Automotive exhaust system

Abstract

The automotive exhaust system includes a plurality of exhaust pipes that feed into a common collector. The collector includes a venturi at the point where the exhaust gases enter the collector from the multiple exhaust pipes. The exhaust gases accelerate through the venturi by virtue that the venturi has a cross-sectional area smaller than that of the exhaust pipes and the collector. A plurality of vanes located in the venturi further accelerate the exhaust gases into a spinning vortex along the interior surface of the main body of the collector to efficiently and quickly expel the exhaust gases out from within the automotive exhaust system. The diameter of the venturi relative to the collector is specific to each diameter of tubing as matched with the corresponding vehicle specifications.

1 . An exhaust system, comprising:
 a plurality of exhaust pipes at a proximal end of the exhaust system for receiving internal combustion engine exhaust, the exhaust pipes having a combined cross-sectional area;   a collector at a distal end of the exhaust system and having a cross-sectional area;   a venturi disposed between and fluidly connecting the exhaust pipes and collector, wherein a cross-sectional area thereof is less than either the collector cross-sectional area or the combined exhaust pipes cross-sectional area; and   a vane fixed to an inner wall of the venturi.   
   
   
       2 . The exhaust system of  claim 1 , wherein the vane comprises an arced vane which matches the inner wall of the venturi. 
   
   
       3 . The exhaust system of  claim 1 , wherein the vane is angled relative to the adjacent inner wall of the venturi. 
   
   
       4 . The exhaust system of  claim 1 , comprising a plurality of vanes fixed to the inner wall of the venturi. 
   
   
       5 . The exhaust system of  claim 4 , comprising at least one vane corresponding to each exhaust pipe. 
   
   
       6 . The exhaust system of  claim 5 , wherein each vane is approximately centered relative to its corresponding exhaust pipe. 
   
   
       7 . The exhaust system of  claim 1 , wherein the collector and venturi are integrally formed from a single piece of tubing. 
   
   
       8 . An exhaust system, comprising:
 a plurality of exhaust pipes at a proximal end of the exhaust system for receiving internal combustion engine exhaust, the exhaust pipes having a combined cross-sectional area;   a collector at a distal end of the exhaust system and having a cross-sectional area;   a venturi disposed between and fluidly connecting the exhaust pipes and collector, wherein a cross-sectional area thereof is less than either the collector cross-sectional area or the combined exhaust pipes cross-sectional area; and   at least one vane corresponding to each exhaust pipe fixed to an inner wall of the venturi.   
   
   
       9 . The exhaust system of  claim 8 , wherein the vane comprises an arced vane which matches the inner wall of the venturi. 
   
   
       10 . The exhaust system of  claim 8 , wherein the vane is angled relative to the adjacent inner wall of the venturi. 
   
   
       11 . The exhaust system of  claim 8 , wherein each vane is approximately centered relative to its corresponding exhaust pipe. 
   
   
       12 . The exhaust system of  claim 8 , wherein the collector and venturi are integrally formed from a single piece of tubing. 
   
   
       13 . An exhaust system, comprising:
 a plurality of exhaust pipes at a proximal end of the exhaust system for receiving internal combustion engine exhaust, the exhaust pipes having a combined cross-sectional area;   a collector at a distal end of the exhaust system and having a cross-sectional area;   a venturi disposed between and fluidly connecting the exhaust pipes and collector, wherein a cross-sectional area thereof is less than either the collector cross-sectional area or the combined exhaust pipes cross-sectional area; and   at least one vane corresponding to each exhaust pipe fixed to an inner wall of the venturi, wherein each vane is approximately centered relative to its corresponding exhaust pipe and comprises an arced vane which matches the inner wall of the venturi and is angled relative to the adjacent inner wall of the venturi.
