    摘要: The device for cleaning exhaust gas of the internal combustion engine includes means provided in an exhaust gas passage (15) of the internal combustion engine (10), such as a NOx catalyst (20), a SOx trap catalyst (30) provided at a position upstream from the exhaust gas cleaning means, and means (40, 41) for feeding ozone to a position upstream from the SOx trap catalyst. SOx in the exhaust gas is absorbed by the SOx trap catalyst before reaching the NOx catalyst. Particularly, it is possible to oxidize SOx in the exhaust gas by ozone as oxidizing gas to be an easily decomposable state, whereby SOx is absorbable even at a low temperature. Preferably, the SOx trap catalyst has no active points consisting of precious metal. In such a case, the SOx trap catalyst is prevented from being sulfur-poisoned whereby the deterioration of the SOx absorbing ability is avoidable.

    摘要: An exhaust gas purifying apparatus provided in an exhaust passage connected with an engine includes an upstream catalyst that is provided in the exhaust passage, and that removes NOx; a downstream catalyst that is provided downstream of the upstream catalyst in the exhaust passage; and a supply device that supplies an oxygen-activating component to a portion of the exhaust passage located between the upstream catalyst and the downstream catalyst. In the exhaust gas purifying apparatus, the upstream catalyst removes NOx, and then an oxygen-activating component is supplied to the exhaust gas. Further, the downstream catalyst removes a hydrocarbon compound contained in the exhaust gas.

    摘要: A device for controlling an internal combustion engine comprises a device for trapping particulate matter (PM) in exhaust gas in an exhaust passage, means for supplying ozone to the particulate matter trapping device from the upstream thereof to oxidize and remove PM deposited in the device, and means for interrupting the fuel injection of the internal combustion engine upon the execution of ozone supply by the ozone supply means. It is possible to prevent components consuming ozone, such as NOx, from being contained in the exhaust gas of the internal combustion engine, whereby ozone is effectively usable.
