Particle matter catalyst inserted muffler

Abstract

A particle matter catalyst inserted muffler may include a first exhaust gas discharge pipe penetratively joined to baffles and protruding in a predetermined length from a rear baffle for guiding outside an exhaust gas introduced into a muffler housing, and a second exhaust gas discharge pipe that fits in an end portion of the first exhaust gas discharge pipe while penetratively fitting in an end plate that is inserted into one opening of the muffler housing toward the rear bavbffle to be joined to the muffler housing.

1 . A particle matter catalyst inserted muffler, comprising:
 a first exhaust gas discharge pipe penetratively joined to baffles and protruding in a predetermined length from a rear baffle for guiding outside an exhaust gas introduced into a muffler housing; and   a second exhaust gas discharge pipe that fits in an end portion of the first exhaust gas discharge pipe while penetratively fitting in an end plate that is inserted into one opening of the muffler housing toward the rear baffle to be joined to the muffler housing.   
   
   
       2 . The particle matter catalyst inserted muffler according to  claim 1 , wherein a distance between the rear baffle and the end plate is longer than the predetermined length of the first exhaust gas discharge pipe. 
   
   
       3 . The particle matter catalyst inserted muffler according to  claim 1 , wherein a gasket is disposed at a space where the first exhaust gas discharge pipe and the second exhaust gas discharge pipe are overlapped each other. 
   
   
       4 . The particle matter catalyst inserted muffler according to  claim 3 , wherein the second exhaust gas discharge pipe includes:
 an extension portion having a diameter larger than a diameter of the first exhaust gas discharge pipe and the gasket being closely contacted therebetween; and   an assembly guide formed in a front side of the extension portion wherein a diameter of the assembly guide expands out from the extension portion.   
   
   
       5 . The particle matter catalyst inserted muffler according to  claim 4 , wherein the second exhaust gas discharge pipe further includes a stopper portion formed in a rear side thereof and a diameter of a lower portion thereof is smaller or equal to the diamater of the first exhaust gas discharge pipe. 
   
   
       6 . The particle matter catalyst inserted muffler according to  claim 1 , wherein a plurality of baffles are inserted into the muffler housing to be integrately attached to the muffler housing and a catalyst can is fixedly joined through the baffles.
