CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

A control device (100) for an internal combustion engine, equipped with: an in-cylinder oxygen concentration acquisition unit that obtains the oxygen concentration in the cylinders; an in-cylinder temperature acquisition unit that obtains the temperature in the cylinders; a target in-cylinder temperature acquisition unit that obtains a target in-cylinder temperature at the time of a main injection on the basis of the in-cylinder oxygen concentration obtained by the in-cylinder oxygen concentration acquisition unit; and an in-cylinder oxygen concentration control unit that, on the basis of the target in-cylinder temperature at the time of a main injection obtained by the target in-cylinder temperature acquisition unit and the in-cylinder temperature obtained by the in-cylinder temperature acquisition unit, controls the in-cylinder oxygen concentration at the time of a pilot injection performed prior to the main injection.
