EXHAUST GAS POST-TREATMENT SYSTEM FOR DIESEL ENGINE

摘要

PURPOSE: An exhaust gas post-treatment system is provided to reduce particulate pollutant and power consumption, while shortening length of the plasma reaction space. CONSTITUTION: An exhaust gas post-treatment system comprises a case(1) having an inlet(2) for introduction of exhaust gas and an outlet(3) for discharge of exhaust gas; a ceramic filter(4) serving as a dielectric, which forms a plasma reaction space(20) in the case so as to allow for passage of exhaust gas; an electrode(10) accommodated in the ceramic filter so that the electrode is not directly exposed to exhaust gas and generates high voltage; and a plug(30) for closing the exit of the plasma reaction space so that the particulate is collected in the plug while only the gaseous material from among the introduced exhaust gas is passing through the plug.
