To provide an internal combustion engine capable of suppressing adhesion of fuel onto an inner surface of cylinder or onto a piston.
In the internal combustion engine 1 with a fuel injection valve 13 mounted on an engine body 3 so that a tip end 13a faces into a cylinder 2, from which fuel is injected so that it is spread from the tip end 13a, at least one of a direction in which fuel is injected from the tip end 13a, a spread angle θ of fuel injected from the tip end 13a, and a spray length of fuel spray to be injected from the tip end 13a is set such that fuel injected from the tip end 13a passes through a contact position CP at which it first contacts an inner surface of the cylinder 2 and a contact distance L which is a shortest distance between a plane P1 perpendicular to a center axis CA of fuel injected from the tip end 13a and the tip end 13a becomes 60 mm or greater.
