摘要： A control device for a hybrid electric vehicle includes an electronic control unit. The electronic control unit is configured to perform a start-up control of shifting the connection and disconnection clutch to a coupled state at the time of starting the internal combustion engine to rotate the internal combustion engine by the driving torque of the electric motor, and starting the first fuel injection mode using the direct injection injector. The electronic control unit is configured to switch from the first fuel injection mode to a second fuel injection mode for using the port injector prior to an end of the start-up control when the number of times of combustion cycles of the internal combustion engine with the first fuel injection mode reaches a predetermined first target number of times.

摘要： A heat recovery structure includes a pipe portion, a heat exchanging portion and an actuator. The pipe portion is inclined such that a side face of the pipe portion faces a diagonally lower side, and is configured such that exhaust gas from an engine circulates through the pipe portion. The heat exchanging portion is configured to communicate with the pipe portion and to perform heat-exchange between a heat medium and the exhaust gas flowing into the heat exchanging portion from the pipe portion such that the exhaust gas thus subjected to the heat-exchange with the heat medium flows out to the pipe portion. The actuator is configured to operate a selector valve configured to switch between a state where the exhaust gas circulates through the pipe portion and a state where the exhaust gas circulates through the heat exchanging portion.

摘要： A hybrid electric vehicle includes an engine having an in-cylinder injection valve, a fuel supply device that supplies fuel to the in-cylinder injection valve, a motor that can generate an electric power through the use of a motive power output from the engine and can output a running motive power, and an electrical storage device that exchanges electric power with the motor. A deposit removal process where deposits adherent to the in-cylinder injection valve are removed by setting a pressure of fuel supplied to the in-cylinder injection valve to a predetermined pressure higher than a normal pressure and injecting fuel from the in-cylinder injection valve is performed during the performance of a forcible charging process for the electrical storage device, and the forcible charging process is continued until the pressure of fuel is returned to the normal pressure after the end of the deposit removal process.

摘要： A controller controls a hybrid electric vehicle. The hybrid electric vehicle includes an engine, a motor arranged in a power transmission path between the engine and a drive wheel, and a clutch arranged in the power transmission path between the engine and the motor. The controller idles the engine in accordance with a target engine rotation speed and operates the motor in accordance with a target motor rotation speed when the clutch is in a disengagement state. When the clutch is in the disengagement state and the engine is idling, the target motor rotation speed is less than the target engine rotation speed.

摘要： When the vehicle is stopped and removal of deposits is not required, and forced charging of a power storage device is not being performed, the controller controls the fuel supply device so that a supply fuel pressure is at the first fuel pressure. When the vehicle is stopped and the removal of deposits is required, and the forced charging of the power storage device is being performed, the controller controls the fuel supply device so that the supply fuel pressure is at a second fuel pressure higher than the first fuel pressure. When the vehicle is stopped and the removal of deposits is required, and the forced charging of the power storage device is not being performed, the controller controls the fuel supply device so that the supply fuel pressure is at a third fuel pressure higher than the first fuel pressure and lower than the second fuel pressure.

摘要： An engine device includes an engine including an in-cylinder injection valve and a spark plug, an exhaust gas control device, and a controller. The controller is configured to perform a last fuel injection from the in-cylinder injection valve in an expansion stroke and to set a fuel injection amount for the last fuel injection in expansion stroke injection driving, based on a coolant start temperature, post-start time, and volumetric efficiency. The expansion stroke injection driving is a control that is performed by performing the ignition by the spark plug in synchronization with the fuel injection in the expansion stroke.
