Abstract
A fuel supply control system for an internal combustion engine, having fuel injection valves for supplying the engine with fuel having its pressure regulated to a predetermined value. A temperature sensor detects a temperature value representative of the temperature of fuel being supplied to the fuel injection valves. When the temperature value detected by the sensor is higher than a predetermined value at the start of the engine, an electronic control unit causes a solenoid-operated selector valve to operate to increase the pressure of fuel being supplied to the engine over a period of time dependent on the temperature value detected by the sensor from the time the engine is started.
