    摘要： Even when an engine is started in various combustion states, an excessive increase in engine speed at the start of the engine is suppressed without an influence of the combustion states and with an excellent responsiveness. Ignition timing (or a combustion injection amount) at the start of an internal combustion engine is corrected in accordance with a crank angle cycle ratio which is a ratio of a combustion period crank angle cycle and a reference crank angle cycle.

    摘要： A fuel injection control apparatus is capable of reducing a minimum quantity of fuel injection without reducing a maximum quantity of injection. To open a fuel injector valve, a driving circuit supplies an electric current from a high-voltage power supply to the fuel injector. Then, after valve opening, the high-voltage power supply is switched to a low-voltage power supply, and an open state of the valve is retained. For opening the valve of the fuel injector, a microcomputer, after supplying current from the high-voltage power supply to the injector, discharges the current rapidly for a decrease below a first current level at which the open state of the valve cannot be retained. The microcomputer then controls the supply current to the injector so as to supply a current at a second current level at which the open state of the valve can be retained.

    摘要： Improving the injection fuel mass accuracy of fuel injector, it is necessary to make the fuel injector perform seat valve opening and closing operation quickly. When the shapes of a fixed core and an anchor are optimized to improve the responsiveness of a magnetic flux, it is necessary to ensure a sufficient fuel path area while preventing adhesion by making the adherence phenomenon rarely occur between an end face of the anchor and an end face of the fixed core. A through hole passes through an anchor forming an armature of an electromagnetic fuel injector from a face of the anchor where the anchor faces a fixed core to a back face where the through hole has a large-diameter portion and a small-diameter portion, and the large-diameter portion is located in an upstream part and is offset to the outer periphery with respect to the small-diameter portion.
