摘要： A grille shutter device includes a fin unit including slat members inside an opening provided at a part of a decorative side of a vehicle front. The fin unit is configured to selectively assume a closed state and an open state, and the closed state is a state where the slat members are each disposed so as to close the opening in a vehicle front view. The open state is a state where the slat members have been moved from respective positions in the closed state to a vehicle rear side of the opening and arrayed in a row substantially along a vehicle front-rear direction.

摘要： A blowback air amount is an amount of air that is part of the air that has flowed into a combustion chamber and is blown back into an intake passage before an intake valve closes. If the blowback air amount increases, a controller causes a fuel injection valve to inject fuel by an amount increased with respect to a fuel amount for a case in which the blowback air amount remains constant. The controller sets an increase amount of fuel injected from the fuel injection valve to a greater value when the stoichiometric air-fuel ratio of the fuel injected from the fuel injection valve is small than when the stoichiometric air-fuel ratio of the fuel injected from the fuel injection valve is great.

摘要： A cooling device is employed in a vehicle including an internal combustion engine provided with a forced-induction device and an intercooler. The cooling device includes a circulation circuit configured to circulate coolant supplied to the intercooler, an electric pump configured to operate to circulate the coolant in the circulation circuit, and processing circuitry configured to control a discharge amount of the coolant of the pump. The processing circuitry is configured to execute a control amount deriving process of deriving a control amount of the pump based on a requested flow rate and a coolant temperature, and an operation process of causing the pump to operate based on the control amount when the requested flow rate is larger than 0.

摘要： A fuel injection control device for an engine includes an ECU. The ECU is configured to: change a port injection ratio in accordance with an operation state of the engine; execute correction of the total fuel injection amount by reflecting a correction amount in a basic fuel injection amount depending on the operation state when the port injection ratio is changed; and when the ECU changes the port injection ratio and calculates a second correction amount that is the correction amount having one of the positive and negative values during the execution of the correction based on a first correction amount that is the correction amount having the other one of the positive and negative values, limit reflection of the first correction amount in the basic injection amount.
