Abstract:
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 15Ëœ25 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 15Ëœ25 micron size carbon particles with the lighter components effected in the first separation to effect a combustible mixture for re-cycle to said engine.
