Abstract
An exhaust emission control system of an internal combustion engine may include a filter, a temperature raising device, a differential pressure detecting device, and an electronic control unit. The filter may include a first region as a part of the filter, and a second region as another part of the filter. The electronic control unit may be 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 may be 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.
