Abstract
An engine induction system resonator that is designed to minimize emitted engine noise. The resonator includes an enclosed tube that has a first diameter and that defines a resonant chamber therein. The resonator also includes a pipe that has a second diameter smaller than the tube diameter. The pipe extends axially through the tube and has first and second ends that connect to other induction system components to channel inductive air flow therethrough. The pipe defines a plurality of perforated holes distributed along a section of the pipe housed within the tube. The plurality of perforated holes is distributed along the pipe in a manner that minimizes emitted engine noise. The resonator is designed in view of other system components to minimize overall system cost and overall required system implementation area.
