ABSTRACT:
An inlet pipe system for a multicylinder internal combustion engine, especially with two rows of cylinders in a V-configuration, has a tubular inlet distributor 2, from which first individual inlet pipes 4 through 9 proceed which extend in an arc around the inlet distributor and which lead to the individual cylinders of the two rows of cylinders. Second, shorter individual inlet pipes 12 likewise proceed from the inlet distributor and discharge into the pertinent individual inlet pipes. The inlet distributor and the first and second individual inlet pipes are formed by a one-piece part 1 which has a longitudinal hole 14 which cuts the second individual inlet pipes 12 for the cylinders of the two rows of cylinders. Into longitudinal hole 14 a drum controller 15 is inserted which for each second individual inlet pipe 12 has an opening 16 which can be brought into alignment or out of alignment with the pertinent second individual inlet pipe by turning the drum controller 15.
