Control device for internal combustion engine

A control device for an internal combustion engine, comprising

• an ignition control unit that controls energization of an ignition coil that supplies electric energy to an ignition plug that discharges in a cylinder of the internal combustion engine to ignite fuel,
• wherein the ignition coil includes a primary coil disposed on a primary side, and a secondary coil disposed on a secondary side, and
• wherein the ignition control unit
• controls the energization of the ignition coil such that, by a first induced current flowing through the secondary coil and a second induced current flowing through the secondary coil in superposition with the first induced current based on a primary current flowing through the primary coil, the ignition coil releases first electric energy and, in addition, releases second electric energy in superposition with the first electric energy;
• and
• controls the energization of the ignition coil such that, by the second induced current being cut off when the first induced current becomes equal to or less than a predetermined first set value, the ignition coil stops the releasing of the second electric energy at a timing depending on a state of a gas around the ignition plug to stop the discharge of the ignition plug.
