摘要： In a three-way catalyst for purifying exhaust gases from internal combustion engines, scattering of bismuth components can be suppressed by employing a Bi-Ti composite oxide at a predetermined ratio. Accordingly, the effect of suppressing hydrogen sulfide emissions can be retained for a long time. This catalyst comprises a support substrate, and a catalyst layer formed on the support substrate and including a noble metal, a porous oxide, and a Bi-Ti composite oxide, and satisfies 0.3 R 1.5, where R is the molar ratio of the Bi content to the Ti content per unit volume of the support substrate.

摘要： A catalyst for purifying an exhaust gas comprising a support including rutile type titania, an NO x storage material including at least one element selected from the group consisting of alkali metals, alkaline-earth metals and rare-earth elements and loaded on the support, and a noble metal loaded on the support.
Since the rutile type TiO 2 and the NO x storage material form a fine composite oxide, the NO x storage material is likely to decompose even when it is subject to the sulfur poisoning, and the NO x storage material easily recovers the NO x storage ability. Therefore, the NO x storage material can be inhibited from the sulfur poisoning, and a high NO x conversion ratio can be maintained even after the service at an elevated temperature.摘要翻译： 一种用于净化废气的催化剂，包括包含金红石型二氧化钛的载体，包含选自碱金属，碱土金属和稀土元素中的至少一种元素并装载在载体上的NO x储存材料，以及 一种装载在支架上的贵金属。 由于金红石型TiO 2和NO x保存材料形成微细的复合氧化物，所以即使经受硫中毒，NO x储存材料也易分解，并且NO x储存材料容易恢复NO x储存能力。 因此，可以抑制NO x保存材料的硫中毒，即使在高温下使用后也能够维持高NO x转换比。

摘要： A fuel tank apparatus includes a sub-cup (21) having a bottom portion (22) and a side portion (23) erected from said bottom portion (22) and provided in a fuel tank (12) and a suction filter (31) arranged in a space surrounded by the side portion (23) above the bottom portion (22) and connected to a fuel pump (41). The side portion (23) includes a partition wall (23n) partitioning the space into a main chamber (28) in which the suction filter (31) is arranged, and a sub-chamber (29). Maximum height H1 of the suction filter (31) is higher than the height H2 of the partition wall (23n). Because of such a structure, a fuel tank apparatus can be provided by which the fuel can reliably be supplied even when much water is retained in the tank.
