An exhaust gas purifying catalyst which is disposed in an exhaust pipe of an internal combustion engine, includes: a substrate; and a catalyst layer, supported in the substrate and including: noble metals including platinum (Pt) and palladium (Pd); a heat-resistant inorganic oxide; and a NOx trapping material. The exhaust gas purifying catalyst adsorbs NOx in an exhaust gase when an exhaust air-fuel ratio is in a lean state and desorbs and reduces the adsorbed NOx when the exhaust air-fuel ratio is in a stoichiometric state or a rich state. (Pt/Pd) which is a ratio of amount of the platinum (Pt) to amount of the palladium (Pd) is 0.7 or more and less than 1.0.

摘要:
An exhaust manifold maintains the EGR ratio constant irrespective of a change in shape of the exhaust manifold and includes exhaust gas inlet sections connected to the exhaust ports of respective cylinders of the engine; a main pipe section configured so that exhaust gas entering from the exhaust gas inlet sections is collected inside the main pipe section; an EGR gas taking-out section for extracting, as EGR gas, a part of the exhaust gas; and an exhaust gas discharge section for discharging the exhaust gas. The main pipe section has formed thereon a curved section provided between the exhaust gas inlet sections and curved in a shape protruding to the side opposite the exhaust gas inlet sections. The curved section has a recess which is formed by causing a portion of the outer peripheral surface of the curved section to be recessed toward the inside of the main pipe section.
摘要:
A sheet feeding device for a printer, e.g., a stencil printer including an ink drum with a master wrapped therearound and a press drum one of which is pressed against the other during printing is disclosed. The sheet feeding device is capable of feeding a sheet at a preselected speed without regard to a print speed varying every moment due to various factors particular to an ink drum driveline, i.e., whether a set print speed is higher than a standard print speed or lower than the same. This successfully obviates the short loop of a sheet which would result in a skew or a feed failure. In addition, the device reduces noise at print speeds lower than the standard print speed and used more often than the other print speeds.
