Estimating the term…
An air routing system, especially an air intake system of an internal combustion engine, which makes optimal use of available installation space by integrating a bypass channel (25) into an air intake module (10). The volume of the bypass channel also provides an acoustic shield for the collector chamber or plenum (22). The free area (13) behind the mounting flange (11) that is required for screwing in mounting bolts in order to mount the air intake module (10) is used by an air intake hood (14) which can be installed on the filter housing (15) after the air intake module has been mounted. This assures that there is a greater volume available in the filter housing (15), thereby reducing the noise at the inlet opening of the air intake module.
An air intake module for an internal combustion engine comprising a series of air conduction channels and volumes for conducting the air from a raw air inlet to intake pipe outlets in a mounting flange having seats for attachment to a cylinder head of the internal combustion engine, wherein the air conduction channels are formed by walls of the intake module, and a portion of the channel forming walls is formed by at least one hood, and said hood projects into a clearance provided for assembly tools.
