摘要： An exhaust gas purification catalyst includes: a lower catalyst layer that contains a ceria-zirconia mixed oxide having 50 to 70 mass % of CeO2 and 5 mass % or more of Pr2O3 and carries at least one of Pt and Pd; and an upper catalyst layer that contains at least zirconia and carries at least Rh, wherein the total amount of CeO2 per liter of the carrier base is 15 to 30 g. Because the amount of CeO2 is small, formation of H2S is suppressed and a high capability of adsorbing and releasing oxygen is brought out in spite of the small amount of CeO2.
摘要翻译：废气净化催化剂包括：含有氧化铈 - 氧化锆混合氧化物的下部催化剂层，其具有50〜70质量％的CeO 2和5质量％以上的Pr 2 O 3，并携带Pt和Pd中的至少一种; 和至少含有氧化锆并至少含有Rh的上部催化剂层，其中每升载体碱的CeO 2的总量为15〜30g。由于CeO 2的量少，因此抑制了H 2 S的形成，并且尽管CeO 2的量少，但是吸附和释放氧的能力也很高。

摘要： The fact that “with respect to a process in which the output value of a downstream air-fuel ratio sensor (sensor output value) is inverted from the minimum output value to the maximum output value during execution of an active control, the local maximum and minimum values of the secondary differential value of the sensor output value is widely affected by the size of the response delay of the downstream air-fuel ratio sensor and the size of the degree of the degradation of the three-way catalyst” is utilized. By preliminarily acquiring and memorizing, as maps, these relations obtained through an experiment, and applying the “local maximum and minimum values of the secondary differential value of the sensor output value” calculated from the transition of the sensor output value acquired during execution of the active control to the maps, the response delay (time constant) of the downstream air-fuel ratio sensor is acquired.
