Abstract: In an exhaust gas temperature raising control for recovering purification ability of an exhaust gas purification device (12) of an internal combustion engine, the exhaust gas temperature is efficiently raised to a target level with white smoke prevented from being produced.

Abstract: An exhaust gas purification control apparatus for an internal combustion engine instructs an exhaust fuel valve to inject additive fuel when a diesel particulate filter is to be regenerated, and determines that both the exhaust fuel valve and an oxidation catalyst are normal if an exhaust temperature rises. If the exhaust temperature does not rise, the control apparatus instructs an engine fuel valve to inject additive fuel as a post-injection. If the exhaust temperature does not rise, the control apparatus determines that the oxidation catalyst is abnormal. If the exhaust temperature rises, the control apparatus determines that the oxidation catalyst is normal but the exhaust fuel valve is abnormal.

Abstract: In regeneration control of an exhaust gas purification system (1) equipped with NOx occlusion reduction catalyst (11), a decision is made whether operating state of an engine is in a first engine operating range where the exhaust gas temperature is lower than a predetermined mode judgment temperature. If yes, EGR rich control is performed. Otherwise, injection rich control in exhaust pipe is performed. When EGR rich control is performed, a decision is made whether a vehicle is under acceleration or not. If a decision is made that the vehicle is under acceleration, regeneration control is postponed until that decision ends. This enables rich control for regeneration the NOx occlusion reduction catalyst (11), while avoiding deterioration in drivability (comfortableness) during acceleration of the vehicle.

Thus, in the regeneration control in the manual regeneration mode of a continuous regeneration type DPF device (12) of an engine(10), temperature rise of an engine cooling water can be restricted without stopping an air conditioner, and possible overheat of the engine (10) can be prevented.
