Abstract
A control device for an internal combustion engine includes an electronic control unit. The electronic control unit controls a fuel injection valve to inject at least primary fuel and secondary fuel in this order such that a pattern of a pressure increase rate in the combustion chamber includes a first peak and a second peak, controls an injection timing and an injection amount of each of the primary fuel and the secondary fuel such that a second peak value becomes higher than a first peak value, controls an intake device such that oxygen density is increased along with an increase in a load, and controls the injection timing and the injection amount of each of the primary fuel and the secondary fuel such that a peak difference acquired by subtracting the first peak value from the second peak value is increased as the load is increased.
