Abstract: The exhaust gas post-processing device includes: an exhaust gas post-processing unit into which an exhaust gas is introduced; a drain pipe connected to a lower portion of the exhaust gas post-processing unit; and a junction member. The junction member includes an introduction flow path, one end of which is an introduction port connected to the drain pipe, the introduction flow path extending in a horizontal direction from the introduction port, and the other end of the introduction flow path being an introduction-side gas vent hole opened to an outside. A discharge flow path is connected to a lower portion of the introduction flow path, that extends, in the horizontal direction, in a direction intersecting the introduction flow path, and an end portion of the discharge flow path being a discharge port opened to the outside. The exhaust gas post-processing device further includes a drainage pipe connected to the discharge port.

Abstract: An EGR apparatus configured to circulate exhaust gas discharged from an exhaust manifold of an engine to an intake manifold of the engine includes: an EGR cooler disposed at a downstream side of the exhaust manifold and configured to cool the exhaust gas discharged from the exhaust manifold; a pair of EGR valves disposed at an upstream side from the intake manifold and configured to adjust an amount of the exhaust gas to be supplied to the intake manifold; and an exhaust gas connector that establishes communication between the EGR cooler and the exhaust manifold, in which the exhaust gas connector includes a cooling water path to which cooling water for cooling the exhaust gas flowing inside the exhaust gas connector is supplied.

Abstract: A color prediction system includes: database storing absorption/scattering coefficients of each primary color ink; sections for: selecting a spot color ink as a combination of primary color inks that reproduce a colorimetric value of a color sample, reading absorption and scattering coefficients of the primary color inks of a reference spot color from the database, obtaining absorption and scattering coefficients of the spot color ink of a specified formulation ratio, and calculating a spectral reflectance of the spot color ink to be reproduced; obtaining a reproduced color from the spectral reflectance; obtaining a difference from the colorimetric value of the color sample and correcting the formulation ratio to calculate a formulation ratio with an allowable difference; and calculating a Neugebauer primary color of overprinted spot color inks from the absorption and scattering coefficients of the spot color inks calculated at formulation ratios determined by the formulation ratio determination section.
