    • A direct injection spark ignition internal combustion engine including a controller that controls a fuel injector to perform a plurality of fuel injections to inject a necessary amount of fuel during an intake stroke, or from an intake stroke to a first half of a compression stroke, when homogeneous combustion is to be performed. The fuel injection control sets an injection prohibition period, in which injection of the fuel is prohibited, to a middle of the intake stroke. The injection prohibition period is decreased as the engine speed and as the intake air pressure increase. In addition, the amount of fuel injected before the injection prohibition period is reduced, and the amount of fuel injected after the injection prohibition period is increased, as the engine speed decreases.

    • A wall shape of a cavity consists of an inward protruding portion located at the periphery of an opening, a center portion projecting toward a fuel injector, and a peripheral portion connecting the inward protruding portion and the center portion. The fuel injector and the cavity are configured so that fuel injected from fuel injector directs to the proximity of the border between the inward protruding portion and the peripheral portion. The peripheral portion consists of a first portion located farthermost from the fuel injector, a second portion located between the inward protruding portion and the first portion, and a third portion located between the first portion and the center portion. The radii of arcs of the peripheral portion decrease from the second portion to the first portion and increase from the first portion to the third portion.

    • A method and a device for operating an internal combustion engine and an internal combustion engine are described, the fuel being injectable directly into a combustion chamber in particular via at least one first injector and also being injectable into an intake manifold in particular via at least one second injector. For injection of fuel in a full-load operating state of the internal combustion engine, a first selection is made from the at least one first injector and the at least one second injector having a first metering range, including a full-load injection quantity required for the full-load operating state. For injection of fuel in a partial-load operating state of the internal combustion engine, a second selection is made from the at least one first injector and the at least one second injector having a second metering range, including the adjustment of a minimum fuel injection quantity required for operating the internal combustion engine. The first selection and the second selection are made differently, in such a way that only the metering range of the first selection includes the full-load injection quantity and/or that only the metering range of the second selection covers the minimum fuel injection quantity required for operating the internal combustion engine.

    • A common rail injection system for internal combustion diesel engines is provided which is designed to correct a limit of width of an ineffective injection command pulse signal which is to be applied to each fuel injector, but causes the injector to produce no spray of fuel in order to minimize a variation in quantity of fuel injected to the engine between the injectors arising from the individual variability or aging of the injectors. The system works to changes the width of a pilot injection command pulse signal to search a value thereof when an engine operation variation such as a change in speed of the engine exceeds or decreases below a threshold at which the injector may be viewed as having sprayed the fuel actually or stopped spraying the fuel actually and determines the limit of width of the ineffective injection command pulse signal using the searched value.

    • A method for controlling fuel injection into a direct injection, compression-ignition internal combustion engine is provided. The engine preferably comprises a diffusion-combustion engine equipped with a fuel-injection system comprising a high-pressure fuel system and a plurality of fuel injectors each adapted to inject fuel directly into a combustion chamber of the engine and a controller. The controller is adapted to monitor engine operation and an operator torque request, and determine a quantity of fuel to inject into one of the combustion chambers during a combustion cycle. Each fuel injector is actuated to selectively execute one of one, two, and three fuel injection events to deliver the determined quantity of fuel to the combustion chamber during the combustion cycle.
