The invention discloses an efficient lubricating oil pumping energy-saving electromagnetic device and belongs to lubricating equipment of internal combustion engines. An electromagnetic coil of the efficient lubricating oil pumping energy-saving electromagnetic device is located outside an oil pump shell. A protection shell is fixed to the oil pump shell. A buoyancy force cavity is fixed under the protection shell. A filter is fixed to an oil inlet of the lower end of the oil pump shell. An oil outlet valve is fixed in a central hole of the oil pump shell. A pushing spring and a magnetic inducing piston are arranged in the oil pump shell. The pushing spring is pressed on the lower end face of the magnetic inducing piston in an abutting mode. A sealing ball or a sealing cone seals a lubricating oil inlet channel of an oil inlet cavity. A sealing cap seals a lubricating oil inlet channel of an extrusion cavity. A fixing plug is fixed in a plug hole in the magnetic inducing piston. A sealing ball or a sealing cone is installed in an inner conical hole. The efficient lubricating oil pumping energy-saving electromagnetic device is compact in structure, small in vibration, high in electric energy utilization rate, strong in power, capable of pumping lubricating oil to the surface needing to be lubricated when an internal combustion engine is not started and suitable for installation and application of the internal combustion engine, and the lubricating oil pressure is not decreased when the rotation speed of the internal combustion engine is decreased.
