Definitions
- the invention relates to a fuel injection device, in particular for an internal combustion engine, and to its control method.
- Document FR 2 854 664 discloses an injection device comprising a tubular body in which a needle is mounted.
- the needle is terminated by a valve head with a seat carried by the end of the tubular body.
- Pressurized fuel feeds the inside of the tubular body and is stopped by the valve.
- the needle has a longitudinal housing in which is placed an electroactive material. When the electroactive material is excited, it elongates, causing the elastic elongation of the needle and thus the detachment of the head relative to the seat.
- the valve is then opened and the fuel passes between the seat and the head to be injected into a combustion chamber.
- the response time to operate the maximum lift of the valve is very short, typically less than 50 microseconds. It is therefore possible to control the degree of opening of the valve substantially at each moment during the injection phase. This controls the instantaneous flow of fuel and the formation of fuel droplets.
- the element electro-active is in the immediate vicinity of the head.
- the electro-active element can be raised to temperatures likely to degrade its operation.
- its location near the nose of the injector can cause congestion problems.
- the subject of the invention is a fuel injection device comprising a cylindrical body, a needle whose one end comprises a head forming a valve on a seat carried by one end of the cylindrical body, an actuator with electro-magnetic material. -Active, the actuator having a bar and being able to cause a displacement of the head to open the valve, a flyweight extending the bar, a prestressing device holding the needle and the flyweight bearing against opposite ends of the bar.
- the needle extends coaxially with the cylindrical body in the form of a rigid bar, the needle being able to enter into axial resonance when it is subjected by the actuator to axial pulses at a determined excitation frequency, thus superimposing a vibratory movement of the head to the overall motion of the needle.
- the length of the bar allows to place 1 'actuator in the body of the device away from the head, and therefore to be less exposed to the heat of the combustion chamber.
- the excitation frequency is chosen close to a self-mode frequency of the needle so as to obtain a resonance phenomenon by successions of compression and extensions of the needle in the axial direction. Furthermore, the fact of being able to resonate the bar in the axial direction of the device makes it possible to obtain a mode of displacement of the head in the axial direction at the chosen excitation frequency.
- the chosen frequency is for example such that the oscillation period is much shorter than the duration of an injection phase. Oscillations of the head can modulate the fuel flow and thus control the formation of very fine fuel droplets.
- the excitation frequency is in a range extending from 10 to 30 kHz. It is thus possible to obtain the formation of very fine droplets during the injection phase.
- the bar is made of magnetostrictive material and is surrounded by a coil capable of creating a magnetic field in the bar.
- a coil capable of creating a magnetic field in the bar.
- the needle When such material is subjected to a magnetic field, it undergoes an elongation which is transmitted to the needle.
- the needle then moves axially in the direction of an opening of the valve. According to the frequency of the magnetic field, the needle moves as a whole, for a low frequency, or lengthens and retracts into resonance if the magnetic field is at an excitation frequency capable of resonating the needle, that is, close to a self-mode frequency of the needle.
- a tube of ferromagnetic material surrounds the coil.
- the magnetic field created in the bar is looped on itself thanks to the tube, which increases the efficiency of the coil.
- the bar is made of piezoelectric material.
- the impedance of the flyweight is greater than the impedance of the needle.
- Impedance is defined by the product of density and acoustic celerity in the constituent material of the flyweight. Impedance characterizes the dynamic behavior of the material. As the impedance of the flyweight is greater, the displacement caused is mainly reflected on the needle, in the form of a deformation or displacement. Thus, even if the weight is not fixed to the body of the device, the assembly formed by the needle, the bar and the flyweight behaves, at the frequencies used, as if the flyweight was fixed.
- the prestressing device comprises a tubular sleeve containing the weight and one actuator, a biasing spring bearing on the sleeve and tending to push the counterweight against the bar, and an elastic washer, the needle having a collar , the spring washer bearing on the flange to compress the needle against the bar.
- Preloading in compression of the bar makes it possible to increase the amplitude of operation of the bar.
- the application of the prestressing also makes it possible to apply the weight and the needle against the bar.
- the movement of the end of the bar in contact with the needle is allowed by the elastic deformation of the washer.
- the assembly comprising the needle, the prestressing device and the actuator is slidably mounted in the cylindrical body, bearing means acting on said assembly and tending to put the head bearing against the seat.
- the subject of the invention is also a method of control of an injection device as described above, according to which an injection phase is controlled by applying to the actuator a continuous signal during the duration of the injection and a periodic signal at an excitation frequency suitable for cause resonance of the needle.
- the continuous signal has the effect of controlling a movement of the needle as a whole, while the periodic signal has the effect of putting the needle into resonance.
- One can modulate the amplitude of the displacement of the needle as well as the amplitude of its oscillations. The amplitude of these two signals can be modulated during an injection phase.
- a damping signal obtained by the inverse transform of the simulated oscillatory movement of the head is superimposed in the event of the control signal being cut off. If the control signal is abruptly cut, the head of the needle returns to the position against the seat with a high speed because of the superposition of the two signals, which generates a shock. By simulating the movement of the head in the absence of the seat, an oscillatory movement is obtained around the rest position of the head. By applying an inverse transform to this oscillatory motion, a damping signal is obtained which, when applied to the control signal, provides a cushioned movement of the head. It then gently docking the seat at the end of the injection period.
- Figure 1 is a longitudinal sectional view of a device according to one invention.
- An injection device 1 according to the invention is for injecting fuel into a combustion chamber of an internal combustion engine or in an air intake duct, not shown.
- the injection device comprises a cylindrical body made in two parts, a front portion 10 and a rear portion 11 coaxial, assembled together by screwing by a sleeve 12.
- the front portion 10 of the cylindrical body has a bore 15 coaxial with the cylindrical body and a seat 14 at one end of the front portion 10.
- a needle 2 is slidably mounted in the bore 15. It comprises a head 20 forming a valve with the seat 14.
- a channel 16 is formed in a space between the bore 15 and the needle 2 to channel fuel to the seat 14. The channel 16 is fed by a conduit 13 extending into the cylindrical body from an orifice connection 17.
- the rear portion 11 of the cylindrical body comprises a tubular sleeve 37 slidably mounted along the axis of the cylindrical body.
- the tubular bushing 37 is forced backwards by a bushing spring 4 bearing on a first shoulder 110 of the cylindrical body and a second shoulder 370 of the tubular bushing 37.
- the needle 2 has at its end opposite the head 20 a flange 21 on which an elastic washer 33 is supported.
- the spring washer 33 is also in abutment against a third shoulder 371 of the tubular sleeve 37 so as to transmit the tension of the socket spring 4 to the needle 2 by means of the spring washer 33, and thus to press the head 20 of the needle against the seat 14.
- the injection device 1 comprises, in the extension of the needle 2 towards the rear, an actuator 3 with an electro-active material and a flyweight 34.
- the actuator 3 comprises a bar 30 made of magnetostrictive material. surrounded by a coil 31 and a tube of ferromagnetic material 32.
- the bar 30 is for example made of Terfenol (registered trademark).
- the bar 30 is compressed by a prestressing device comprising a preload spring 35 bearing on a nipple 36 screwed into the sleeve 37 and tending to push the weight 34 against the bar 30.
- the tube of ferromagnetic material 32 is fitted on a cylinder guide 340 made at the end of the weight 34 on the side of the bar 30.
- the weight 34 is made of a material so that the impedance is greater than the impedance of the needle.
- the weight 34 is for example tungsten, while the needle 2 is made of steel or titanium.
- Z -JpE, with E: Young's modulus of the material, in Pa.
- Z is of the order of 40,000,000
- for tungsten Z is of the order of 88 000 000
- for the titanium Z is of the order of 22 000 000.
- the more the impedance of the weight is greater than that of the needle, the more the movement of the bar will be transmitted preferentially to the needle, which increases the efficiency of the system.
- a continuous signal and a periodic signal are applied to the actuator during the duration of the injection, substantially at the chosen excitation frequency. For this, it feeds, by means not shown, the coil 31 with a current comprising the continuous signal and the periodic signal.
- the bar 30 elongates on average as a function of the intensity of the continuous signal, and periodically at the excitation frequency. Given the different linear impedances, the bar 30 bears against the weight 34 and sets The induced movement of the head 20 of the needle is for example an average displacement of 20 to 30 microns and oscillations around this average position of the order of 10 to 20 microns.
- the actuator can be made with a bar made of piezoelectric material.
