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 engine, cavity shapes of respective cylinders are changed such that a compression ratio in the first cylinder #1, third cylinder #3, second cylinder #2 and sixth cylinder #6 in which an overlap period overlaps an exhaust stroke of the specific cylinder is set larger than that in the forth cylinder #4, fifth cylinder #5, seventh cylinder #7 and eighth cylinder #8 in which the overlap period does not overlap the exhaust stroke.
