  "textContent": "A filter is disposed on an exhaust path of the internal combustion engine to capture particulate matter exhausted from the internal combustion engine. A controller is caused to execute regeneration control that incinerates the particulate matter captured on the filter. The controller accomplishes the regeneration control by executing lean incineration control and stoichiometric incineration control in combination with each other. The lean incineration control incinerates the particulate matter, keeping an air-fuel ratio of the internal combustion engine to be leaner than a logical air-fuel ratio. The stoichiometric incineration control incinerates the particulate matter, oscillating the air-fuel ratio of the internal combustion engine about the logical air-fuel ratio as an average air-fuel ratio at a predetermined first cycle.",
