The invention relates to an electromagnetic valve control device for engine piston cooling, and belongs to the technical field of engine piston cooling. The electromagnetic valve control device comprises a controllable one-way valve, an electromagnetic control hydraulic pilot valve, an oil inlet pipe, a cooling oil pipe, a control oil pipe and an installation support. The oil inlet pipe is connected in the controllable one-way valve and the electromagnetic control hydraulic pilot valve. The controllable one-way valve and the electromagnetic control hydraulic pilot valve are fixed to the installation support. By beans of connection of the control oil pipe, the controllable one-way valve is connected with the cooling oil pipe. By means of oil supply of the electromagnetic control hydraulic pilot valve, the controllable one-way valve is controlled to control the one-way valve to be opened and closed in real time according to an engine ECU instruction so that oil spray can be precisely controlled and unnecessary oil spray can be reduced. By means of the electromagnetic valve control device, the social benefits including engine energy conservation and emission reduction and environment protection are achieved, the electromagnetic valve power consumption is low, and reliability is high.
