    摘要: An exhaust gas purifying catalyst for oxidizing HC and CO and for reducing NOx is provided, which comprises at least one oxide of rare earth element, rhodium, and at least one of platinum and palladium loaded on alumina grains. The major amount of rhodium is dispersed on the oxide of rare earth element. Thus, the rhodium solidification into the alumina grains is prevented. Further, when cerium oxide accompanying lanthanum oxide, neodymium oxide or a mixture thereof is used as the oxide of rare earth element, the sintering of cerium oxide or palladium at a high temperature is suppressed since it forms a complex oxide with lanthanum oxide, neodymium oxide or a mixture thereof. Additionally, when stabilized alumina grains in which a rare earth element and an alkali earth element are present in a solid solution state are used, the deterioration of NOx purifying activity of the catalyst at a high temperature is suppressed. The exhaust gas purifying catalyst of this invention has high durability as well as high activity at a high temperature.

    摘要: The invention relates to an acceleration slip control device, wherein the control quantity for the throttle valve angle operation is determined not only in response to the slip condition but also to the output torque changeability of the internal combustion engine with regard to the throttle valve angle displacement, therefore the output torque of the engine can be effectively restrained to the optimum value counteractive to the slip condition of the driving wheels.
