を特徴とする内燃機関の燃料供給装置。In a fuel supply system for an internal combustion engine, the fuel injection valve includes a fuel injection valve held and fixed to a mounting part upstream of an intake throttle valve, and has a fuel passage communicating with a fuel pump between the fuel injection valve and the mounting part. A venturi forming a part of the intake passage is formed by the circumferential wall and the outer circumferential wall of the mounting portion, and a backup fuel passage station that communicates the throat of the venturi with the fuel passage detects fuel supply stoppage due to failure of the fuel injection valve. An internal combustion engine characterized in that it is provided with a fuel injection valve abnormality detection means for emitting an abnormality detection signal, and a normally closed valve device that is interposed in the backup fuel passage and opens the valve when the abnormality detection ratio signal is received. Engine fuel supply system.
