Abstract:
Internal combustion engine (1) which comprises at least one cylinder (3), at least two suction valves (4, 5) per cylinder (3), and individual suction channels (6, 7) of longer and shorter length for each cylinder (3), each suction channel (6, 7) communicating with a suction valve (4, 5) respectively, and at least two of the suction valves (4, 5) have different closing times, characterized in that one suction valve (4) which communicates with a shorter suction channel (6) closes earlier than another suction valve (5) which communicates with a longer suction channel (7), so that suction air which reaches the cylinder space (11) is prevented to flow out through the first suction channel (6) when a high-pressure wave (7) reaches the cylinder space (11).
