摘要： The common rail supplies a number of injectors of the cylinders of the engine, and is supplied by a constant-displacement high-pressure pump in turn supplied by a low-pressure, variable-delivery, variable-pressure, motor-driven pump. The control device has an electronic control unit for receiving signals indicating operating conditions of the engine; the suction side of the high-pressure pump has a choke; and the control unit controls the motor-driven pump to vary the fuel pressure upstream from the choke between a predetermined maximum value and a predetermined minimum value, so as to regulate the fuel intake of the high-pressure pump within a predetermined range.

摘要： The metering valve has a shutter for a discharge conduit, and an electromagnet for controlling an armature disconnected from the respective stem and sliding along the stem by means of a sleeve. The stem is guided by a fixed sleeve and is pushed by a first spring to hold the shutter in the closed position, and a second spring keeps a shoulder of the armature resting axially against a C-shaped ring fitted to the stem. To reduce the overtravel of the armature with respect to the travel of the stem to move the shutter into the closed position, and to damp oscillation of the armature, provision is made, between the two sleeves, for a bush of calibrated thickness, which slides along the stem and is such as to form a small axial clearance with the sleeves.

摘要： A metering valve has a valve body with a control chamber, a pressurized f supply conduit and a fuel drain conduit. A control rod of a shutter includes an element for hydraulically affecting the fuel supply conduit and the fuel drain conduit so that fuel drainage is considerably reduced. The control rod slides in a first cylindrical portion of the control chamber. A second portion of the control chamber that is coaxial with the first portion forms an annular shoulder against which the element is arrested. The fuel supply conduit is located radially of the first portion, and the fuel drain conduit is located axially of the second portion of the control chamber.

摘要： The device comprises a pressure pump for pumping fuel from a reservoir to aressure duct connected to an accumulator. This supplies a series of injectors for an internal combustion engine. The device further includes a pair of solenoid valves disposed between the pump and the accumulator, which are controlled by an electronic unit as a function of data on the pressure in the accumulator detected by a sensor. The solenoid valve is normally closed to discharge fuel received from the pump into the reservoir and is opened to deliver this fuel to the accumulator. On the other hand the solenoid valve is normally open to deliver fuel received to the accumulator and is closed to discharge the fuel from the accumulator into the reservoir. Between the two solenoid valves and is disposed a non-return valve.

摘要： A perfected fuel injector comprising a plunger for controlling fuel passage between an injection chamber and at least an injection orifice formed in an injection nozzel; and an electromagnetic fuel metering valve for controlling fuel passage through a drain orifice between a control chamber, supplied with fuel under pressure, and a low-pressure chamber, so as to reduce to a given value the pressure of the fuel inside the control chamber and so displace the plunger. Pressurized fuel is supplied to the injection chamber and control chamber by means of a single fitting connected to a supply pipe and coming out inside a supply orifice formed in the injector body and communicating with the control chamber and with a duct supplying fuel to the injection chamber and comprising an annular chamber and a radial hole formed in a sleeve housed in a hole on the body.

摘要： An injection system includes a high-pressure pump with at least one pumping element operated in a reciprocating manner by corresponding intake and discharge strokes. Each pumping element is equipped with a corresponding intake valve in communication with an intake line, fed by a low-pressure pump. An on-off solenoid valve is positioned on the intake line of the pump and is controlled by a control unit with a frequency equal to a whole multiple or submultiple of that of the pumping action, multiplied by a factor different from 1 and/or between 0.90 and 1.10, inclusive.
