Abstract

Abstract An apparatus used in combination with a gasoline powered internal combustion engine. The apparatus allows a fuel-air inlet charge to be applied into the engine combustion chamber that is comprised of an optimized mixture of gasoline, air and unburned hydrocarbon exhaust gases. The apparatus is comprised of four elements that are synergistically combined with existing engine and engine-related components. The four elements include a thermic reactor, a catalytic gas injector, a thermic reactor exhaust filter, and a fuel regulator/restrictor. The thermic reactor supplies heated clean air and exhaust gases to the catalytic gas injector where the clean air and exhaust gases are mixed. The mixed gas together with a regulated quantity of gasoline supplied from the fuel regulator/restrictor are applied to the carburetor or fuel injection system. The fuel-air mixture improves the thermal efficiency of the engine, thereby reducing fuel consumption, and reducing air-contaminating exhaust emissions.
