Exhaust gas muffler

Abstract

The present invention includes a muffler for attachment to an engine that includes an inlet for receiving exhaust gases into the muffler, a catalyst assembly located within the muffler, and a fastener tube for fastening the muffler to the engine. A fastener tube cover covers the fastener tube and includes an outlet for exiting exhaust gases. The outlet includes a directional louver that directs the exiting exhaust gases. The fastener tube cover can retain a spark arrestor which maintains maximum spark particle size in the exiting exhaust gases.

       6 . The muffler for attachment to an engine of  claim 1  further comprising an exhaust port and the exhaust port is on a common side with the fastener entrance port.  
   
   
       7 . The muffler for attachment to an engine of  claim 6  wherein the exhaust port and the fastener entrance port face away from the engine.  
   
   
       8 . The muffler for attachment to an engine of  claim 6  wherein the exhaust port and the fastener entrance port are on a common surface of the common side.  
   
   
       9 . The muffler for attachment to an engine of  claim 6  wherein the exhaust port and the fastener entrance port are on a non-coplanar surface.  
   
   
       10 . A muffler comprising: 
 an attacher;    a fastener tube cover;    a spark arrestor;    the attacher retains the fastener tube cover; and    the attacher retains the spark arrestor.    
   
   
       11 . The muffler of  claim 10  wherein the fastener tube cover comprises an outlet for exiting exhaust gases.  
   
   
       12 . A muffler comprising: 
 a fastener tube cover for covering a fastener tube;    the fastener tube cover further comprises an outlet for exhaust gases to exit through; and    the outlet has a directional louver that directs the exiting exhaust gases.    
   
   
       13 . The muffler of  claim 12  wherein the outlet further comprises a deflection plate.  
   
   
       14 . The muffler of  claim 12  wherein the outlet further comprises a hood.  
   
   
       15 . A muffler for attachment to an engine comprising: 
 an inlet for receiving exhaust gases into the muffler;    a catalyst assembly located in the muffler;    a fastener tube for fastening the muffler to the engine;    a fastener entrance port of the fastener tube;    a fastener exit port of the fastener tube;    the fastener entrance port of the fastener tube for facing away from the engine;    the fastener exit port of the fastener tube for facing the engine a fastener tube cover covering the fastener entrance port of the fastener tube;    the fastener tube cover further comprises an outlet for exit of the exhaust gases from the muffler;    the fastener tube cover and the fastener entrance port of the fastener tube are on a common side; and    the outlet has a directional louver that directs the exiting exhaust gases into a desired direction.    
   
   
       16 . The muffler for attachment to an engine of  claim 15  wherein the fastener tube cover can retain a spark arrestor which maintains maximum spark particle size in the exiting exhaust gases.  
   
   
       17 . The muffler for attachment to an engine of  claim 15  further comprising an exhaust port and the exhaust port is on a common side with the fastener entrance port.  
   
   
       18 . The muffler for attachment to an engine of  claim 15  wherein the outlet comprises a hood.  
   
   
       19 . The muffler for attachment to an engine of  claim 18  wherein the hood is removable from the fastener tube cover.  
   
   
       20 . A fastener tube cover for a fastener tube of a muffler having an exhaust port, the fastener tube cover comprising: 
 a fastener tube cover for covering the fastener tube;    an outlet in the fastener tube cover for exiting exhaust gases; and    the outlet comprises a directional louver for directing exiting exhaust gases into a desired direction.    
   
   
       21 . The fastener tube cover for a fastener tube of a muffler having an exhaust port of  claim 20  wherein the fastener tube cover can retain a spark arrestor.
