A method and a device for controlling an exhaust emission from an internal combustion engine excellent also in the removal of particulates from the exhaust emission exhausted from the internal combustion engine, particularly a diesel engine. The method uses the exhaust emission control device comprising an oxidation area in which an oxidation catalyst carrying both platinum and palladium along the flow of the exhaust emission is installed in the exhaust passage of the internal combustion engine and a filtrating area in which a particulate filter is installed. The method and the device are characterized in that a hydrocarbon-based liquid is supplied to the exhaust emission inflow side of the oxidation area when the particulates of 2 to 10 g per liter of the particulate filter are collected, and the exhaust emission is heated to a temperature of 550°C or higher by the oxidation catalyst to burn residue in the particulate filter.
