Definitions

  • the invention relates to a starting system for engines with a common fuel injection rail.
  • the patent application US5839413 discloses a system that can reduce the starting time of an engine with a common rail.
  • the principle of this system is to communicate the common rail not only to a high pressure pump but also to a low pressure circuit with two calibrated check valves (a first low pressure and a second high pressure).
  • the low pressure circuit has a low pressure accumulator which makes it possible to maintain a stable pressure lower than that delivered when the high pressure pump is at full load.
  • the object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing a simple starting system comprising a redundant compression means easily integrable to adapt the existing engines to the technique "stop and start”.
  • the elastic means comprises a spring, a hollow plate fixed between said electromagnetic means and said storage means and the ball capable of plugging the hollow of said plate and secured to said spring allowing, according to the relative pressures between the accumulator means and said at least one storage means, the communication between the latter two.
  • the actuator means comprises, according to the invention, a first rod located substantially on the central axis of said tunnel formed by the coil, a plate fixed substantially perpendicular to an end of said first rod and a second rod which, in extension of the other end of the first rod, is in contact with said ball and has a diameter smaller than the hollow of said plate for following or initiating the movement of said ball.
  • the plate further comprises, advantageously according to the invention, at least one groove able to pass in its hollow fuel when said plate is against said electromagnetic means.
  • the supply means advantageously comprise a pump supplying fuel to said accumulator means and a non-return valve allowing a direction of circulation of the fuel only from the pump to the said accumulator means.
  • the starting system 1 mainly comprises a common rail 2, feed means 3, injection means 4 and a pressurized fuel storage device 5.
  • the power supply means 3 consist of a high pressure pump 6 of a pipe 7 and a non-return valve 8. This pump will compress and send fuel under pressure to the common rail 2 through the conduit 7
  • the check valve 8 mounted in the same duct, is used to prevent fuel back-up in the pump 6 when the fuel pressure is higher in the common rail 2 than at the outlet of said pump.
  • Injection means 4 in the example illustrated in FIG. figure 1 , Mainly comprise for each cylinder of said engine a pipe 9 and an injector 10.
  • the pipe 9 allows the injector 10 to be connected to the common rail 2 and thus to be fed with fuel under pressure. Indeed, each injector can operate only with a fuel under a predetermined minimum pressure. Thus for a four-cylinder engine, it will be necessary to use four sets of pipe 9 - injector 10.
  • the pressurized fuel storage device 5 is, in the same example illustrated, in direct communication with the common rail via a conduit 11.
  • said storage device comprises storage means 12 and opening means 13.
  • the storage means 12 mainly comprise an enclosure 14 and a sensor 15. This first can contain fuel at a pressure at least also that supplied by the high pressure pump 6.
  • the sensor 15 makes it possible to determine the pressure of the fuel at the same time. inside said enclosure.
  • the opening means 13 allow the communication between the enclosure 14 and the conduit 11.
  • These opening means comprise first elements with elastic properties 16 and second with electromagnetic properties 17, these two series of elements being mechanically linked.
  • Said first elements comprise a spring 18, a ball 19, a hollow spring seat 20 and a hollow ball seat 21.
  • the spring seat 20 is used not only to maintain the orientation of said spring but also thanks to its hollow to make communicating fuel between the opening means 13 and the storage means 12.
  • the spring 18 comprises at the end opposite to said spring seat the ball 19. This, according to the responses of the spring to the applied stresses, will print a translational movement able to open or close the hollow of the ball seat 21 and thus allow the fuel communication between the spring seat 20 and the duct 11.
  • Said second elements comprise control electrodes 22, a coil 23 and an actuator 24.
  • the electrodes 22 supply current in the coil 23 so as to induce a magnetic field capable of moving said actuator.
  • the spool 23 is mounted against the ball seat 21 so that its inner diameter is centered on the same point as that of said hollow of the ball seat 21.
  • the actuator 24 comprises a circular plate 25, a first rod 26 and a second rod 27.
  • the plate 25 has magnetic characteristics such that, during the passage of the current in the coil 23, it will be attracted to the latter.
  • the plate 25 has three grooves 28 equidistant from each other on the face vis-à-vis with said coil.
  • the first rod 26 is integral with said plate so that said rod is found substantially along the central axis of the inner surface of the coil 23. As an extension of the first rod 26 is fixed the second rod 27. This last is thinner than the first rod 26 but also that said ball seat recess so that it can pass through.
  • the second rod 27 is in permanent contact with the ball 19 which makes it possible to mechanically link the elastic elements 16 and the electromagnetic elements 17.
  • the actuator 24 will be moved away from the coil 23 or when the coil 23 receives current, the actuator 24 will dislodge the ball 19 from its seat 21.
  • the storage means 14 which is filled with fuel under low pressure, is not operational.
  • the sensor 15 detects it and does not allow the opening of the storage device during startup.
  • the engine is then started and through the distribution element, the high pressure pump 6 is started.
  • the inertia of the pump 6 does not immediately provide the minimum pressure necessary for the injectors 10. After this minimum pressure exceeded, the pump 6 will continue to increase the pressure in the common rail 2, fuel will then be present in the duct 11, around the plate 25 and in the hollow interior volume of the coil 23, moreover, the first injections are made.
  • the engine is then started.
  • the spring 18 calibrated according to this threshold pressure will allow the passage of fuel and thus allow the filling of the storage means 14. According to the relative pressure between the common rail 2 and the storage medium 14, the spring 18 will contract or relax so that, respectively, the fuel pressure contained in the storage means 14 increases or remains stable.
  • the driver decides to stop the engine, the high pressure pump 6 is stopped.
  • the pressure in the common rail 2 drops, the spring 18 will relax to press the ball 19 on its seat 21 and thus trap pressurized fuel in the storage means 14.
  • the engine is then stopped and the storage device 5, operational .
  • the sensor 15 detects that the pressure is sufficient and then allows the release of the fuel contained in the storage means 14 to the common rail 2. This is achieved by the activation of the coil 23.
  • the actuator is then be drawn against the coil 23 and thus push the ball 19 of its seat 21 through the rods 26 and 27.
  • the fuel contained in the storage means 14 is then released and will pass successively through the hollow of the spring seat 20, the hollow of the ball seat (around the rod 27), the inside diameter of the coil 23 (around the rod 26), the grooves 28 of the plate 25 and the duct 11.
  • the non-return valve 8 blocks the pipe 7 and thus makes it possible to keep the pressure, due to the release, constant in the common rail 2.
  • the pressure in the common rail 2 is then sufficient for a computer (not shown) of the engine to allow the operation of the injectors 10.
  • the high pressure pump 6 being set in motion from the engine distribution elements, the first injections will have an accelerating effect on the performance of the pump 6 which will therefore more quickly increase in pressure.
  • the non-return valve 8 of the pipe 7 will allow communication between said common rail and the pump 6 for the latter to take over from said storage device 5.
  • the coil 23 is then preferentially deactivated.
  • the storage means 14 is sized so that two cycles of injections can be performed before the high pressure pump provides a pressure greater than that of the common rail 2.
  • the spring 18 calibrated according to this threshold pressure will allow the passage of fuel and thus allow the filling of the storage means 14.
  • the storage device 5 cycle repeating as previously explained to allow said engine to acquire a start sufficiently short to adapt to the technique called "stop and go”.
  • the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art.
  • the location of the storage device may be different.
  • the movement of the plate 24 can be made more linear by stops accompanying the sliding of said actuator along the storage device 5.
  • the non-return valve 8 can be integrated with the high pressure pump 6.
  • the The system can operate without a pressure sensor 15 and release the pressure contained in the storage means 14 by means of a timer or other device.
