The invention relates to a novel electric control fuel oil system. The novel electric control fuel oil system comprises a fuel tank body, a carbon tank, an oil filling pipe, an oil pump, an electric control exhaust valve, air vents, an air pressure sensor, a liquid level sensor, an air vent pipe, an oil supply/return pipeline, a control unit and an electric control check valve. The air vents of the carbon tank and a fuel tank are in communication with the electric control exhaust valve through the air vent pipe, the electric control exhaust valve is arranged in the fuel tank body, and a pressure type liquid level sensor is arranged at the bottom of the fuel tank body. The air pressure sensor is arranged at the top of the fuel tank body, the electric control check valve is arranged at the joint of the oil filling pipe and the fuel tank body, and the control unit communicates with the whole vehicle ECU in the form of a CAN bus. According to the technical scheme, the design is ingenious,and the structure is compact. The rapidity and high sensitivity of an electric control valve are utilized to quickly exhaust gas to control the internal pressure, the smoothness of oil filling is improved, and the phenomena of back injection and back surge are eliminated.
