。The fuel injection start timing in a prior art engine affects the fuel consumption efficiency and NOx emissions of the engine, and the effects of the fuel injection start timing on improving fuel consumption efficiency and reducing NOx are contradictory. On the other hand, in a fuel injection device with a twist/id for valve opening/closing control, the temperature of the solenoid gradually rises due to self-heating caused by energizing the solenoid and heat transfer from the engine room, and the current flows as the resistance of the coil changes. This causes a problem in that the operation of the active core is slightly affected and the start timing of fuel injection is delayed. Therefore, fine-grained feedback control of the fuel injection timing is required for optimization. Conventionally,
A device for obtaining a feedback signal for controlling the fuel injection start timing is disclosed in Japanese Utility Model Application No. 58-33774.
number is known. This device has a piezoelectric element inserted between one end of a pressure spring that urges a plunger that opens and closes a fuel injection port and a receiving surface that supports one end of the pressure spring.

It is known that a magnet piece provided at the top of the needle valve is spaced apart in the valve operating direction to detect the upward movement of the needle valve. However, in these devices, the sensor must be specially installed near the needle valve, and when applied to an injection device with a complicated structure, such as a fuel injection device with a solenoid for controlling valve opening/closing, the sensor There are disadvantages such as it is difficult to take out the lead wire, and it is also difficult to adjust or replace the sensor.

上げられノズル５は開となり燃料の噴射が開始される。Next, before explaining the operation of this embodiment, the operation of the fuel injection system shown in FIG. 1 will be explained. The now pressurized fuel is supplied from the inlet 11, and the active core 19 acts in the opposite direction via the spool 9 by the force of the upper spring 20 so that the four upper springs 10
The pressurized fuel overcomes the force and is pushed back to the nozzle 5 side, and the pressurized fuel passes through the passage 15, boat 16, sprue valve 8, and boat 13, applies pressure to the passage 14a, and the passage is closed by the check valve. Since the pressurized fuel is not sent to the annular chamber 1a and the needle valve 6 closes the nozzle 5, no fuel is ejected. Next, when a voltage I is applied to the thread/id 17, a current rises and flows to excite it, and eventually the active core 19 is attracted by overcoming the force of the upper spring 20 and is stopped by coming into contact with the end face of the adjustment bolt 21. At the same time, the spool 9 also moves along with the active core 19 by the force of the sear spring 10, and the pressure of the pressurized fuel in the passage 15 is cut off by the spool 9, and the back pressure of the check valve is released through the passage 14a1, the spool valve 8, and the passage to check the Valve opens and pressurized fuel enters inlet 11, passage 1
2. The fuel is sent to the annular chamber 1a through the check valve and passage 141) and acts on the high-pressure needle valve 6, which pushes up against the needle valve spring 7, opening the nozzle 5 and injecting the fuel. is started.

。The time when the active core 19 is attracted by the solenoid 17 and moves until it comes into contact with the end face of the adjustment bolt 21 is the time when the switching of the spool 9 is completed, and the output signal is generated before the fuel injection with a negligible time difference. It will be done. On the other hand, when the active core 19 is attracted by the energization of the solenoid 17, the solenoid excitation current waveform generates abnormal micro vibrations as shown by vl in FIG. It was confirmed that this corresponds to the time when the first peak P of abnormal vibrations occurred.

態となる。Next, the operation of the circuit shown in FIG. 2, which is a means for detecting this point P, will be explained. Connection point 17 between solenoid 17 and resistor 32
1) has a waveform as shown in FIG. 3, but the charging voltage v3 of the capacitor 34 in the integrating circuit can be changed to vl by appropriately selecting the capacitance of the capacitor 34 and the resistance value of the resistor 35. The signal waveform is close but rises a little later than the rise of vl, ha! At a point close to point P, as shown in FIG. 3, it crosses vl and becomes larger than vl, but since it is applied to the non-inverting input terminal of voltage converter VO as v2 via resistor 66, voltage converter VO
The output v4 changes to H level as shown in FIG. 3, and the timing of occurrence of the P point is detected. Voltage converter VO is H
level, the non-inverting side input terminal voltage v2 quickly rises to a high potential as shown in FIG.
4 is discharged and reset by the switch-on action of transistor TR. When the solenoid excitation current is eventually cut off, the amplifier 3 forming a set circuit for the voltage converter Va
9. Delay circuit 4os one-shot multivibrator 4
1. Due to the action of the diode D2, the voltage converter Va is turned on with a slight delay after the solenoid excitation current becomes zero.
Since the non-inverting side input terminal voltage v2 of is forced to L level, both terminal voltages (vl, v2) return to L level, and the output ■4 of voltage converter va outputs L level and is reset. It enters a state where it waits for a detection signal of the solenoid excitation current.
