Abstract
The present invention provides an exhaust chamber system, comprising a stationary propeller type blade assembly with a nose cone within or adjacent to an expansion chamber, to create a vortex that swirls exhaust gas towards the outlet. The resultant vacuum within the exhaust chamber aids in scavenging an internal combustion engines exhaust gases, and in reducing system back pressure The exhaust chamber maintains the sound level of the exhaust within acceptable limits, while delivering improved horsepower, torque, and/or fuel efficiency over standard and other performance mufflers.
Claims22
A high performance propulsion chamber system for exhausting combustion gases comprising:
- a shell;
- an expansion chamber tube coaxially attached to said shell;
- a sleeve in said shell;
- sound suppression materials in said sleeve;
- said expansion chamber tube being perforated with aperatures to about 40-80% porosity;
- and
- an inlet flange tube subassembly fastened to said shell in communication with said expansion chamber tube;
- a stationary propeller type blade assembly arranged in said inlet flange;
- and
- a nose cone attached to said stationary propeller type blade assembly.
A device for increasing the horsepower, torque, fuel efficiency, and improving sound performance of an internal combustion engine by lowering back pressure of exhaust gases exerted on said engine, wherein said device comprises:
- a high performance propulsion exhaust chamber system having:
- an expansion chamber tube;
- a shell coaxially attached to said expansion chamber tube wherein an interior of said shell and an exterior of said expansion chamber tube form a sound suppression sleeve containing sound suppression material;
- wherein said expansion chamber tube is made of stainless steel and perforated with apertures, said expansion chamber being in communication with said sound suppression sleeve;
- an inlet flange tube subassembly being attached with fasteners to an inlet flange of said shell of said expansion chamber such that an inlet tube interior is in communication with said expansion chamber, wherein a stationary propeller type blade assembly with a nose cone is inserted between said inlet flange tube subassembly and said expansion chamber tube such that said stationary propeller type blade assembly with said nose cone is capable of swirling the exhaust gas when said exhaust gas passes from said inlet flange tube into said expansion chamber;
- and
- wherein said stationary propeller type blade assembly with said nose cone spins said exhaust gas to facilitate its passage through said expansion chamber, and through an outlet tube of said expansion chamber.
