Air anti-recycling partition for air intake circuit of internal combustion engine of motor vehicle, has orifices connected to air intake line, where orifices communicate with inner volumes that are sized for forming acoustic resonator

摘要

The partition (6) has orifices connected to an air intake line (5), where the orifices respectively communicate with inner volumes (61, 71). The inner volumes communicate with exterior through the orifices, where the inner volumes have flat or cylindrical shape. Average distance between sealing edges is three times greater than a maximum width of the partition. Walls forming the inner volumes are formed of synthetic materials. The volumes are sized for forming an acoustic resonator. Independent claims are also included for the following: (1) an air intake circuit for an internal combustion engine, comprising a pipe (2) a vehicle comprising a cooling radiator.
