Definitions

  • the invention relates to a device for injecting fuel into the combustion chamber of an internal combustion engine having at least one injector, which includes a high-pressure accumulator integrated in the injector body, an injection nozzle which comprises an axially displaceable nozzle needle, which is surrounded by a nozzle chamber, a high-pressure accumulator with the injection nozzle connecting high-pressure bore and a parallel to the high-pressure bore resonator bore comprises, which communicates with the injection nozzle and is connected via a resonator in the high-pressure accumulator.
  • Injection injectors of this type are used in modular common rail systems, which are characterized in that a part of the existing storage volume in the system is present in the injector itself.
  • Modular common-rail systems are used in particularly large engines, in which the individual injectors may be mounted at a considerable distance from each other.
  • the sole use of a common rail for all injectors is not useful in such engines, as it would come to a massive slump in injection pressure due to the long lines during injection, so with prolonged injection duration, the injection rate would noticeably break.
  • it is therefore intended to arrange a high-pressure accumulator inside each injector.
  • Such a design is referred to as a modular structure, since each injector has its own high-pressure accumulator and thus can be used as a stand-alone module.
  • a high-pressure accumulator Under a high-pressure accumulator is not an ordinary line to understand, but it is at a High-pressure accumulator to a pressure-resistant vessel with an inlet and outlet, whose diameter is significantly increased compared to the high pressure lines, so that from the high-pressure accumulator a certain amount of injection can be delivered without causing an immediate pressure drop.
  • WO 2007/143768 A1 One way of reducing pressure pulsations is the WO 2007/143768 A1 can be seen, wherein a parallel to the high-pressure line between the injection nozzle and high-pressure accumulator switched resonator is provided, the high-pressure accumulator side has a resonator.
  • the resonator throttle is preferably arranged at the inlet of the resonator line into the high-pressure accumulator.
  • said resonator system is able to accelerate the decay of the pressure oscillations, the first pressure peak which occurs immediately upon closing of the injection nozzle can not be lowered thereby.
  • the invention therefore aims to lower as effectively as possible the first pressure peak occurring directly upon closing of the injection nozzle.
  • the invention essentially provides, proceeding from a device of the type initially mentioned, that the high-pressure bore comprises a first section adjoining the high-pressure accumulator and a second section opening into the injector, wherein the first section has a larger flow cross-section than the second section.
  • first and second portions directly adjoin one another.
  • the transition from the larger flow cross section of the first section to the smaller flow cross section of the second section can take place here continuously or stepwise.
  • the edge formed at the transition is preferably rounded.
  • both the first and the second section has a circular flow cross-section.
  • the first section of the high-pressure bore formed with a larger flow cross-section is formed as long as possible and thus brought as close as possible to the injection nozzle.
  • a preferred development in this context provides that the length of the first section corresponds to at least twice, preferably at least three times, the length of the second section.
  • An optimization of the effect achieved by the construction according to the invention can also be achieved by selecting the flow cross section of the first section as large as possible in relation to the flow cross section of the second section.
  • a preferred embodiment provides that the flow cross section of the first section corresponds to at least 1.5 times, preferably at least twice, preferably at least three times, more preferably at least four times, the flow cross section of the second section.
  • the inventive design is particularly advantageous for injectors to bear, in which the nozzle needle for controlling its opening and closing movement of the prevailing in a fuel-pressurized control chamber pressure in the axial direction can be acted upon, wherein the control chamber with an inlet throttle having inlet channel and a drain passage having flow channel is in communication and at least one inlet or outlet channel opening or closing control valve is provided with which the pressure in the control chamber is controlled, that the inlet throttle and the outlet throttle are formed in a throttle plate that the control valve in a valve plate is formed and that the high-pressure bore and the resonator bore to pass through the valve plate and the throttle plate.
  • the injector is usually designed such that an injector and / or holding body accommodating the high-pressure accumulator, the valve plate, the throttle plate and the injection nozzle are held together by a nozzle retaining nut.
  • the high-pressure bore and the resonator bore extend through the holding body, the valve plate and the throttle plate and thereby connect the high-pressure accumulator with the injection nozzle.
  • the section of the high-pressure bore passing through the throttle plate and the valve plate it is particularly advantageous in the context of the invention for the section of the high-pressure bore passing through the throttle plate and the valve plate to form the second section thereof or a part of the second section.
  • the flow cross-section is limited by design, since the resonator bore and the high-pressure bore on the valve assembly and the drain and possibly inlet throttle must be passed.
  • the first section of the high-pressure bore is preferably formed in a holding body. which is arranged between the high-pressure accumulator and the valve plate.
  • the transition from the first section into the second section of the high-pressure bore can be arranged, for example, at the transition of the holding body to the valve plate.
  • a preferred development provides that the transition from the first section to the second section of the high-pressure bore is arranged in the holding body. At the transition from the holding body in the valve plate in this case, only the smaller cross section of the second section is sealed.
  • the resonator throttle is arranged at the inlet of the resonator bore in the high-pressure accumulator.
  • the length of the resonator bore is preferably matched to the length of the high-pressure bore so that the pressure oscillations induced by the injector are mutually weakened or extinguished.
  • the length of the resonator bore between the injection nozzle and the resonator throttle and the length of the high-pressure line between the injection nozzle and the inlet of the high-pressure bore into the pressure accumulator are each preferably an integer multiple of the wavelength of the pressure oscillation induced by the injection nozzle.
  • the length of the resonator bore between the nozzle front chamber and the resonator throttle preferably corresponds substantially to the length of the high-pressure line between the nozzle front chamber and the inlet of the high-pressure bore into the pressure accumulator.
  • FIG.1 schematically a cross section of an equipped with a high-pressure accumulator injector according to the prior art
  • Fig.2 a schematic representation of the course of the flow cross-section of the high-pressure line between the high-pressure accumulator and injector.
  • an injector 1 having an injector 2, a throttle plate 3, a valve plate 4, a holding body 5 and a high-pressure accumulator 6, wherein a screwed to the holding body 5 nozzle retaining nut 7, the injection nozzle 2, the throttle plate 3 and the valve plate 4 together.
  • the solenoid valve 13 is closed, so that high-pressure fuel from the high-pressure accumulator 6 via the high-pressure line 8, the cross-connection 9 and the inlet throttle 10 flows into the control chamber 11 of the injection nozzle 2, the outflow from the control chamber 11 via the outlet throttle 12 but at the valve seat of the solenoid valve 13 is blocked.
  • the voltage applied in the control chamber 11 system pressure presses together with the force of the nozzle spring 14, the nozzle needle 15 in the nozzle needle seat 16, so that the injection holes 17 are closed. If the solenoid valve 13 is actuated, it releases the flow through the solenoid valve seat, and fuel flows from the control chamber 11 through the outlet throttle 12, the solenoid valve armature chamber and the low-pressure bore 18 back into the fuel tank, not shown. It turns through the flow cross sections of inlet throttle 10 and outlet throttle 12 defined equilibrium pressure in the control chamber 11, which is so low that the voltage applied in the nozzle chamber 19 system pressure is able to open the nozzle body longitudinally displaceable guided nozzle needle 15 so that the injection holes 17 are released and an injection takes place.
  • a resonator is used. This consists of a resonator 20, which has the same length and the same diameter as the high-pressure line 8, and a resonator 21, which is attached to the memory-side end of the resonator 20 and connects them to the memory 6.
  • the solenoid valve 13 When closing the solenoid valve 13, the pressure pulse generated at the nozzle seat 16 is propagated via the nozzle chamber 19 into the high-pressure line 8 and the resonator line 20.
  • FIG. 2 shows a highly schematic representation of the injector 1, wherein the in Fig. 1 Functional components described in more detail, namely the memory 6, the holding body 5, the valve plate 4, the throttle plate 3 and the injection nozzle 2 are only outlined, without their individual components, as they are based on Fig. 1 described individually.
  • Fig. 1 Functional components described in more detail, namely the memory 6, the holding body 5, the valve plate 4, the throttle plate 3 and the injection nozzle 2 are only outlined, without their individual components, as they are based on Fig. 1 described individually.
  • the high-pressure bore 8 which connects the high-pressure accumulator 6 with the injection nozzle 2 in a first portion 8 'has a larger diameter compared to the prior art, namely a significantly larger diameter than in a second portion 8 "
