Abstract: A fuel injection control device has a detection unit (56), a correction value calculation unit (S12, S13), and a conduction time calculation unit (S15). The detection unit detects a current increase speed that is a speed of increasing an electric current flowing in an electromagnetic coil in accordance with the start of conducting the electromagnetic coil during partial lift injection in which a valve body starts valve closing operation before the valve body reaches a maximum valve opening position after the valve body starts valve opening operation. The correction value calculation unit calculates a correction value for a requested injection quantity on the basis of the detected current increase speed. The conduction time calculation unit calculates a conduction time of the electromagnetic coil during the partial lift injection on the basis of the requested injection quantity corrected by the correction value.

Abstract: A method for controlling a plurality of injectors installed in the same cylinder of an engine may include determining whether an electrical failure occurred in any of the injectors, and entering a fail-safe mode when an electrical failure has occurred only in one of the plurality of injectors in the same cylinder. In the fail-safe mode, fuel supply to an injector that has experienced an electrical failure is cut off, and the amount of fuel injected into the cylinder by a normally operating injector is increased.

Abstract: An electromagnetic device, such as an actuator for electrovalves or injectors, particularly for endothermal engines includes a coil winding of an electric wire covered with an insulating layer made of overmoulded plastic material. In order to prevent the electric wire from breaking at the ends thereof connected to the electric terminals, a protective insert is applied prior to the plastic moulding step. The insert is also made of thermoplastic material, so that it can melt locally together with the cover material, thereby ensuring a stable and effective union during the moulding process. The invention also relates to a process for manufacturing the device. An electromagnetic device, such as an actuator for electrovalves or injectors, particularly for endothermal engines includes a coil winding of an electric wire covered with an insulating layer made of overmoulded plastic material.

Abstract: The present disclosure provides a method for operating an injector of an internal combustion engine, the nozzle needle of said injector being operated by a piezo actuator by means of a servo valve. The method may include eliminating the idle travel of the piezo actuator by maintaining a permanent direct force connection between the piezo actuator and the servo valve, so that a change in force on the servo valve due to a change in pressure in the valve chamber when the servo valve is opened and closed and when the nozzle needle of the injector is closed is always transmitted to the piezo actuator as a change in force, detecting the resulting change in voltage and/or capacitance of the piezo actuator, and ascertaining parameters with which the injection quantity which is output by the injector is regulated based on the result of the detection. The present disclosure provides a method for operating an injector of an internal combustion engine, the nozzle needle of said injector being operated by a piezo actuator by means of a servo valve.
