Abstract
A muffler includes a first tube defining a first inlet for receiving exhaust and a first outlet. The muffler includes a housing defining a tuning chamber. The muffler includes a second tube at least partially received within the first tube. Further, the second tube defines a second inlet disposed within the first tube and a second outlet disposed in fluid communication with the tuning chamber. The muffler further includes a muffler outlet for discharging exhaust from the muffler. Moreover, the first tube and the second tube define an annular passage therebetween. The annular passage is disposed in fluid communication with the first outlet of the first tube and the muffler outlet.
Claims21
A muffler comprising:
- a first tube defining a first inlet for receiving exhaust and a first outlet;
- the first tube having an expanded area such that the first outlet has a greater area than the first inlet;
- a housing defining a tuning chamber;
- a second tube at least partially received within the expanded area of the first tube, the second tube defining a second inlet disposed within the first tube and a primary exhaust path through the second tube, the second tube comprising a second outlet disposed in the tuning chamber;
- and
- a muffler outlet for discharging exhaust from the muffler;
- wherein the first tube and the second tube define an annular passage therebetween and a secondary exhaust path, the annular passage defines the first outlet of the first tube and is in fluid communication with the muffler outlet;
- and
- wherein the primary exhaust path is into the tuning chamber and the secondary exhaust path is through the first outlet and the muffler outlet.

A muffler comprising:
- a housing;
- a first partition wall disposed within the housing, the first partition wall and the housing defining a first tuning chamber therebetween;
- a second partition wall disposed within the housing and spaced apart from the first partition wall, the second partition wall and the housing defining a second tuning chamber therebetween, and wherein the first partition wall, the second partition wall and the housing define an expansion chamber disposed between the first tuning chamber and the second tuning chamber;
- a first tube at least partly received within the housing, the first tube defining a first inlet for receiving exhaust and a first outlet disposed in fluid communication with the expansion chamber;
- the first tube having an expanded area such that the first outlet has a greater area than the first inlet;
- a second tube at least partially received within the expanded area of the first tube, the second tube defining a second inlet disposed within the first tube and a primary exhaust path through the second tube, the second tube comprising a second outlet disposed in the first tuning chamber;
- and
- a third tube defining a third inlet in the expansion chamber and a having a muffler outlet for discharging exhaust from the housing;
- wherein the first tube and the second tube define an annular passage therebetween and a secondary exhaust path, the annular passage the first outlet of the first tube and is in fluid communication with the third inlet;
- and
- wherein the primary exhaust path is into the first tuning chamber and the secondary exhaust path is through the third inlet and the muffler outlet.
