    摘要: An exhaust purification device of an engine providing a NO x absorbent arranged in the exhaust passage. An O 2 sensor generating a current proportional to the air-fuel ratio is arranged in the engine exhaust passage downstream of the NO x absorbent. The amount of NO x actually absorbed in the NO x absorbent at the time of release of the NO x is calculated on the basis of the output signal of this O 2 sensor. On the basis of this calculated amount of NO x , correction is made so that the estimated amount of NO x represents the actual amount of absorption of NO x . When this corrected estimated amount of NO x reaches a set value, the action of releasing the NO x from the NO x absorbent is carried out.

    摘要: To provide a particulate matter purifying device which is capable of providing excessive deposition pf particulate matter.
    In the particulate matter purifying device, a catalyst element 11 is carried on a porous filter substrate 10 through which an exhaust gas passes. The particulate matter purifying device traps particulate matter contained in the exhaust gas, and oxidizing the trapped particulate matter to remove. This particulate matter purifying device is characterized in that active oxygen producing fine particles 12 are carried on a surface of the filter substrate 10 between the catalyst elements 11. Therefore, the particulate matter is partially damaged by the active oxygen produced by the active oxygen producing fine particles 12. Consequently, oxidization of the particulate matter is promoted so that deposition of the particulate matter is prevented or minimized.
