Abstract: An engine unit includes an engine including a cylinder injection valve that sprays fuel into a combustion chamber and an ignition plug that is able to ignite fuel sprayed from the cylinder injection valve. When expansion stroke injection drive of performing final fuel injection from the cylinder injection valve in an expansion stroke and igniting the fuel using the ignition plug in synchronization with the fuel injection in the expansion stroke is performed, upper and lower limits of an ignition timing are guarded such that the ignition timing is in a predetermined range centered on a final fuel injection start timing at a final determination timing of the ignition timing.

Abstract: A control apparatus for a vehicle that includes an engine as a drive power source, a rotating machine as an electric power generator, and an electric storage device. The control apparatus executes an automatic drive control for automatically controlling a torque of the drive power source in accordance with a requested drive torque without requiring an acceleration/deceleration operation by a driver of the vehicle. During an engine running of the vehicle, the rotating machine is rotated by the engine to generate an electric power, and a charging amount, by which the electric storage device is to be charged, is controlled by controlling the electric power generated by the rotating machine. The control apparatus is configured, during an automatic driving of the vehicle, to set the charging amount such that the charging amount is smaller when the requested drive torque is small than when the requested drive torque is large.

Abstract: A vehicle includes: an internal combustion engine including a fuel injection valve, a spark plug, and an electrically powered motor that rotates a crankshaft; and a controller that causes the internal combustion engine to start in a case where a starting condition is established while the internal combustion engine is stopped. The controller is configured to perform, when the starting condition is established, a first firing-combined starting that injects fuel into the combustion chamber by means of the fuel injection valve and performs, for a first time, a firing that ignites the injected fuel by means of the spark plug and, together therewith, starts driving of the motor, and after the speed of the internal combustion engine exceeds a predetermined determination threshold value that is greater than a resonance band, performs the firing for a second and succeeding times in sequence.

Abstract: When a start condition is satisfied after the internal combustion engine has been stopped according to an automatic stop control, a control apparatus reversely rotates the engine to compress an air in an expansion stroke cylinder at that time point, and thereafter generates a first time combustion. The apparatus determines whether the start condition becomes satisfied based on a first start request owing to a driving operation by a driver of a vehicle on which the engine is mounted. When the start condition becomes satisfied based on the first start request, the control apparatus makes a maximum value of an engine generating torque by the first time combustion and/or a maximum torque of the engine generating torque by a second time combustion larger as compared to when the start condition becomes satisfied based on a second start request other than the first start request.

Abstract: A control device is applied to a hybrid vehicle (1A) in which an internal combustion engine (2) and an MG (3) are connected through a second clutch (21), the MG (3) and a transmission (10) are connected through a first clutch (20) whose state is switchable by a depression operation of a clutch pedal (CP), and an output shaft (12) of the transmission (10) is connected to a driving wheel (5) so as to transmit power. The control device starts the internal combustion engine (2) when an accelerator opening is equal to or greater than a start determination value. When the vehicle (1A) is stopped and the internal combustion engine (2) is stopped, and when the amount of return of the clutch pedal (CP) is small, the control device makes the start determination value greater than when the amount of return of the clutch pedal (CP) is great.
