ABSTRACT:
An exhaust purification system for use with diesel or other compression ignited systems to remove particulate and gaseous pollutants from the exhaust. The system includes a catalytic converter assembly that heats the exhaust to a level sufficient to incinerate particulate pollutants in the exhaust prior to the pollutants contacting the catalytic element and a plurality of gas cooling elements communicating with the exhaust outlet in the catalytic converter assembly for reducing the temperature of the exhaust passing from that assembly to about 100° F. whereupon the cooled exhaust is directed back to the engine for further combustion.
