ABSTRACT:
Disclosed herein is a fuel supply control system for an internal combustion engine. The system comprises a fuel supply member for supplying fuel to each cylinder of the engine; a pressure sensor which outputs a signal representative of an internal pressure of each cylinder under compression stroke; a crankangle sensor which outputs two types of signals, one being a signal which is issued each time a crankshaft of the engine rotates by a given angle, and the other being a signal which is issued each time the crankshaft comes to a given angular position; a pre-ignition judging device for judging whether a pre-ignition occurs or not in each cylinder based on the signals from the pressure sensor and the crankangle sensor; and a fuel supply stop device for stopping the fuel supply to a cylinder when the pre-ignition judging device judges that the cylinder encounters the pre-ignition.
