Exhaust gases from an internal combustion engine operating with leaded or unleaded gasoline or diesel or natural gas, are used for energizing a high-speed gas turbine. The convoluting gas discharge causes a first separation stage by stratifying of heavier and lighter exhaust gas components that exit from the turbine in opposite directions, the heavier components having a second stratifying separation in a vortex tube to separate combustible pollutants from non-combustible components. The non-combustible components exit a vortex tube open end to atmosphere. The lighter combustible, pollutants effected in the first separation are bubbled through a sodium hydroxide solution for dissolving the nitric oxide, formaldehyde impurities in this gas stream before being piped to the engine air intake for re-combustion, thereby reducing the engine's exhaust pollution and improving its fuel economy. The combustible, heavier pollutants from the second separation stage are piped to air filter assemblies. This gas stream convoluting at a high-speed through the top stator-vanes of the air filters, centrifugally separates the coalescent water, aldehydes, nitrogen dioxides, sulfates, sulfur, lead particles which collect at the bottom of the bowl, wherein it is periodically released to the roadway. Whereas, the heavier hydrocarbon, carbon particles are piped through the air filter's porous element to the engine air intake for re-combustion, further reducing the engine's exhaust pollution and improving its fuel economy.

FEDERALLY SPONSORED RELIABILITY AND LIFECYCLE TESTS My patented, "Anti-Pollution System For Automobiles", Experimental Prototype based on U.S. Pat. Nos. 4,235,845; 3,892,070 and 3,861,142 received an US D.O.E Grant Award from its Office of Energy Related Inventions. The Grant was used to demonstrate the Bose System's pollutant gas separation and emission control efficiencies along with the fuel economy achieved, as compared with the OEM Catalytic Converter, as a retrofit application on a new 1979 Model Chrysler Cordoba V8, 5.9 Liter engine capacity test automobile. After completion of the baseline, dynamometer powered tests with the OEM converter at 1,134 and 12,140 service miles, the three-way converter was removed and replaced with the Bose System prototype, leaving all other OEM pollution accessories in place, including the controlled electronic ignition combustion and the exhaust gas re-circulation systems. Eight dynamometer test results, using the 1975 CVSII Federal Test Procedure (FTP), were used to verify the repeatability and lifecycle of the Bose System over 50,000 service-test miles. All tests were performed at the Gulf Research Laboratory, Pittsburgh, Pa. The comparative test results are disclosed later.
