Abstract
An integrated mass air flow sensor/broadband silencer assembly comprises a molded body having a plurality of walls formed therein. The molded body is over-wrapped with a layer of acoustic foam that, together with the plurality of walls, define a plurality of chambers within an interior volume of the assembly. A mass air flow sensor can be inserted into one of the chambers. The chambers are sized and spaced to provide a uniform velocity, low turbulence air flow to the sensor, and a minimally-restricted air flow to an internal combustion engine located downstream of the assembly.
