PROBLEM TO BE SOLVED: To suppress combustion differences between cylinders by uniformizing recirculation amount of exhaust gas in the respective cylinders, in an internal combustion engine. SOLUTION: In the V 8 irregular interval ignition engine, areas of exhaust passages in a forth cylinder #4, fifth cylinder #5, seventh cylinder #7 and eighth cylinder #8 in which an overlap period overlaps an exhaust stroke of the specific cylinder are set larger than those of exhaust passages in a first cylinder #1, second cylinder #2, third cylinder #3 and sixth cylinder #6 in which the overlap period does not overlap the exhaust stroke.
