    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.

    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
