Abstract
A system for reducing noise associated with a compressor of an engine system comprises an intake manifold and a resonator comprising an outlet. The resonator is coupled to, and is positioned adjacent to, the intake manifold. An outlet pipe is in fluid communication with the outlet and the compressor, and a length of the outlet pipe extends from the outlet to the compressor. Positioning the resonator adjacent to the intake manifold reduces the length of the outlet pipe so as to reduce noise associated with air flowing through the outlet pipe.
Claims14
An apparatus for noise reduction in an engine system including a compressor, comprising:
- an intake manifold;
- a first extension extending from a bottom surface of the intake manifold;
- a resonator comprising an inlet and an outlet, the resonator coupled to the first extension;
- an outlet pipe in fluid communication with the outlet and the compressor, a length of the outlet pipe extending from the outlet to the compressor;
- and
- an inlet pipe in fluid communication with the inlet and a clean air source;
- wherein coupling the resonator to the first extension causes the bottom surface to contact the resonator, wherein coupling the resonator to the first extension positions the outlet in close proximity to the compressor, and further comprising a first recess defined by a top surface of the resonator, and a first attachment structure positioned in the first recess, the first attachment structure and the first recess defining a first pocket.
A system for reducing noise associated with a compressor of an engine system, comprising:
- an intake manifold comprising a body;
- a plurality of extensions extending from the body;
- a resonator comprising a top surface, the top surface defining a plurality of recesses;
- an outlet pipe in fluid communication with the resonator and the compressor, a length of the outlet pipe extending from the resonator to the compressor;
- wherein the resonator is positioned under the intake manifold and the resonator is in close proximity to the compressor, wherein the top surface of the resonator is in contact with the intake manifold, wherein the plurality of extensions are configured to interface with the plurality of recesses, the plurality of extensions comprising a first extension, a second extension, and a third extension.
An engine system, comprising:
- a compressor;
- a resonator;
- an outlet pipe coupled to the resonator and the compressor, the outlet pipe providing for air flow from the resonator to the compressor, the outlet pipe comprising an outlet pipe length;
- and
- an intake manifold coupled to, and positioned above, the resonator,
- wherein the position of the resonator relative to the intake manifold causes the resonator to be in close proximity to the compressor, wherein the resonator comprises a top surface, the top surface defining a plurality of recesses, wherein the intake manifold comprises a plurality of extensions, the plurality of extensions configured to interface with the plurality of recesses.
