Description
- 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.
- 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.
- 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.
