US Patent:

6539917, Apr 1, 2003

Filed:

May 3, 2001

Appl. No.:

09/848494

Inventors:

Christopher Edward Shaw - Canton MI
James T. Dumas - Clinton Township MI
James John Kempf - Canton MI

Assignee:

Visteon Global Technologies, Inc. - Dearborn MI

International Classification:

F02M 300

US Classification:

1233391, 181229

Abstract:

An arrangement for reducing noise produced by an engine idle air bypass valve and passage includes positioning an acoustic diverter at the end of the air bypass passage to force the noise away from exterior surfaces of a downstream chamber and toward the internal cavities of the engine such as a cylinder head. The diverter of the present invention reduces noise without causing restriction of air flow through the air bypass passage.

Abstract:

An in-line resonator for an air induction system of an internal combustion engine is provided. The system includes a resonator housing, an upstream duct, a downstream duct, a conduit, a partition, and a sleeve. The conduit extends through the resonator housing connecting the upstream duct and the downstream duct. The partition is moveable within the resonator housing and divides the housing into an upstream chamber and a downstream chamber. The downstream chamber, the conduit, and the downstream sleeve cooperate to form a first Helmholtz resonator that is in fluid communication with the downstream duct. The upstream chamber, the conduit, and the upstream sleeve cooperate to form a second Helmholtz resonator that is in fluid communication with the upstream duct. Further, a means is provided to axially move the partition to vary the volume of the chambers concurrently with the length and/or area of the passages.

Assignee:

Visteon Global Technologies, Inc. - Van Buren Township MI

International Classification:

F02B 77/04
B65D 17/00

US Classification:

123198E, 181229

Abstract:

An air induction system for a motor vehicle, having a pair of conduits fluidly connecting an engine to the ambient air and a housing located between the pair of conduits. The housing includes side walls and a top wall defining a chamber. A baffle plate for attenuating noise is positioned within the chamber adjacent to the top wall. Additionally, the baffle plate defines a plurality of openings extending therethrough.

International Classification:

F02M 35/10

US Classification:

12318457, 181229

Abstract:

A modular air induction system for a vehicle is provided. The air induction system includes a housing, a partition, and a plurality of holding members. The housing defines a chamber and includes an opening in fluid communication with the chamber. A partition is located within the housing to separate the chamber into a first and second volume thereby changing attenuation characteristics of the chamber. The partition is fixed within the chamber by at least one first holding member, thereby defining a first partition location. In addition, at least one second holding member is located within the housing and is adapted to receive the partition, thereby defining a second partition location.

Abstract:

A resonator for a vehicle is provided, including a housing having at least one chamber formed therein. The housing has at least one aperture formed in a wall thereof. The housing is in fluid communication with an air conduit of the vehicle. At least one flexible member is disposed within the chamber of the housing. The flexible member includes an outer portion and an inner extension protruding from the outer portion which vibrates to attenuate low frequency sound energy transmitted from the air conduit.
