Method and device for exhaust gas management

Abstract

A system and method for increasing the performance of an internal combustion engine having a stock exhaust manifold. An exhaust insert affixed to or positioned downstream from the cylinder exhaust ports, in the exhaust conduits, in the stock manifold, in the collector, before or after the catalytic converter, before or after any Y-pipe, or any location in the exhaust system. The exhaust insert having a pre-determined size and shape to optimize performance, including, but not limited to, fuel efficiency, emissions, and power.

1 . A method for increasing engine performance of an internal combustion engine having a stock exhaust system; comprising:
 providing at least one exhaust insert, wherein said at least one exhaust insert has a volume and has an outside diameter approximately equal to 50% to about 95% of the diameter of the stock exhaust system where the exhaust insert is located; and   affixing said at least one exhaust insert into said stock exhaust system between a cylinder exhaust port and a exhaust tip.   
     
     
         2 . The method of  claim 1 , wherein said stock exhaust system includes at least one conduit. 
     
     
         3 . The method of  claim 1 , wherein said stock exhaust system includes a collector. 
     
     
         4 . The method of  claim 2 , wherein said at least one exhaust insert is located inside the at least one conduit. 
     
     
         5 . The method of  claim 3 , wherein said at least one exhaust insert is located inside said collector. 
     
     
         6 . The method of  claim 2 , wherein said exhaust insert has a first and a second end and is affixed to said conduit at a second end. 
     
     
         7 . The method of  claim 1 , wherein said exhaust insert is suspended inside a collar by cross-members. 
     
     
         8 . The method of  claim 7 , wherein said collar is in complementary engagement with an internal surface of said exhaust system. 
     
     
         9 . An exhaust system for increasing the engine performance of an internal combustion engine having a stock exhaust system, wherein said stock exhaust system includes a flange, conduit and a collector, comprising:
 at least one conduit interposed between said flange and said collector;   an elongated body having a defined volume including a first and second end; and   wherein said second end of said elongated body is affixed downstream of said conduit and extends into said collector so that exhaust gas from said internal combustion engine must travel around said exhaust system.   
     
     
         10 . The exhaust system of  claim 9 , wherein said exhaust insert is conical in shape. 
     
     
         11 . The exhaust system of  claim 9 , wherein said exhaust insert has an outside diameter equaling approximately 50% to about 95% of the internal diameter of the exhaust system where the exhaust insert is located. 
     
     
         12 . The exhaust system of  claim 9 , further comprising a collar inserted into said exhaust system, wherein said exhaust insert is suspended within said collar. 
     
     
         13 . The exhaust system of  claim 12 , further comprising a servo motor attached to said collar, wherein said collar is moveable within said exhaust system based on the throttle position to maximize engine performance. 
     
     
         14 . A method of increasing performance in an internal combustion engine having a stock exhaust system; comprising:
 providing a stock exhaust system for the removal of exhaust gas from said internal combustion engine;   analyzing the stock exhaust system in order to determine location and number of exhaust inserts to optimize engine performance;   providing multiple exhaust inserts having an elongated body;   locating the multiple exhaust inserts into said stock exhaust system to optimize engine performance; and   positioning the multiple exhaust inserts in series both before and after a catalytic converter.   
     
     
         15 . The method of  claim 15 , further comprising installing an exhaust insert into said stock exhaust system at each collector. 
     
     
         16 . The method of  claim 15 , further comprising installing an exhaust insert into said stock exhaust system at a Y-pipe. 
     
     
         17 . The method of  claim 14 , wherein at least one said exhaust insert is suspended in a collar and moveable. 
     
     
         18 . The method of  claim 16 , further comprising installing an exhaust insert into at least one conduit leading from cylinder exhaust ports. 
     
     
         19 . The method of  claim 14 , further comprising dynamically adjusting the location of at least one exhaust insert within said stock exhaust system during use to optimize engine performance. 
     
     
         20 . The method of  claim 14 , wherein said dynamic movement is achieved using servos in communication with said exhaust insert.
