<p>PROBLEM TO BE SOLVED: To properly suppress knocking at each cylinder of an internal combustion engine.SOLUTION: A control device of an internal combustion engine which senses the presence/absence of knocking at a plurality of cylinders, and performs correction control for suppressing the knocking when the knocking is generated adjusts a correction amount by the correction control on the basis of in-cylinder pressure which is detected in each cylinder. Concretely, by delaying ignition timing with respect to the cylinder which is high in the in-cylinder pressure in an expansion stroke, that is, the cylinder which is high in a risk of the generation of the knocking, and by advancing ignition timing with respect to the cylinder which is low in the in-cylinder pressure in the expansion stroke, that is, the cylinder which is low in the risk of the generation of the knocking, an output and the fuel economy performance of the internal combustion engine are improved while properly suppressing the knocking.</p> |
