Abstract: A particulate filter (23) for trapping the particulate matter which is contained in the exhaust gas is provided inside an engine exhaust passage. Additional fuel is secondarily injected from a fuel injector (3) in an engine expansion stroke or exhaust stroke or hydrocarbons are secondarily added from an addition valve (24) which is provided upstream of the particulate filter in the exhaust pipe (21). An amount of hydrocarbons which come from the fuel injector (3) or addition valve (24) and then adhere in the form of a liquid to the inflow end of the particulate filter, and an amount of particulate matter which reaches the inflow end of the particulate filter are respectively estimated. A degree of clogging at the inflow end of the particulate filter is estimated based on the amount of hydrocarbons and the amount of particulate matter.

Abstract: A fuel addition valve (14) that adds fuel into the exhaust gas passage of the engine in the form of fine fuel droplets, an upstream NOx adsorption-reduction catalyst (12), and a downstream NOx adsorption-reduction catalyst (13) are arranged in this order. Platinum Pt and palladium Pd, as noble metal, are supported on the downstream NOx adsorption-reduction NOx catalyst (13) such that the ratio of the mole number of the platinum Pt to the sum of the mole numbers of the platinum Pt and the palladium Pd is approx. 50% to approx. 80%. Only platinum Pt is supported on the upstream NOx adsorption-reduction catalyst (12). According to this structure, even when liquid fuel is supplied into exhaust gas, NOx can be effectively released from the NOx adsorption-reduction catalyst, and further the amount of NOx that the NOx adsorption-reduction catalyst can adsorb at a low temperature increases.

Abstract: An exhaust gas purification device includes an SOx trap catalyst that is disposed in an exhaust passage upstream of an NOx occlusion/reduction catalyst and that suppress occlusion of SOx by the NOx occlusion/reduction catalyst. The exhaust gas purification device further includes a selective reduction catalyst that selectively reduces NOx using ammonia, disposed downstream of the NOx occlusion/reduction catalyst, and a control unit. When an air-fuel ratio of the exhaust gas flowing into the SOx trap catalyst is lean, the control unit executes a exhaust gas purification control to temporarily make an air-fuel ratio of the exhaust gas flowing into the NOx occlusion/reduction catalyst rich to reduce NOx occluded by the NOx occlusion/reduction catalyst and generate ammonia, whereby the ammonia produced as a result of the exhaust gas purification control is used by the selective reduction catalyst to reduce NOx.
