Beschreibung
Zusammenfassung:	An exhaust gas control apparatus for an internal combustion engine includes an electromagnetic wave output unit, an acquisition unit that acquires collection amounts of PM and substances other than PM based on a rotational speed and a fuel injection amount of the internal combustion engine, and a control unit that controls an output intensity of the electromagnetic wave output unit. The control unit causes electromagnetic waves to be output with a first output intensity when the collection amount of the substances other than PM becomes equal to or smaller than a predetermined threshold, and causes electromagnetic waves to be output with a second output intensity that is lower than the first output intensity when the collection amount of the substances other than PM becomes larger than the predetermined threshold, when the collection amount of PM has exceeded a permissible value of the collection amount of PM in the filter.
