Abstract
A method and apparatus are provided for reducing pollutants in the exhaust gases produced from the combustion of a fuel by introducing hydroxyl and associated radicals and oxidizers into at least one of the precombustion and postcombustion gas stream of the combustion engine upstream of the catalytic converter and treating the exhaust gases with the catalytic converter.
Claims20
An apparatus for reducing pollutants from the combustion of a fuel, the apparatus comprising:
- a combustion chamber having a precombustion gas stream to the combustion chamber and a postcombustion gas stream of exhaust from the combustion chamber;
- a large surface area receptacle located in the postcombustion gas stream, the receptacle comprising a housing and a substrate within the housing, the substrate having a large surface area;
- a device for adding hydroxyl radicals to at least one of the precombustion gas stream and the postcombustion gas stream before the termination of the large surface area receptacle.
The apparatus of 6, wherein the water supply inlet passageway is in communication with the postcombustion gas stream.
An apparatus for reducing pollutants in the exhaust gases of a combustion engine having precombustion and postcombustion gas streams comprising:
- a device for generating hydroxyl radicals in communication with at least one of a precombustion gas stream and the postcombustion gas stream;
- a catalytic converter for treating the exhaust gases to at least reduce one pollutant from incomplete combustion and oxides of nitrogen.
