摘要： In a predetermined operating region, a fuel injection valve executes a second injection to inject fuel into a cylinder in a compression stroke, and a first injection to inject fuel into the cylinder 2 in the compression stroke or an intake stroke before the second injection. When a purge is executed, the total quantity of fuel to be injected by the fuel injection valve into the cylinder is reduced more than when the purge is not executed, and a fuel reduction quantity of the second injection is made smaller than a fuel reduction quantity of the first injection.

摘要： An engine control device is provided, which includes a blowby gas passage connecting an engine body to an intake passage so that blowby gas leaked from a combustion chamber is recirculated to the intake passage, a boost pressure changer configured to change a boost pressure of a turbocharger, and a controller configured to set a target boost pressure and control the boost pressure changer. The turbocharger includes a turbine which is provided to an exhaust passage and driven by exhaust gas, and a compressor which is provided to the intake passage and rotary driven by the turbine to boost intake air. The blowby gas passage is connected to the intake passage near the compressor. The controller corrects the target boost pressure when an ambient temperature is below a given determination temperature, to be higher than the target boost pressure when the ambient temperature is at or above the determination temperature.

摘要： A driving system for a vehicle includes an engine including a fuel injection valve, an electric motor, a hydraulic clutch which connects/disconnects the engine to/from the motor, a hydraulic pressure sensor which detects hydraulic pressure of the clutch, and a controller which selectively executes one of a motor travel mode where the motor is activated and the engine is stopped, and an engine travel mode where at least the engine is activated. In a startup of the engine accompanying a change from the motor travel mode to the engine travel mode, the controller causes the clutch to transition from a disconnected state to a connected state, determines the connected state of the clutch based on hydraulic pressure detected by the hydraulic pressure sensor, and when the clutch is confirmed to be in a predetermined connection initial state, the controller causes the fuel injection valve to inject fuel.
