PROBLEM TO BE SOLVED: To provide a fuel supply system of an internal combustion engine in which deposit can be prevented from attaching to keep the engine performance intact. SOLUTION: There is provided the internal combustion engine that is equipped with a cylinder injection injector 11 for performing fuel injection toward an inside of the cylinder and an air intake port injection injector 12 for performing fuel injection toward an inside of an air intake port and has a region for doing the drive using at least only the air intake port injection injector 12. In the internal combustion engine, the cylinder injection injector 11 is arranged on the lower side of an air intake path 67, while the air intake port injection injector 12 is arranged at more upstream side than a PCV path outlet 70 in the air intake path so as to enable the fuel injection by which fuel in a droplet attaches to a wall surface 67b of the air intake path in the vicinity of a point of the air intake port injection injector 12. Further, a recess 67c is formed on the wall surface 67 of the air intake path. COPYRIGHT: (C)2005,JPO&NCIPI
