Abstract: The internal combustion engine control apparatus of the invention starts gradually delaying an ignition timing ? for catalyst warm-up, immediately after a start of an internal combustion engine. When the ignition timing ? is delayed to or below a preset reference timing ?ref, a fuel amount increase flag F1 is set to 1 to start increase correction of a fuel injection amount. The internal combustion engine control apparatus then starts gradually increasing a throttle opening TH to a preset target opening THset. The increase correction of the fuel injection amount is terminated after elapse of a preset time t3 since the increase of the throttle opening TH to the preset target opening THset. This arrangement enables the increase correction of the fuel injection amount according to the requirement, thus improving the fuel economy and the emission.

Abstract: In a control device for an internal combustion engine provided with a NOx catalytic converter in an exhaust passage thereof, the progress of an undesired substance removal process is computed from the consumption of the reducing agent contained in the exhaust gas in the NOx catalytic converter.

This computation may be based on the air fuel ratio of the exhaust gas upstream of the NOx catalytic converter and the estimated consumption of the reducing agent contained in the exhaust gas or on the difference between the air fuel ratios of the exhaust gas upstream and downstream of the NOx catalytic converter. In either case, the accuracy can be improved by taking into account the space velocity of the exhaust gas.
