Abstract
Official abstract text for this publication.
An air induction system for attenuating sound produced by an engine, a housing defining a working chamber for attenuating sound produced by the engine. The air induction system further includes a tube having a first end extending into the working chamber and a second end to be in fluid communication with the engine. The air induction system further includes a first flange radially extending from the tube and disposed in the working chamber. The tube, the housing and the first flange cooperate to define a resonator operable to attenuate sound produced by the engine.
First claim
Opening claim text (preview).
What is claimed is: 1. An air induction system for attenuating sound produced by an engine, the air induction system comprising: a housing defining a working chamber for attenuating sound produced by the engine; a tube having a first end extending into the working chamber and a second end to be in fluid communication with the engine; and a first flange radially extending from the tube and disposed in the working chamber; wherein the tube, the housing and the first flange cooperate to define a resonator operable to attenuate sound produced by the engine; and a ring axially extending from the first flange. 2. The air induction system of claim 1 , wherein the first flange is disposed adjacent the first end. 3. The air induction system of claim 1 , wherein the housing is an air filter box housing and further wherein an air filter is disposed in the housing. 4. The air induction system of claim 1 , wherein the housing includes an inlet in fluid communication with a source of inlet air and an outlet in fluid communication with the engine. 5. An air induction system for attenuating sound produced by an engine, the air induction system comprising: a housing defining a working chamber for attenuating sound produced by the engine, the housing including an inlet and an outlet; a filter disposed in the working chamber between the inlet and outlet of the housing; a tube having a first end extending into the working chamber and a second end to be in fluid communication with the engine; and a first flange radially extending from the tube and disposed in the working chamber; wherein the housing, the tube and the first flange cooperate to define a resonator operable to attenuate sound produced by the engine; and a ring axially extending from the first flange. 6. The air induction system of claim 5 , wherein the first flange is disposed adjacent the first end. 7. A method of attenuating sound produced by an engine, the method comprising: providing a housing defining a working chamber for attenuating sound produced by the engine, a tube having a first end extending into the working chamber and a second end to be in fluid communication with the engine, and a first flange radially extending from the tube and disposed in the working chamber; and a ring axially extending from the first flange; attenuating sound produced by the engine with a resonator cooperatively defined by the tube, the housing and the first flange. 8. The method of claim 7 , further comprising: placing an air filter in the housing; and filtering a source of intake air with the filter.
