Abstract
An internal combustion engine fuel injection system includes a temperature sensor for detecting the temperature of the fuel or cooling water in the engine. When the detected temperature is higher than a given value, e.g., 50.degree. C., a pressure regulator for controlling the pressure of fuel supplied to a fuel injection valve is controlled so as to increase the fuel pressure irrespective of the intake pipe negative pressure and thereby increase the quantity of fuel supplied to the engine. In the case of an electronically controlled fuel injection control system, a predetermined correction quantity corresponding to the detected temperature from the temperature sensor is added to the basic fuel injection quantity calculated in accordance with given operating parameters of the engine, thereby increasing the quantity of fuel supplied to the engine.
