    摘要： An exhaust emission control system of an internal combustion engine includes a filter (4), a temperature raising device (3), a differential pressure detecting device (8), and an electronic control unit (20). The filter (4) includes a first region as a part of the filter (4), and a second region as another part of the filter (4). The electronic control unit (20) is configured to calculate a first deposition amount such that a calculated deposition amount is larger as a proportion of a magnitude of the first differential pressure reduction amount to the length of the first oxidation period is larger. The electronic control unit (20) is configured to calculate an amount of the particulate matter deposited in the second region based on a length of the second oxidation period and a second differential pressure reduction amount.

    摘要： An object of the present invention is to distinguish and detect an abnormality of SCRF and an abnormality of a diffusing device in a system in which a diffusing device is provided for an exhaust gas passage between a filter (SCRF) including an SCR catalyst carried thereon and a reducing agent addition valve. In the present invention, it is judged that which one of abnormalities of any clogging-up of SCRF caused by PM, any breakage of SCRF, and any abnormality of a diffusing device occurs, on the basis of at least any one of a difference between a NOx purification rate of an SCR catalyst carried on SCRF and a predetermined NOx purification rate and a difference between a PM amount flowing out from SCRF and a predetermined outflow PM amount, when a difference, which is provided between an exhaust gas pressure difference as a difference between an exhaust gas pressure on an upstream side from a reducing agent addition valve and an exhaust gas pressure on a downstream side from SCRF and a predetermined exhaust gas pressure difference, exceeds a certain amount.

    摘要： An abnormality determination apparatus of a particulate filter (DPF 54) according to an embodiment of the present invention supplies a fuel to a catalytic device (DOC 53) by an unburnt components supply section (an adding fuel valve 35 and an added fuel providing pipe 34) when a specific condition is satisfied, so as to raise a temperature of the catalytic device. Accordingly, a volumetric flow rate of a gas which passes through the DPF increases. Further, the abnormality determination apparatus acquires a differential pressure ΔP using a differential pressure acquisition section (differential pressure sensor 77) in a state where the temperature of the catalytic device is raised, and determines whether an abnormality occurs in the DPF 54 on the basis of a comparison result between a correlation value (a final determination value B) correlated with the acquired differential pressure and a predetermined value (a final determination threshold value Sbth).
