摘要： PROBLEM TO BE SOLVED: To provide a fuel injection system comprising a high-pressure pump without generating relatively long-term pressure vibration in common rail pressure. SOLUTION: This injection system comprises the high-pressure pump 7 having at least one pumping element 18 operated in a reciprocating manner by means of corresponding intake and discharge strokes. Each pumping element 18 is equipped with a corresponding intake valve 25 in communication with an intake line 10 and supplied with fuel by a low-pressure pump 9. An opening-closing type solenoid valve 27 is positioned on the intake line 10 of the pump 7, and is controlled by a control unit 16 with a frequency equal to an integral multiple or submultiple of integer number of the frequency of the pumping action, multiplied by a factor K slightly different from 1.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection device and its manufacturing method for restraining cost. SOLUTION: This fuel injection device is composed of a hollow body for storing a throttle valve for injection, and the valve has a calibration pipe for discharging fuel from a control chamber. The calibration pipe is normally closed and held by a shutter controlled by an electromagnet composed of a magnetic core and an electric coil stored in an annular slot of the core. The coil has a cylindrical outside surface, and the outside surface forms a clearance surrounded by the fuel sent out of the calibration pipe together with the annular slot. The coil is particularly composed of a bobbin having a pair of branch parts for supporting a pair of plugs for supplying electricity of the coil. The plugs are included in a block of at least a partially nonmagnetic material. The bobbin has a substantially cylindrical rib and flanges parallel in two planes. One of the flanges is adjacent to an end part of the plugs, and the other has a small diameter for forming a flow passage for the fuel between the calibration pipe and the clearance.

The control chamber has an inlet 18 with a diameter D 4 and an outlet passage 24 having a diameter D 5 and controlled by a control valve 16. The method for fuel injection comprises the step of selecting the ratio D 5 /D 4 of the diameters to determine the rate of the displacement of the needle 7 and the step of transmitting a first electric command C 1 and a second electric command C 2 adjacent to each other to the device 8 to move the needle 7 in the profile P operated continuously with time.
