<p><P>PROBLEM TO BE SOLVED: To realize a cohesive device capable of holding insulation with a simple constitution, without causing electric current leakage by a deposit of an exhaust particulate to an insulator part even in the presence of the exhaust particulate of the high concentration, in an exhaust processing system of an internal combustion engine using corona discharge. <P>SOLUTION: A corona discharge electrode 2 and a conductive net 3 being a dust collecting electrode are oppositely arranged in an exhaust passage 11 of the cohesive device 1. The corona discharge electrode 2 has a discharge part 22 positioned in a substantially central part of the exhaust passage 11, a conductive part 21 introducing high voltage from an external power source to the discharge part 22, and the insulator part 23 holding the outer periphery of the conductive part 21. A Pt carrying part projecting in a ring shape is arranged on the outer periphery of the insulator part 23, and the insulation is held by removing the sticking exhaust particulate by the catalytic action of Pt included on at least its outside surface. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
