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.

1. A method of separating components of the exhaust gas mixture of an internal combustion engine operating with unleaded or leaded gasoline or diesel or natural gas fuel for subsequent re-cycling of pollutant components thereby reducing air pollution generated by the engine and increasing the fuel economy of the engine, said method comprising:effecting a first separation of the exhaust gas mixture into heavier and lighter components wherein the lighter components are primarily combustible pollutants; effecting a second separation in which the heavier components are separated into a first portion comprising substantially carbon dioxide and water vapor for egress to atmosphere and a second portion comprised substantially of combustible pollutants for subsequent combustion in said engine; effecting a separation of the heavier lead, carbon, or sulfur particles from the second portion of the said second separation comprising the heavier combustible gases and 15.about.25 micron size carbon particles; providing means for priodical and automatic removal of the heavier lead, carbon, or sulfur particles; and mixing said second portion of said second separation stage including the combustible 15.about.25 micron size carbon particles with the lighter components effected in the first separation to effect a combustible mixture for re-cycle to said engine.
