ABSTRACT:
A control device has a throttle valve and fuel injection valves supplying air and fuel to an internal combustion engine, a meter detecting an actual quantity of the air supplied to the engine, a sensor detecting an actual oxygen concentration of an exhaust gas outputted from an exhaust system of the engine, and an ECU controlling the valves. To regenerate an exhaust emission purifier disposed in the exhaust system at a target temperature appropriate to the regeneration of the purifier, the ECU determines a target oxygen concentration corresponding to a target air-fuel ratio and a basic air quantity according to a torque required of the engine and controls the valves according to the actual air quantity and the actual oxygen concentration to supply a basic quantity of fuel and the basic quantity of air to the engine at the target air-fuel ratio.
