    摘要: An exhaust gas purifying catalyst for use in an oxygen surplus atmosphere, includes a brown millerite composite oxide for directly decomposing and absorbing nitrogen oxide (NOx), and a noble metal-series reducing catalyst disposed on the surface of said brown millerite composite oxide. The brown millerite composite oxide is represented by one of the following formulae: A3-aBaC4-bDbO9, A2-aBaC2-bDbO5, and A1-aBaC2-bDbO4 where A and B are elements selected from the group consisting of Ba, Ca, Sr, Mg and Ce, C and D are elements selected from the group consisting of Y, Dy, Zn, Ti, Mn, Fe, Co, Ni, Cu, Sn, Zr and Nd, a is within the range 0≦a

    摘要: An exhaust gas purifying apparatus provides a reflux pipe for connecting an intake pipe to an exhaust pipe and an EGR valve disposed in the reflux pipe for adjusting a flow rate of the exhaust gas flowing through the reflux pipe. A nitrogen oxide purifying catalyst section is formed by a brown miralite type composite oxide. A pair of electrodes are provided on the vicinity of the opposite ends of the purifying catalyst section. A conductivity measuring section measures conductivity of a nitrogen oxide catalyst of the nitrogen oxide purifying catalyst section through the electrodes. A control section controls an opening degree of the EGR valve on the basis of engine rpm, engine load and the conductivity measured in the conductivity measuring section.
