Abstract
An emission control device for an internal combustion engine is configured to perform a particulate matter trap function of trapping, with a particulate filter, particulate matter contained in exhaust gas which flows in an exhaust passage of the internal combustion engine. The emission control device includes a controller. The controller is configured to calculate a particulate matter accumulation amount, which is a total amount of particulate matter trapped by the particulate filter based on an operation condition of the internal combustion engine. The controller is configured to stop calculating the particulate matter accumulation amount when the particulate matter trap function is not functioning.
