摘要： A plurality of catalysts (7), (9) are disposed in an engine exhaust passage (13). At least the catalyst disposed downstream of these catalysts comprises a multi-layered catalyst (7) which is covered in a catalyst layer (24a) on the surface and an HC absorbent layer (24b) on an inner layer with respect to a catalyst carrier (23). A ratio of the downstream multi-layered catalyst (7) (catalyst heat capacity/catalyst surface area) is set so that it is greater than the same ratio for the upstream catalyst (9). In this way, temperature increase in the upstream catalyst (9) is advanced, the temperature gradient in the downstream catalyst (7) is increased and temperature rises in the HC absorbent layer are reduced. As a result, the HC emission period approximates the activation period of the catalyst layer (24a). In this way, during low temperature vehicle operation, it is possible to synchronize the timing of HC emission by the HC absorbent layer and catalyst activation and therefore to achieve extreme reductions in HC emitted to the outside atmosphere.
摘要翻译：多个催化剂（7），（9）设置在发动机排气通道（13）中。至少设置在这些催化剂下游的催化剂包括覆盖在表面上的催化剂层（24a）中的多层催化剂（7）和相对于催化剂载体的内层上的HC吸收层（24b） 23）。下游多层催化剂（7）（催化剂热容量/催化剂表面积）的比例被设定为大于上游催化剂（9）的相同比例。这样，上游催化剂（9）的温度上升，下游催化剂（7）的温度梯度上升，HC吸收层的温度上升降低。结果，HC排放周期近似于催化剂层（24a）的活化时间。以这种方式，在低温车辆操作期间，可以使HC吸收层的HC排放的定时和催化剂的活化同步，从而实现对外部气氛的HC的极度降低。
