  • Publication number: 20190285210
    Abstract: In a flange fastening structure, a turbocharger includes a wastegate decentered from a center of a first flange that surrounds an outlet opening of the turbocharger. A bolt of a V-band that fastens the first flange on the turbocharger to a second flange on an exhaust passage member is disposed in a first region. The first region is a region composed of two sector-shaped regions each having a central angle of 90 degrees from a straight line from the center through a point that is on the first flange and that is closest to a maximum opening portion of the wastegate toward a corresponding side in a circumferential direction.

  • Patent number: 9970342
    Abstract: An exhaust gas purification device is equipped with: an NOx purification unit disposed in exhaust gas piping of an engine supporting an NOx storage catalyst (NSC); a catalyzed soot filter (CSF) disposed downstream of the NOx purification unit supporting a particulate combustion catalyst causing captured particulates to combust; and an electronic control unit (ECU) which controls exhaust gas flowing into the NSC to be rich and which, by raising the temperature of the NSC, acts as a regeneration device that causes sulfur components captured in the NSC to be desorbed. The particulate combustion catalyst is provided where Ag and Pd have been alloyed on an Al2O3 carrier; the quantity of Ag supported by the Al2O3 carrier is 1.2-2.5 g/L; the quantity of Pd supported by the Al2O3 carrier is 0.7 g/L or less; and the ratio Ag/Pd of the Ag support quantity to the Pd support quantity is 1.7-8.3.
