Catalytic converter muffler

Abstract

A catalytic converter muffler has a tubular housing with an inlet and outlet, and a baffle chamber intermediate the length thereof, a generally cylindrical catalytic converter supported in the tubular housing adjacent the inlet and a pair of tubular baffle members are disposed in the baffle chamber. An outlet offset baffle ring closing the inlet end of one of the baffles to block flow of gas thereinto, and an inlet offset baffle element closes the outlet end of the other of the baffles to block flow of gas outwardly to the outlet end of the housing. A power bar is provided in the outlet baffle closely adjacent the outlet end thereof to interrupt the harmonic waves of the base in the outlet baffle. The exhaust gas flows from the catalytic converter into the other baffle and thence through the perforations into the outlet baffle through the perforations in the inlet baffle and through the perforations in the outlet baffle.

1 . In a catalytic converter muffler, the combination comprising:
 (a) a tubular housing having inlet and outlet end portions, and a baffle chamber intermediate the length thereof;   (b) a catalytic converter supported in said tubular housing adjacent said inlet end portion, said converter providing a flow passage therethrough;   (c) a pair of tubular baffle members disposed in said baffle chamber and extending in parallel relationship spaced from said housing, said baffle members having a substantially uniform cross section and perforations along the length thereof;   (d) an outlet offset baffle ring closing the inlet end of one of said baffle members to block flow of gas thereinto from said catalytic converter;   (e) an inlet offset baffle ring closing the outlet end of the other of said baffle members to block flow of gas outwardly therefrom to said outlet end of said housing;   (f) a power bar in said outlet end portion closely adjacent the outlet end thereof to interrupt the harmonic waves of the gas in said outlet;   (g) whereby exhaust gas flows from said catalytic converter into the open inlet end of said other baffle member, is blocked by said outlet baffle ring, said gas then flowing through said perforations into said baffle chambers into said one baffle member through the perforations in said baffle member, said gas then flowing outwardly through the outlet end of said baffle member.   
   
   
       2 . The catalytic peripheral converter muffler in accordance with  claim 1  wherein said baffle members have a peripheral wall with an arcuate section and a generally linear section, said linear sections being opposed. 
   
   
       3 . The catalytic converter muffler in accordance with  claim 1  wherein there is included at least one tie bar having its ends secured to said baffle members and baffle rings to assemble said baffle members and rings. 
   
   
       4 . The catalytic converter muffler in accordance with  claim 1  wherein there are included an expanding funnel-shaped inlet members prior to said catalytic converter, and a reducing funnel shaped outlet member directing the gases into said other baffle member. 
   
   
       5 . The catalytic converter muffler in accordance with  claim 3  wherein a pair of tie bars are diametrically spaced apart. 
   
   
       6 . The catalytic converter muffler in accordance with  claim 1  wherein said baffle rings are of generally circular ring-like said baffle rings having offset passages therethrough. 
   
   
       7 . The catalytic converter muffler in accordance with  claim 1  wherein said power bar extends transversely of said outlet end portion.
