PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of accurately calculating a volume efficiency correction coefficient, and accurately estimating an air amount flowing into a cylinder and an external exhaust reflux amount.SOLUTION: An internal combustion engine including an exhaust reflux device comprising an exhaust reflux valve and an exhaust reflux passage calculates a volume efficiency correction coefficient as a volume efficiency equivalent value on the basis of a cylinder flow rate, an exhaust reflux amount, an intake pipe internal density and an intake pipe internal density change amount; and calculates a cylinder intake air amount and an exhaust reflux amount suctioned to a cylinder by using the calculated volume efficiency correction coefficient. |
