Diesel engine exhaust purification system

摘要

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.
