Abstract
The present invention provides an internal combustion engine exhaust purification apparatus includes a filter configured to collect particulate matter contained in exhaust gas, a selective catalytic reduction converter provided downstream of the filter to reduce nitrogen oxide contained, an oxidation catalyst converter with an adsorption function provided upstream of the converter to temporarily adsorb the nitrogen oxide contained in the exhaust gas, a burner configured to increase the temperature of the exhaust gas flowing into the filter, the selective catalytic reduction converter, and the oxidation catalyst converter to set the temperature of the filter to at least a predetermined recovery temperature, thus recovering the filter, and an ECU configured to inhibit the burner from being started when the burner is otherwise to be started but if the selective catalytic reduction converter has not been activated.
