摘要
An exhaust gas purifying apparatus and method for an internal combustion engine are provided for appropriately regenerating a filter by supplying neither too much nor too less intake air when the filter is regenerated by supplying an unburnt fuel into exhaust gases. A filter is disposed in the exhaust system for collecting particulate matters included in exhaust gases. An ECU instructs to burn particulate matters deposited in the filter to execute a regenerating operation for regenerating the filter. An intake throttle valve adjusts the amount of intake air flowing through an intake system of the internal combustion engine. The ECU controls the intake throttle valve to narrow down an opening of the intake throttle valve during execution of the regenerating operation by the regenerating operation executing means. The ECU also corrects the opening of the intake throttle valve in accordance with at least one of the temperature of the internal combustion engine, the atmospheric pressure, and the intake air temperature detected by at least one of sensors.
