The invention discloses an electric metering pump for an aircraft engine. The electric metering pump comprises a power supply interface, a communication interface, a drive control unit, and a lubrication cooling pump, a motor and a main oil pump which are coaxially connected, wherein the drive control unit is connected with the power supply interface and the communication interface and is used for driving the motor to operate and controlling the rotating speed according to a control command; the motor is used for driving the lubrication cooling pump and the main oil pump to rotate; the main oil pump is used for pressurizing oil liquid which flows into the main oil pump; and the drive control unit is used for controlling the oil supply amount of the main oil pump by controlling the rotating speed of the motor. By the electric metering pump, the fuel oil increasing and metering functions of the aircraft engine is realized, the structure of an engine transmission accessory can be eliminated or greatly simplified, and the maximum section area and the weight of the engine can be reduced; in addition, fuel oil does not flow back to an inlet or an oil tank of the pump, so that a hydraulic oil channel is simplified, the energy loss of a system is reduced, the efficiency of the system is improved, and the additional temperature rise of the fuel oil is reduced or eliminated.
