摘要： A metal oxide catalyst carrier particle has a center portion and an outer skin portion each containing a first metal oxide and a second metal oxide. The center portion and the outer skin portion are different in composition. The mole fraction of the metal of the first metal oxide is higher in the center portion than in the outer skin portion and the mole fraction of the metal of the second metal oxide is higher in the outer skin portion than in the center portion. The second metal oxide is selected from the group consisting of rare earth oxides, except for ceria, and alkali earth metal oxides. In addition, platinum is supported on the metal oxide catalyst carrier particle, thus forming an exhaust gas purification catalyst.

摘要： An apparatus is for purifying an exhaust gas flowing from an internal combustion engine equipped with a turbocharger (2), and includes an injector (12), a vaporization enhancer (5), and an NO x sorbing-and-reducing catalyst (4). The injector (12) injects a liquid reducing agent into the exhaust gas, and is disposed on an upstream side of the turbocharger (2). The vaporization enhancer (5) is disposed between the injector (12) and the turbocharger (2). The NO x sorbing-and-reducing catalyst (4) is disposed on a downstream side of the turbocharger (2). The vaporization enhancer (5) enhances a vaporization of the liquid reducing agent. Accordingly, the liquid reducing agent hardly adheres onto the inlet-end of the NO x sorbing-and-reducing catalyst (4). Consequently, PMs scarcely adhere onto the liquid reducing catalyst. Therefore, the exhaust pressure loss is inhibited from increasing, and the NO x purifying performance upgrades.
摘要翻译：一种用于净化从配备有涡轮增压器（2）的内燃机流出的废气的装置，包括喷射器（12），汽化增强器（5）和NOx吸附 - 还原催化剂（4）。注射器（12）将液体还原剂注入废气中，并且设置在涡轮增压器（2）的上游侧。蒸发增强剂（5）设置在喷射器（12）和涡轮增压器（2）之间。 NOx吸附还原催化剂（4）设置在涡轮增压器（2）的下游侧。汽化增强剂（5）增强了液体还原剂的蒸发。因此，液体还原剂几乎不附着在NOx吸附还原催化剂（4）的入口端。因此，PMs几乎不附着在液体还原催化剂上。因此，能够抑制排气压力损失的增加，从而提高NOx净化性能。

摘要： An exhaust gas control apparatus includes an exhaust gas purification catalyst and a controller. The controller is configured to alternately change a concentration of hydrocarbon flowing in the exhaust gas purification catalyst between a high concentration region where the concentration of hydrocarbon is relatively high and a low concentration region where the concentration of hydrocarbon is relatively low in a predetermined period. The exhaust gas purification catalyst includes a support (75), metal catalysts (70, 72) supported on the support (75), and a NOx storage material (74) supported by the support (75) and having NOx storage capacity. The NOx storage material (74) contains a barium-titanium composite oxide where barium (74a) and titanium (74b) are dissolved to form a solid solution.
