Abstract:
An internal combustion engine includes a turbocharger, a variable valve timing mechanism, a variable compression ratio mechanism, and an electronic control unit that controls the variable compression ratio mechanism such that the mechanical compression ratio becomes a target mechanical compression ratio and controls the variable valve timing mechanism such that the valve closing timing of the intake valve becomes a target valve closing timing. The electronic control unit brings the target valve closing timing close to an intake bottom dead center and make the target mechanical compression ratio low, compared to a steady state after the intake pressure reaches a target pressure, in a transient state before the intake pressure reaches the target pressure in a case where the intake pressure is increased to the target pressure higher than an atmospheric pressure by the turbocharger.

Claim (Index 4):
The internal combustion engine according to  claim 2 , wherein:\n the electronic control unit is configured to calculate a steady compression ratio that is a target value of the mechanical compression ratio in the steady state, and a transient compression ratio that is a target value of the mechanical compression ratio in the transient state; and the electronic control unit is configured to calculate the target mechanical compression ratio based on the steady compression ratio and the transient compression ratio.
