Beschreibung
Zusammenfassung:	Provided is a control device for an internal combustion engine equipped with at least one cylinder, an EGR device, and an actuator that is used for control of an engine control parameter that affects the combustion stability. The control device is configured to: perform, if a condensed water occurrence condition is met, a particle size estimation processing that estimates the particle size of the condensed water that flows into the at least one cylinder from the intake channel; and perform, if the condensed water occurrence condition is met, a correction processing that corrects the engine control parameter so as to improve the combustion stability. In the correction processing, the control device more increases a correction amount of the engine control parameter when the particle size estimated by the particle size estimation processing is greater.
