摘要： A hydrogen storing alloy comprising a body-centered cubic lattice structure having a composition of MgX a V b wherein "a" and "b" are such that 0.2≦a≦5 and 0.2≦b≦5 are satisfied, and "X" is one or more metals selected from a group consisting of Cr, Mn, Fe, Co, Cu and Ni. Since the body-centered cubic lattice structure is under the non-equilibrium state in which the bonding strength between the stored hydrogen and the alloy is relatively weak, the hydrogen absorption and release at the ordinary temperature level are possible. The conventional magnesium-based hydrogen storing alloy is sufficient in its higher hydrogen storing amount and lightness. However, the conventional alloy could not absorb and release at the ordinary temperature level, thereby inhibiting the commercial availability. The present invention can provide the magnesium-based hydrogen storing alloy which can absorb and release the hydrogen at the ordinary temperature level.
摘要翻译：一种储氢合金，其特征在于，含有具有MgXaVb的组成的体心立方晶格结构，其中a和b满足0.2≤a≤5,0.2≤b≤5，X为1个以上选自Cr，Mn，Fe，Co，Cu和Ni的金属。由于体心立方晶格结构处于储存的氢与合金之间的结合强度相对较弱的非平衡状态，因此可以在常温水平下进行氢吸收和释放。常规的镁基储氢合金在其较高的储氢量和轻量方面是足够的。然而，常规合金在常温下不能吸收和释放，从而抑制了商业可用性。本发明可以提供能够在常温下吸收和释放氢的镁基储氢合金。

摘要： An object of the present invention is to suppress HC, CO, and NOx from being discharged to the outside when a filter regeneration process is executed in an exhaust gas purification system for an internal combustion engine provided with a filter including an SCR catalyst carried thereon. In the present invention, a post-catalyst is provided for an exhaust gas passage disposed on a downstream side from the filter. The post-catalyst has an oxidizing function, and the post-catalyst has such a function that the production of N 2 based on the oxidation of ammonia is facilitated in a predetermined first temperature area. Further, when the filter regeneration process is executed, the temperature of the post-catalyst is adjusted to be in the first temperature area while adjusting the temperature of the filter to be in a predetermined second temperature area lower than a filter regeneration temperature during a certain period of time.

摘要： A control apparatus for an internal combustion engine having an exhaust gas purification device which is arranged in an exhaust passage and includes a NO x storage reduction (NSR) catalyst. The control apparatus, when the air fuel ratio of the air-fuel mixture is shifted from a lean air fuel ratio to the stoichiometric air fuel ratio, determines a predetermined NO x amount so as to be larger when the temperature detected by the first detection unit is high in comparison with when the detected temperature is low, and when the storage amount of NO x in the NSR catalyst is larger than the predetermined NO x amount, performs the rich spike processing and then controls the air fuel ratio to the stoichiometric air fuel ratio, whereas when otherwise, controls the air fuel ratio to the stoichiometric air fuel ratio without performing the rich spike processing.

摘要： To estimate an amount of reducing agent adsorbed to a selective reduction type NOx catalyst with a higher degree of precision, an amount of variation over a predetermined time in a reducing agent amount adsorbed to a selective reduction type NOx catalyst is calculated from an upper limit value of a reducing agent amount that is adsorbed to the selective reduction type NOx catalyst when the reducing agent is supplied continuously by a supply unit, which is calculated on the basis of a temperature of the selective reduction type NOx catalyst, and the reducing agent amount adsorbed to the selective reduction type NOx catalyst, whereupon a reducing agent amount adsorbed to the selective reduction type NOx catalyst following the elapse of the predetermined time is estimated by adding the variation amount to the reducing agent amount adsorbed to the selective reduction type NOx catalyst.

摘要： In an exhaust gas recirculation system for an internal combustion engine, which includes a turbocharger; a high-pressure EGR unit; a low-pressure EGR unit; a high-pressure EGR valve; and a low-pressure EGR valve, first, the opening amount of the high-pressure EGR valve is controlled in a feedback manner, and, then, the opening amount of a low-pressure EGR valve is controlled in a feedback manner in a transitional operation period in which the operation mode of the internal combustion engine is changing. In this way, the intake air amount is promptly adjusted to the target intake air amount without causing hunting.
