Abstract
An internal combustion engine has a cylinder, a cylinder head mounted to the cylinder, a piston disposed in the cylinder, and a fuel injection valve. A combustion chamber is defined by the piston, the cylinder head and the cylinder. The fuel injection valve has a plurality of injection holes that injects fuel directly inside the cylinder from a side of the combustion chamber. The injection holes inject fuel in a spray shape with an overall shape, which is formed by a plurality of sprays being injected from the injection holes. The overall shape expands toward the cylinder head and forms one part of a conical shape that is dented near the piston. Central axes of some of the injection holes are oriented toward a boundary portion near the exhaust valve formed at a crown surface of the piston and an inner wall of the cylinder when fuel is injected.
