Abstract
An intake pipe system for a multicylinder internal combustion engine, in particular one with two cylinder banks arranged to form a V, has a tubular intake distributor 2 from which extends a first set of individual intake pipes 4 to 9 which extend through an arc around the intake distributor and lead to the individual cylinders of the two cylinder banks. A second set of shorter individual intake pipes also extend from the intake distributor and discharge into the associated individual intake pipes. The intake distributor and the first and second sets of individual intake pipes are made up of an integral casting 1 having a longitudinal bore 16 intersecting the second set of individual intake pipes. There is introduced into each longitudinal bore 16 a casing having openings 17 aligned with the second set of individual intake pipes, in which bore a pivoting valve 14 is mounted on a common shaft 20 which is embedded in the casing 15.
