In an arrangement of intake conduits for a multi-cylinder combustion engine with three inlet valves 4, 5, 6 per cylinder, leading to which are individual intake conduits 9, 10, 11 of different lengths, of which the shorter individual intake conduits 10, 11 can be connected by opening of shut-off valves 18, 19 as the speed and/or load increases, when a shorter individual intake conduit is connected the effective length of each individual intake conduit is shortened to its length by corresponding inflow apertures 22, 24, 26 being provided which are regulated by control flaps 23, 25, 27. This ensures that the ram pipe lengths of all individual intake conduits switched on is the same, thereby guaranteeing an optimum power output. …<IMAGE>… |
