  • Publication number: 20120227706
    Abstract: A fuel injection unit of an internal combustion engine includes at least an injector, an inlet opening, and an intake stroke injection device. A controller causes the intake stroke injection device to cause the injector to inject fuel in an intake stroke so that the fuel is introduced into an interior of a cylinder from the inlet opening. The fuel is injected from the injector into a range, which spreads in a width of an inside of the inlet opening when viewed from above of the cylinder, and which spreads in a width defined in a side of a center of the cylinder from a valve shaft in a state where the inlet valve is in a maximum lift-up level within the inside of the inlet opening when viewed from a lateral of the cylinder.
