation of the oil pump is controlled by the magnitude of the work load of the internal combustion engine;
when the load of the internal combustion engine is 50% of the standard load, the oil pump operates to maintain the lubricating oil pressure of the lubricating oil passage at 300kPa + -30 kPa;
when the load of the internal combustion engine is 100% of the standard load, the oil pump works to maintain the lubricating oil pressure of the lubricating oil channel at 600kPa +/-30 kPa;
when the load of the internal combustion engine is other than the standard load, the oil pump operates to maintain the oil pressure in the oil passage at 330kPa to 570 kPa.
