Abstract
Methods and apparatuses are provided for an air inlet duct of an internal combustion engine. The air inlet duct includes a tubular housing. An inner wall has a plurality of perforations. The inner wall is disposed within the tubular housing such that the tubular housing includes at least two flow passages. A valve set is associated with a first flow passage of the at least two flow passages. The valve set selectively controls airflow through the first flow passage such that the first flow passage functions in a least one of a pass-through mode and a tuning mode.
Claims19
An air inlet duct of an internal combustion engine, the air inlet duct comprising:
- a tubular housing;
- an inner wall having a plurality of perforations, wherein the inner wall is disposed within the tubular housing such that the tubular housing includes at least two flow passages;
- and
- a valve set associated with a first flow passage of the at least two flow passages, wherein the valve set selectively controls airflow through the first flow passage such that the first flow passage functions in a least one of a flow-through mode and a tuning mode.
An air induction system for an internal combustion engine, comprising:
- an air cleaner;
- and
- an air inlet duct coupled to the air cleaner, the air inlet duct comprising:
- a tubular housing;
- an inner wall having a plurality of perforations, wherein the inner wall is disposed within the tubular housing such that the tubular housing includes at least two flow passages;
- and
- a valve set associated with a first flow passage of the at least two flow passages, wherein the valve set selectively controls airflow through the first flow passage such that the first flow passage functions in a least one of a pass-through mode and a tuning mode.
A vehicle, comprising:
- an engine system;
- and
- an air inlet duct coupled to the engine system, the air inlet duct comprising:
- a tubular housing;
- an inner wall having a plurality of perforations, wherein the inner wall is disposed within the tubular housing such that the tubular housing includes at least two flow passages;
- and
- a valve set associated with a first flow passage of the at least two flow passages, wherein the valve set selectively controls airflow through the first flow passage such that the first flow passage functions in a least one of a pass-through mode and a tuning mode.
