The invention relates to an intelligent controlled fuel oil supply system of a gasoline engine. The fuel oil system consists of an oil pump, an oil spray guide rail, a pressure reflux valve, an oil tank, a one-way valve, an oil supply pipeline and an oil return pipeline. The fuel oil system is characterized in that: a pressure sensor, an intelligent controller, a bus and an alarm circuit are increased; a certain voltage is output to a motor of the oil pump after calculation and judgment by control software of a microprocessor of the intelligent controller, and meanwhile the microprocessor detects a pressure signal on the pressure sensor and modifies the voltage value transmitted to the motor of the oil pump at any time according to the pressure signal to keep the pressure of the system stable; and the microprocessor detects and judges the problem of the fuel oil supply system and gives an audible and visual alarm signal in time. The system has the advantages of energy conservation, consumption reduction, inte
