Mr. Bo

Thanks for the patent reminder. Thought I would post the abstract here with the inventors and company name for all to see. I am not sure if this has been posted here before or not, and I am not about to read through the long list of posts to find out. All you have to do is enter the patent number into this site to get all the gory details:

Air turbine for combustion engine


Abstract
An air turbine apparatus for use with a combustion engine either as a muffler or as an air intake device is comprised of a housing defining an expansion chamber and an airfoil positioned within the housing. The airfoil includes a central aperture extending longitudinally therethrough that is in fluid communication with both the inlet and the outlet of the housing. The airfoil is configured to allow gases flowing through the inlet to flow between the outer edge of the airfoil and the housing and through the aperture of the airfoil. In addition, the air traveling through the housing is caused to spin as it travels through the housing. This rotational flow increased the rate of flow of gases through the air turbine device. A chop core is provided between the airfoil and the outlet of the housing to encourage turbulent flow of gases without restricting flow to produce a muffling effect and thus a dampening of noise from the combustion engine.
