Abstract: PROBLEM TO BE SOLVED: To provide a technique capable of more suitably reducing NOx stored in a NOx catalyst in an exhaust emission control system for an internal combustion engine.
SOLUTION: When NOx stored in the NOx catalyst is reduced, an air-fuel ratio of perimeter atmosphere of the NOx catalyst is reduced to a target air-fuel ratio by reducing an air-fuel ratio of exhaust gas discharged from the internal combustion engine.

Abstract: PROBLEM TO BE SOLVED: To effectively suppress deterioration of emission and fuel economy due to effect of exhaust valve opening timing during acceleration in a control device for an internal combustion engine.
SOLUTION: An upper limit value of a fuel injection amount is set based on the exhaust valve opening timing of the internal combustion engine. When increasing the fuel injection amount during acceleration, the fuel injection amount is restricted to the upper limit value or less. The exhaust valve opening timing wherein the upper limit value of the injection amount is the maximum is comparatively early in a low speed area. The timing moves toward a delaying direction as the engine speed rises from that point toward an intermediate speed area, and moves toward an earlier direction as the engine speed rises from that point to a high speed area.
