摘要： A device is provided, which controls a vehicle-mounted engine provided with an engine body with a plurality of cylinders, a plurality of independent intake passages, each connected to the engine body so as to communicate with a combustion chamber of each cylinder via an intake port, and a surge tank connected to an upstream end of each independent intake passage. The device includes a phase changer, an ambient temperature sensor, and a controller configured to acquire an amount of condensate water existing in the surge tank. When the engine is stopped in a situation where the ambient temperature is lower than a given reference temperature and the condensate water amount is above a given reference amount, the controller controls the phase changer so that a lift amount of an intake valve in each cylinder of the stopped engine becomes outside a given minute lift range.

摘要： An engine control system comprises: an engine 10 capable of switching between a reduced-cylinder operation mode in which combustion is stopped in a part of a plurality of cylinders 2 and an all-cylinder operation mode in which combustion is performed in all the plurality of cylinders 2; and a PCM 50 configured to stop fuel supply to the cylinders 2 when a given fuel cut-off condition is satisfied. The PCM 50 is operable, during a transition from a state in which the engine 10 is operated in the reduced-cylinder operation mode to a state in which the fuel cut-off condition is satisfied, to stop the fuel supply to the cylinders 2 at a timing earlier than that during a transition from a state in which the engine 10 is operated in the all-cylinder operation mode to the state in which the fuel cut-off condition is satisfied.

摘要： A supercharging device for an engine is provided, which includes a supercharger provided to an intake passage of the engine, an actuator configured to drive the supercharger, and a controller including a processor configured to control the actuator to drive the supercharger when an operating state of the engine is in a given supercharging range, and to stop the supercharger when the operating state is in a non-supercharging range. The controller causes the actuator to forcibly drive the supercharger in the non-supercharging range when a temperature of the supercharger is lower than a preset temperature, and prohibits the forcible drive of the supercharger when a rotation speed of the supercharger during the forcible drive of the supercharger is lower than a preset rotation speed.

摘要： To provide a control device for a vehicle capable of controlling the torque of a drive source so as to appropriately balance the suppression of body vibrations and the securing of a transient response during acceleration or deceleration. This control device for a vehicle includes an accelerator position sensor that detects the accelerator opening, a torque adjustment mechanism such as a throttle valve that adjusts the torque of an engine as the drive source of the vehicle, and a powertrain control module (PCM) that controls the torque adjustment mechanism based on the accelerator opening. The PCM sets the target acceleration of the vehicle based on the accelerator opening, sets the target torsion angle of the drive shaft based on the target acceleration, sets the target torque of the engine based on the target torsion, and controls the torque adjustment mechanism based on the target torque.
