- the noise attenuation device is disposed in the circuit zone air intake extending between the turbocharger 2 and a cooler 3 suitable for cooling the air coming from the turbocharger 2.
- This privileged arrangement brings together in a single element noises and rigid air circulation pipe which, until now, were realized in the form of two differentiated elements.
- This noise attenuation device is in the form of a section 1 of integrated pipe by each of its ends to the air intake circuit.
- One end of the pipe section 1 is a 2A air inlet while the other end constitutes a 2B outlet of air.
- section 1 of conduct presents at each of its extremities a section of reduced size to constitute a connecting end solidarisable to the rest of the air intake system, preferably by welding waterproof.
- connection ends formed in one piece with the section 1 of conduct, extend to each end of section 1 of driving beyond the shoulder formed by the narrowing of the section.
- This section 1 of pipe is formed by the assembly of two half-shells represented in 3 and 4 in the figures.
- This section 1 of driving is partitioned longitudinally to delimit, along an axial air passage connecting the air intake 2A and the outlet 2B of the driving section 1, at least one blind volume consisting of a resonance chamber 6.
- This axial air passage is called the main section of conduit.
- This axial passage can thus communicate, via at least one opening 7, with the volume one-eyed constituent of the resonance chamber 6 to establish a air communication between resonance chamber 6 and main section 5 of conduit.
- each half-shell 3, 4 section 1 is partitioned using at least one partition 8, 9 longitudinal. This partition, represented in 8 for the half-shell 3 and in 9 for the half-shell 4, came from molding with the half-shell.
- the bottom of the half-shell is constituted, seen in cross section, of a concave portion corresponding to the area used to delineate the portion of the main section 5 of ducts adjoined on each side by two bulges constituting the part of bottom of the chamber 6 delimited by means of said half-shell.
- the realization of the bottom wall of each half-shell in the form of a lobed wall allows to increase the volume resonance chambers.
- the resonance volume delimited by the partitions 8, 9 longitudinals opposite the half-shells 3, 4 is compartmentalized by through transverse walls 10, 11 transverse molded with each half-shell 3, 4.
- These transverse walls, represented in 10 for the half-shell 3 and 11 for the half-shell 4, extend with their free edge 15, at least as far as the joint plane of the half-shells.
- These walls transversal thus come by their free edge in bearing contact in the state assembled half-shells 3, 4 so as to delimit along the section 5 main driving a plurality of chambers 6 aligned resonator type of Helmholtz allowing broadband attenuation of noises.
- each half-shell 3, or respectively 4 has two parallel longitudinal walls 8 or 9, respectively disposed on either side of the main driving section 5 so as to present two series of chambers 6 resonance characteristics identical or different acoustics. These 6 resonance chambers can thus present a growing volume from the air inlet 2A towards the 2B air outlet of said section 1 of pipe.
- the spacing between the walls transverse 10 or respectively 11, on the one hand, the shape and the dimensions notches 14 of the longitudinal wall 8 or respectively 9 of the other part are chosen according to the frequency range of the noise to be attenuated.
- the walls 10 and 11 of transverse partitioning of half-shells 3, 4 are respectively connected to the wall 8, 9 longitudinal, of said half-shell 3, 4, in the zone of said longitudinal wall 8, 9 extending between two notches 14, so as to form as many chambers 6 than notches 14.
- the attenuation device noises include, on both sides of the main driving section, each time a series of five rooms, ie a total of ten rooms of resonance.
- Each room in a series of rooms is sized differently, the chambers being identical from one series to another of the fact that the half-shells are, for reasons of simplification of the manufacture, made identical. Both sets of rooms are realized symmetrical with respect to the median longitudinal plane of the driving section.
- each half-shell presents along its longitudinal edges a rim whose outer face is intended to come into bearing contact with the face external edge of the corresponding half-shell to form a plan seal 13 half-shells in the assembled state.
- the edges 12, 15 free in bearing contact with longitudinal walls 8, 9 and transverse 10, 11 are assembled to one another in a sealed manner, preferably welded.
- the delimited chambers 6 do not communicate with each other. It could also have been planned similar to making notches in the transverse walls 10, 11 of in order to ensure communication between the resonance chambers 6.
- the section reduction to each of the ends of the section 1 of pipe to delimit end pieces connection to the rest of the air intake circuit makes it possible to delimit a shoulder zone.
- the longitudinal walls 8, 9 of partitioning extend into the enlarged section of Section 1 of the driving to the right of said shoulder.
