EXHAUST CONTROLLING APPARATUS FOR INTERNAL COMBUSTION ENGINE

A filter (4) is disposed on an exhaust path (2) of the internal combustion engine (1) to capture particulate matter exhausted from the internal combustion engine (1). A controller (10) is caused to execute regeneration control that incinerates the particulate matter captured on the filter (4). The c...

Beschreibung
Zusammenfassung:	A filter (4) is disposed on an exhaust path (2) of the internal combustion engine (1) to capture particulate matter exhausted from the internal combustion engine (1). A controller (10) is caused to execute regeneration control that incinerates the particulate matter captured on the filter (4). The controller (10) 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 (1) 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 (1) about the logical air-fuel ratio as an average air-fuel ratio at a predetermined first cycle.
