Exhaust Gas-Discharging Device of Vehicle

Abstract

The present invention relates to an exhaust gas-discharging device for exhausting the burned gas utilized in an internal combustion engine, and more particularly, to an exhaust gas-discharging device of a vehicle for exhausting the burned gas to a muffler tail pipe, provided in an exhaust gas-discharging path of a vehicle, using airflow to improve fuel efficiency and torque of the vehicle. The exhaust gas-discharging device includes first and second fixed vanes ( 30 and 40 ), which are formed in the form of streamline shapes by cutting a side of a tail pipe ( 20 ) formed at the rear end of a muffler ( 10 ), provided on an exhaust gas-discharging path through which exhaust gas discharged from an engine of a vehicle passes, and which the same are bent inward, and spaced apart from each other to face each other, and a circulation exhaust gas-discharging device ( 50 ) having a pipe body ( 52 ) welded to the tail pipe and communicated with the first and second fixed vanes ( 30 and 40 ) to seal the first and second fixed vanes ( 30 and 40 ) from ambient air.

1 . An exhaust gas-discharging device of a vehicle comprising: 
 first and second fixed vanes ( 30  and  40 ), which are formed in the form of streamline shapes by cutting a side of a tail pipe ( 20 ), provided on an exhaust gas-discharging path of a muffler ( 10 ) through which exhaust gas discharged from an engine of a vehicle passes, and which the same are bent inward, and are spaced apart from each other to face each other; and    a circulation exhaust gas-discharging device ( 50 ) having a pipe body ( 52 ) welded to the tail pipe and communicated with the first and second fixed vanes ( 30  and  40 ) to seal the first and second fixed vanes ( 30  and  40 ) from ambient air.    
   
   
       2 . The exhaust gas-discharging device of a vehicle as set forth in  claim 1 , further comprising a plurality of tail pipes, in which circulation exhaust gas-discharging devices ( 50 ) respectively include a tail pipe ( 20 ) in which first and second fixed vanes ( 30  and  40 ) are formed and a pipe body ( 52 ) for surrounding the first and second fixed vanes ( 30  and  40 ) and connected to the exhaust side of a muffler in parallel relation with each other.  
   
   
       3 . The exhaust gas-discharging device of a vehicle as set forth in  claim 1 , wherein the circulation exhaust gas-discharging device ( 50 ) includes the tail pipe ( 20 ), in which first and second fixed vanes ( 30  and  40 ) are formed, and the pipe body ( 52 ) for surrounding the first and second fixed vanes ( 30  and  40 ), and is coupled with the exhaust side of a muffler ( 10 ) by a clamp ( 54 ).
