摘要： An electrically heating catalytic apparatus that quickly heats catalyst to an activation temperature even when the engine is started at a low temperature below the catalyst activation temperature. The apparatus employs an electrically conductive catalyst carrier that is electrically heated. The carrier is provided with local hot spots to be energized. Since the heat is locally generated, the heat capacity of the catalyst carrier is small to shorten a temperature increasing time.
摘要翻译：即使在低于催化剂活化温度的低温启动发动机时也能迅速将催化剂加热至活化温度的电加热催化装置。该装置采用电加热的导电催化剂载体。载体上设有通电的局部热点。由于局部产生热量，所以催化剂载体的热容量小，以缩短升温时间。

摘要： An electrically heated catalytic converter having a scroll-like cylindrical laminated assembly in which belts of thin corrugated metal sheet and a thin plain metal sheet are laminated and wound around a center electrode, and the outermost layers are connected to an outer electrode. The corrugated metal sheet has an insulating coating made of a metal oxide, and the plain metal sheet has no insulating coatings. Conductive connections in which the corrugated metal sheet and the plain metal sheet are electrically connected to each other through the insulating coating of the corrugated metal sheet are made at predetermined positions in the layers of the laminated assembly and electric paths of desired shapes are formed by these conductive connections. The corrugated metal sheet and the plain metal sheet are connected in the areas around the respective conductive connections in such a manner that the metal sheets are isolated from each other. Thus, the cross sectional area of the respective conductive connections can be reduced without reducing the total connection area between the metal sheets. Since the cross sectional area of the respective connections can be reduced, the intensity of the electric current is increased in the conductive connections. Therefore, the conductive connections are heated rapidly by electric current and reach the activating temperature of the catalyst carried by the metal sheets.
摘要翻译：一种电加热催化转化器，其具有涡卷状圆柱形层压组件，其中薄波纹金属板和薄平板金属板的带层压并卷绕在中心电极上，最外层连接到外电极。波纹金属片具有由金属氧化物制成的绝缘涂层，并且该普通金属片没有绝缘涂层。通过波纹状金属片的绝缘层将波纹状金属片和普通金属片彼此电连接的导电连接在层压组件的层中的预定位置处形成，并且通过这些形成所需形状的电路径导电连接。波纹状金属片和普通金属片以金属片彼此隔离的方式连接在各导电连接件周围的区域中。因此，可以在不减少金属片之间的总连接面积的情况下减小各个导电连接的横截面面积。由于可以减小各个连接的横截面积，所以导电连接中的电流强度增加。因此，导电连接被电流迅速加热并达到由金属片承载的催化剂的活化温度。

摘要： An engine comprising an exhaust passage having therein a NO.sub.x absorbent which absorbs the NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent is lean and releases the absorbed NO.sub.x when the concentration of oxygen in the exhaust gas is lowered. When the air-fuel ratio of air-fuel mixture fed into the engine cylinder is made a rich air-fuel ratio or the stoichiometric air-fuel ratio, a secondary air is fed into the exhaust passage upstream of the NO.sub.x absorbent to make the air-fuel ratio of exhaust gas lean.

摘要： A catalyst for purifying exhaust gases comprises a catalyst carrier made of potassium titanate and a noble metal loaded on the catalyst carrier. The catalyst carrier is substantially free from alumina. This catalyst can oxidize at least hydrocarbons in exhaust gases at a high catalytic activity even at low temperatures, and at the same time can suppress SO.sub.2 from converting into sulfates. This catalyst does not employ substance like alumina exhibiting solid acidity as a catalyst carrier. Further, this catalyst can be used for purifying exhaust gases from diesel engines to suppress particulates and sulfates from being emitted, and to improve conversions of hydrocarbons and carbon monoxide.
