Abstract:
A control device for an internal combustion engine includes an electronic control unit configured to perform dither control processing for controlling the fuel injection valve based on a requested injection amount such that a part of cylinders among a plurality of cylinders becomes a lean combustion cylinder and cylinders different from the part of cylinders among the cylinders become a rich combustion cylinder, and restriction processing for, in a case where the requested injection amount is equal to or greater than a first injection amount, making no restriction on the dither control processing, and in a case where the requested injection amount is within a second injection amount range of an injection amount smaller than the first injection amount, restricting the dither control processing to a side where a leaning degree of an air-fuel ratio of a cylinder having a leanest air-fuel ratio among the cylinders decreases.

Claim (Index 1):
A control device for an internal combustion engine, the internal combustion engine including a plurality of cylinders, a catalyst configured to process exhaust gas discharged from the cylinders, and fuel injection valves respectively provided in the cylinders, the control device comprising an electronic control unit configured to perform\n calculation processing for calculating a requested injection amount according to an operation point of the internal combustion engine, dither control processing for controlling the fuel injection valve based on the requested injection amount such that a part of cylinders among the cylinders becomes a lean combustion cylinder having an air-fuel ratio leaner than a stoichiometric air-fuel ratio, and cylinders different from the part of cylinders among the cylinders become rich combustion cylinder having an air-fuel ratio richer than the stoichiometric air-fuel ratio, and restriction processing for, in a case where the requested injection amount is equal to or greater than a first injection amount, making no restriction on the dither control processing, and in a case where the requested injection amount is within a second injection amount range of an injection amount smaller than the first injection amount, restricting the dither control processing to a side where a leaning degree of an air-fuel ratio of a cylinder having a leanest air-fuel ratio among the cylinders decreases.
