Abstract
An exhaust processor includes a housing formed to include an interior region and a partition or first spark arrester that partitions the interior region into chambers and includes a wool filter formed to include an opening. The wool filter is positioned to filter unburned carbon particles from combustion product generated by a vehicle engine. The exhaust processor further includes an outer conduit that extends through the opening formed in the wool filter and is formed to include a passage and an inner conduit that extends into the passage and is formed to include an opening through which unburned carbon particles flow from inside the inner conduit to impinge against the outer conduit so that the outer and inner conduits operate as a second spark arrester.
Claims20
An exhaust processor for processing combustion product comprising
- a housing formed to include an interior region and formed to include a housing inlet through which combustion product enters the interior region and a housing outlet through which combustion product exits the interior region,
- a partition including a first plate formed to include a first opening, a second plate formed to include a second opening and cooperating with the first plate to form a space therebetween, and wool positioned to lie in the space between the first and second plates, the first and second plates cooperating to partition the interior region into a first chamber and a second chamber, the wool being configured to filter unburned carbon particles entrained in combustion product flowing from the first chamber through the first opening, the wool, and the second opening to the second chamber so that the partition operates as a first spark arrester, the first and second plates and the wool cooperating with one another to form a third opening, and
- a second spark arrester including an outer conduit extending through the third opening and formed to include a first passage and an outlet and an inner conduit positioned to lie in the first passage and formed to include a second passage and a fourth opening so that unburned carbon particles entrained in combustion product flows from the second passage through the fourth opening to impinge against the outer conduit, the outer conduit being arranged to dispense combustion product through its outlet into the first chamber without introducing combustion product directly from the first passage into the space between the first and second plates.
An exhaust processor for processing combustion product comprising
- a housing formed to include an interior region and a housing inlet through which combustion product enters the interior region, the housing including a side wall formed to include a housing outlet through which combustion product exits the interior region,
- a first partition,
- a second partition cooperating with the first partition to partition the interior region into an inlet chamber, an intermediate chamber formed between the first and second partitions, and an outlet chamber, the second partition being configured to filter unburned carbon particles from combustion product flowing from the inlet chamber through the second partition to the intermediate chamber so that the second partition operates as a first spark arrester, the second partition being formed to include a first opening,
- a second spark arrester including an outer conduit extending from the inlet chamber through the first opening to the intermediate chamber and formed to include a first passage and an inner conduit positioned to lie in the first passage in coaxial relation to the outer conduit relative to a first axis, the outer conduit being mounted to the first and second partitions, the inner conduit being formed to include a second opening so that unburned carbon particles entrained in combustion product flows from the second passage through the second opening to impinge against the outer conduit, and
- a silencer including sound-absorbent material, a sleeve formed to include a third passage, and a conduit positioned to lie in the third passage in coaxial relation to the sleeve relative to a second axis, the sleeve and the conduit of the silencer cooperating to form a space therebetween, the sound-absorbent material being positioned to lie in the space, the sound-absorbent material, the sleeve, and the conduit of the silencer extending from the outlet chamber through the housing outlet so that combustion product flows from the outlet chamber through the silencer to exit the exhaust processor, the first and second axes being positioned to lie in generally perpendicular relation to one another.
