Abstract
An 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) communicates with a suction valve (4, 5) respectively. At least two of the suction valves (4, 5) have different closing times in order to increase the air quantity sucked into the cylinder (3), and thereby increase the torque and power of the internal combustion engine (1). According to one embodiment, a throttle can be arranged in each suction channel (6, 7) and the shorter suction channel (6) can be provided with a smaller area of cross section than the longer suction channel (7).
