Abstract
In an air intake system for an internal combustion engine having at least one cylinder with an intake pipe extending between the cylinder and an air collecting box for supplying intake air from the collecting box to the cylinder a diaphragm structure is arranged at the end of the intake pipe and includes an oscillation generator for providing acoustic pressure oscillations to the air in the intake pipe adapted to increase the cylinder air charge as a function of engine operating parameters and the intake air pipe is in communication with the air box via a connecting passage which includes a device for suppressing the acoustic pressure oscillations to prevent their transmission to the air in the air box.
