Abstract: A fuel injector has an injector body and a fitting for connecting the injector body to a high-pressure fuel supply conduit. The injector body and the fitting are separate elements of the injector, and are connected to each other to connect the supply conduit and grip an end portion of the supply conduit between the injector body and the fitting.

Abstract: The injector has a hollow body supporting an ordinary injection nozzle and a metering valve for metering the fuel to be injected; and a support defined by a sleeve and by an end wall. The sleeve houses an electromagnet controlling the metering valve, and is fitted to the hollow body. For which purpose, there is provided a leaf spring having a ring-shaped portion engaging the end wall of the support; and a number of elastic blades, each terminating with a hook-shaped appendix which engages a corresponding retaining element on the hollow body.

Abstract: The fuel premetering device has a valve controlled by an electromagnet and located between a delivery conduit of a high-pressure pump supplying fuel to a common rail, and a drain conduit for draining surplus fuel. The valve is normally closed by a spring, and the electromagnet is energized to open the valve in opposition to the spring. The electromagnet is energized by a current varying in response to the operating conditions of the engine, and which is varied by a control unit from zero, at which the valve is closed completely by the spring, to a predetermined value, at which the electromagnet opens the valve completely, so that premetering is self-adaptive.
