Abstract
An exhaust processor has an exhaust tube and a cover mounted for rotation at least partially around the exhaust tube to adjust the tuning frequency of the exhaust processor. A method of operating the exhaust processor is also disclosed.
Claims20
An exhaust processor having a tuning frequency for abatement of acoustic waves at the tuning frequency, the exhaust processor comprising:
- a housing defining an aperture,
- an exhaust tube extending through the aperture into the housing and defining an exhaust tube opening positioned inside the housing for communication of acoustic waves between the housing and the exhaust tube, and
- a cover mounted for rotation at least partially around the exhaust tube over the exhaust tube opening to adjust the tuning frequency of the exhaust processor.
An exhaust processor having a tuning frequency for abatement of acoustic waves at the tuning frequency, the exhaust processor comprising:
- an exhaust tube defining perforations for passage of acoustic waves therethrough, and
- a cover mounted for rotation at least partially around the exhaust tube over a number of the perforations to adjust the tuning frequency of the exhaust processor.
A method of operating an exhaust processor having a tuning frequency for abatement of acoustic waves at the tuning frequency, the method comprising the step of:
- rotating a cover at least partially around an exhaust tube over a number of perforations defined by the exhaust tube to adjust the tuning frequency of the exhaust processor.
