摘要： PROBLEM TO BE SOLVED: To provide a NOx removing device which can make an exhaust gas temperature adequate to carry out a NOx reduction, and has a high energy efficiency. SOLUTION: The device comprises an exhaust gas flow path provided with an intake air conduit 10 and an exhaust air conduit 11, a heat conductor 1 comparting the betweenness of the intake air conduit 10 and the exhaust air conduit 11, and carrying out a heat exchange between them, and an oxidation-reduction catalyst containing a NOx reduction catalyst, provided in the exhaust gas flow path. That is, the oxidation-reduction catalyst is arranged in the exhaust gas flow path, and the heat exchange between the exhaust gas warmed by the produced heat and the exhaust gas before reaching the NOx reduction catalyst can minimize successfully a new charge of heat (energy) from outside. Since the heat exchange can control the exhaust gas temperature with the minimum energy charge from outside, it is possible to suppress a vain energy charge, which is useful for both ways of an improvement in fuel consumption and an emission gas purification.

摘要： PROBLEM TO BE SOLVED: To improve particle matter cohesion performance of an exhaust gas treating device using corona discharge. SOLUTION: In this exhaust gas treating device, by arranging two types of electrodes, a discharge electrode 2 and a dust collecting electrode 4, inside an exhaust pipe of the internal combustion engine and applying high voltage to a space between the electrodes 2, 4 to generate corona discharge, exhaust particles in the exhaust gas are charged and collected. Negative charges carried by the collected exhaust particles are recovered via a coil 5. Since an electric current is suppressed by the action of the coil 5, the exhaust particles in the side opposite to the dust collecting electrode 4 are positively charged. Due to Coulomb force by such charges, cohesion of exhaust particles which have not reached the dust collecting electrode 4 and are negatively charged is promoted. COPYRIGHT: (C)2006,JPO&NCIPI
