Internal combustion engine system

An internal combustion engine system comprising:

• an internal combustion engine including a cylinder, an intake valve and an exhaust valve that open and close the cylinder, a cylinder injection valve that directly injects fuel containing alcohol into the cylinder, and a variable valve drive mechanism that forms a valve closed period from when the exhaust valve is closed to when the intake valve is opened;
• and
• a control device that controls the cylinder injection valve and the variable valve drive mechanism,
• wherein the control device includes
• a calculation unit that calculates a first crank angle section where a temperature of the cylinder is equal to or higher than a boiling point of the fuel in a compression stroke and a second crank angle section where the temperature of the cylinder is equal to or higher than the boiling point of the fuel in the valve closed period, before completion of warming-up of the internal combustion engine, and
• an injection controller that executes fuel injection in the first and second crank angle sections by the cylinder injection valve.
