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.

Appl. No.:

10/022748

Inventors:

James John Kempf - Canton MI

Assignee:

Visteon Global Technologies, Inc. - Dearborn MI

International Classification:

F02M 3512

US Classification:

123198E, 12318461, 2989008

Abstract:

The present invention relates to a component for an internal combustion engine of an automobile having reduced NVH properties. The component has a shell formed with a plastic composite material. The shell defines an inlet port, an outlet port, an outer surface and an inner surface. The inner surface defines an inner cavity to allow air passage to the internal combustion engine. A damping layer is disposed on the outer surface such that damping layer substantially dampens the noise emitted from the component.

International Classification:

B01D045/12

US Classification:

553853, 55396, 55412, 55457

Abstract:

A pre-separator removes contaminants from dirty air and an air intake system of an automobile engine. The pre-separator includes a central body connected to a plurality of vanes, the central body including a leading nose-cone portion and a trailing nose-cone portion. An exit tube defines an outlet that is sized and positioned relative to the central body. The pre-separator is capable of easy packaging within the air intake system, while minimizing the restriction and maximizing horsepower of the engine. In one embodiment, the separation efficiency, the restriction, and acoustic tuning may be selectively controlled for the particular application.

Abstract:

A system that enables enhanced air flow to the air intake of an internal combustion engine having a turbocharger is disclosed. The air induction system includes a plenum or expansion chamber located within the area directly in front of the inlet of the turbocharger. Alternatively, the air induction system may include a diffuser and/or an expansion chamber for reducing the velocity of the air flow within the clean air duct in an area directly in front of the inlet of the turbocharger.
