The research status of the world diesel exhaust aftertreatment technology is summarized systemicallyo at the same time, the development status and problems about oxygenation catalysis converter and particulate filter are analyzed on the basis of mentioned informations, we bring up a diesel exhaust cleanse system, that adopts the technique course of catalysis conversion combining particulate collection and regeneration the system collects exhaust particulate by means of efficacious filtering material it can oxidize ho co and macromolecule solvable organic via catalyst and diesel oil additive enhanced temperature will partly oxidize collected particulate and ultimately achieve the aim of exhaust reduction, after processing system frame design and trial matching, it ' s detected that the system can surely cleanse gas exhaust and particulate in addition, gas - ejected combustion - supporting regeneration for diesel particulate filter is also researched, we have rudimentarily designed the software and hardware of the g as - ejected combustion - supporting system having processed a series of trials, we discover the rules of the system credibly working these rules demonstrate the right direction for researching gas - ejected combustion - supporting regeneration technology
