    摘要: In a fuel injection device, a driving unit structure has a magnetic aperture (201), in which an inner diameter is gradually enlarged toward the mover (102) side, provided in an inner peripheral surface of the magnetic core (107). It is possible to reduce magnetic delay time upon valve opening from the supply of the electric current to the coil to the rise of magnetic flux and magnetic delay time upon valve closing from the stoppage of the electric current to the coil to reduction of magnetic flux, by providing a magnetic aperture (201) in the inner peripheral surface of the magnetic core (107). Thus it is possible to improve the dynamic responsiveness upon valve opening and valve closing.

    摘要: A control apparatus for a direct injection type engine 1 is provided for reducing an amount of fuel that adheres to and that remains on a crown surface of a piston 207a so as to suppress the increase of Number of particles as well as advancing the first injection as much as possible when plural fuel injections are carried out in one cycle in the direct injection type engine 1. The first injection timing is set based on a pulse width of at least the first injection among each of injections split plural times, and when the pulse width of the split first injection is short, the injection timing of the first injection is more advanced as compared with a case of a longer pulse width of the split first injection.

    摘要: The present invention relates to a multihole injector. Each of the injection holes (71-76) of the multihole injector has an inclined angle with respect to a center line of an injection valve main body (1) as well as the inclined angle of each of the injection holes (71-76) is provided with a predetermined offset amount with respect to a target inclination angle of a center of gravity position of each of the injected fuel sprays (91-96). The predetermined offset amount is set based on a correction amount for correcting positional drift with respect to the target direction of the center of gravity position of the fuel spray.

    摘要: To improve the injection fuel mass accuracy of a fuel injector, it is necessary to make the fuel injector perform seat valve (114B) opening and closing operation quickly. When the shapes of a fixed core (107) and an anchor (102) 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 (102) and an end face of the fixed core (107). To achieve the above object, in the invention, a through hole (170-173) passing through an anchor (102) forming an armature (114) of an electromagnetic fuel injector from a face of the anchor (102) facing a fixed core (107) to a back face is formed so that the through hole (170-173) has a large-diameter portion and a small-diameter portion.

    摘要: The drive device is configured to, during a time interval between an earlier fuel injection (first fuel injection) and a later fuel injection (second fuel injection), supply an electromagnetic coil with an intermediate current at a voltage with a level of not opening the valve. Further, the drive device sets a voltage application for supplying the intermediate current to initiate before a valve closing in the earlier fuel injection and terminate before half a period of time between a first instant when the valve is closed in the earlier fuel injection and a second instant when a supply of a drive current for opening the valve is initiated in the later fuel injection.
