Description:
BACKGROUND  
       [0001]     Vehicular exhaust mufflers typically include a tubular outer shell defining an oval or circular cross section and a pair of opposed heads mechanically connected to the shell. The shell is generally formed from one or more sheets of metal that are wrapped into the tubular configuration and are secured by a longitudinally extending seam.  
         [0002]     The internal configurations of mufflers have been varied and have been determined both by the available space available and the particular characteristics of the sound produced by the exhaust gases of a specific engine. The prior art muffler may include an array of tubes extending between and connected to the inlet and outlet. These tubes may communicate with one or more expansion chambers defined by a baffle within the muffler. The size of the tuning tubes and the resonating chambers are selected in accordance with the frequency of the noise to be attenuated.  
       SUMMARY  
       [0003]     The present invention includes a muffler that includes a turbine to rotate longitudinal elements. A portion of the longitudinal elements are located within the muffler cover while the remaining portion of the longitudinal elements is positioned outside of the muffler cover.

     DETAILED DESCRIPTION  
       [0011]      FIG. 1  shows a muffler cover  100  to cover the internal muffler parts. The muffler cover  100  includes a muffler neck  150  to allow the engine gases to enter the muffler, a muffler enclosure  154  to contain the engine gas and conduct the engine gas to the outlet of the muffle and away from  
         [0012]     The vehicle which could be an automobile, a tractor, a motorcycle or a truck, and a sloping portion  152  to connect the muffler neck  150  with the muffler enclosure  152 . The end or outlet of the muffler cover  100  is open to allow the exhaust gas to escape to the atmosphere. The muffler cover  100  is attached to an exhaust frame which includes a longitudinal frame  102  and perpendicular frames  104 ,  106 . by fasteners  160 , These fasteners  160  could be bolts to clamp the muffler enclosure  154  to the longitudinal frame  102 . The longitudinal frame  102  extends thought the outlet of the muffler cover  100  to support the longitudinal element  170 . Connected between the perpendicular frame  104  and the perpendicular frame  106  is a shaft  140  to allow rotation of turbine  120  and longitudinal element  170 .  FIG. 1  shows  4  longitudinal element  170 ; six or any number could be used. The turbine  120  is located between the perpendicular frame  104  and the perpendicular frame  106 . The shaft  140  is connected to perpendicular frame  104  and perpendicular frame  106  by fasteners  162 . The longitudinal element  170  is in a spaced relation to shaft  140  and may be a cylinder. The longitudinal element  170  is connected to the shaft  140  by spacers  130 . A portion of longitudinal element  170  is covered by muffler enclosure  154  and the remaining portion of longitudinal element  170  extends through the outlet of the muffler  170 . The spacer  130   s  connected to the turbine  120  by support element  110  by fasteners  164 . Multiple support elements  110  are shown in  FIG. 1 . The shape of spacer  130  and the distance from longitudinal element  170  to shaft  140  determines the spaced relationship. As shown, longitudinal element  170  is a cylinder, but other shapes are possible such as a rectangle or a triangle as shown in  FIG. 5 . The rotation of these longitudinal elements  170  promote the flow of exhaust gases from the muffler and motor by mixing fresh air with the exhaust gases. A turbine  120  having turbine element  122  which extends from turbine  120  is rotated by the hot gases from the engine of the vehicle enter from muffler neck  150  and pass into the muffler enclosure  154  and then pass through the turbine  120 . The turbine  120  is positioned within the muffler enclosure  154 . The diameter of the turbine  120  is less than the internal diameter of the muffler enclosure  154  so that the turbine  120  can freely rotate on shaft  140  but prevents the hot gas from bypassing the turbine  120 . The hot gases are forced to pass through the turbine  120  thereby turning the turbine  120 .  
         [0013]     As the gases pass though the turbine  120 , the hot gases turn the turbine  120  and the longitudinal element  170  by virtue of the connection to the shaft  140 , spacer  130  and support element  110 .  
         [0014]      FIG. 3  shows the output of the muffler while  FIG. 4  shows the input of the muffler.  
         [0015]      FIG. 2  show another embodiment of the present invention and shows a muffler cover  200  to cover the internal muffler parts. The muffler cover  200  includes a muffler neck  250  to allow the engine gases to enter the muffler, a muffler enclosure  254  to contain the engine gas and conduct the engine gas to the outside of the vehicle which could be a automobile, a tractor, a motorcycle or a truck, and a sloping portion  252  to connect the muffler neck  250  with the muffler enclosure  254 . The output of the muffler cover  200  is open to allow the exhaust gas to escape to the atmosphere. The muffler cover  200  is attached to an exhaust frame which includes a longitudinal frame  202  and perpendicular frames  204 ,  206 . by fasteners  260 , These fasteners  260  could be bolts to clamp the muffler enclosure  254  to the longitudinal frame  202 . Connected between the perpendicular frame  204  and the perpendicular frame  206  is a portion of the shaft  240  to allow rotation of turbine  220  and longitudinal element  270 . The turbine  220  is not positioned between the perpendicular frame  204  and the perpendicular frame  206  but is located with a spaced relation to perpendicular frame  206  by extending the shaft  240 . The shaft  140  is connected to perpendicular frame  204  and perpendicular frame  206  by fasteners  262 . The longitudinal element  270  is in a spaced relation to shaft  240  and may be a cylinder or a plurality of cylinders. The longitudinal element  270  is connected to the shaft  240  by spacers  230 .  FIG. 2  shows shorter longitudinal elements  270  than the corresponding longitudinal element  270 . A portion of the longitudinal element  270  is positioned within the muffler enclosure  252 , and the remaining portion of the longitudinal element  270  extends beyond the outlet of the muffler. The result is the longitudinal element  202  and the perpendicular frames  204  and  206  are within the muffler enclosure  254 . The shape of spacer  230  and the distance from longitudinal element  270  to shaft  240  determines the spaced relationship. As shown, longitudinal element  270  is a cylinder but other shapes are possible such as a rectangle or a triangle. The rotation of these longitudinal elements  270 , which may be four, six or any number promote the flow of exhaust gases from the muffler and motor by mixing fresh air with the exhaust gases. A turbine  220  having turbine element  222  which extends from turbine  220  is positioned within the muffler enclosure  254 . The diameter of the turbine  220  is less than the internal diameter of the muffler enclosure  254  so that the turbine  220  can freely rotate on shaft  240  but prevents the hot gas from bypassing the turbine  220 . The hot gases are forced to pass through the turbine  220  thereby turning the turbine  220 .  
         [0016]     The hot gases from the engine enter from muffler neck  250  and pass into the muffler enclosure  254  and then pass through the turbine  220 . As the gases pass though the turbine  220 , the hot gases turn the turbine  220  and the longitudinal element  270  by virtue of the connection to shaft  240  and spacer  230 .
