Internal combustion engine with fuel injection valve

An internal combustion engine includes a fuel injection valve (6) which is inserted into an insertion hole (8) in a cylinder head (2) in which intake ports (41,42) having intake valve openings (41a,42a), respectively, and an exhaust port (5) having exhaust valve openings (51a,52a) are provided so as to be fixed therein by a clamp (70). Four valve openings comprising the intake valve openings (41a,42a) and the exhaust valve openings (51a,52a) of each cylinder are disposed around the fuel injection valve (6) at intervals in a circumferential direction, and the clamp (70) is disposed, as viewed from the top, between the intake valve opening (41a) and the exhaust valve opening (51a) which constitute only two adjacent valve openings that form a widest interval of intervals that are formed between any two valve openings (41a,42a;42a,52a;51a,52a;41a,51a) which are adjacent in the circumferential direction.
