<p>The invention relates to a combustion engine comprising a number of cylinder spaces. Two inlet ports (3, 4) to be opened and closed by means of inlet valves and one exhaust port (5) to be opened and closed by means of an exhaust valve are provided for each cylinder space. One inlet channel (11, 12) connects to each inlet port (3, 4) of a cylinder. The inlet channels (11, 12) are in communication with a separate air inlet chamber (14). The air inlet chamber (14) is in communication with an air supply chamber (19) via two air supply channels (17, 18) having different lengths. Means are provided for supplying the air from the air supply chamber (19) to the air inlet chamber (14) either via the longer (18) or via the shorter (17) of the two air supply channels (17, 18), as desired, during operation. Furthermore, means are provided by which the passage of one of the inlet channels can be opened or closed, as desired.</p> |
