Definitions
- the invention relates to a fuel injection device according to the preamble of patent claim 1.
- the fuel injection device according to the invention can be designed both stroke-controlled and pressure-controlled.
- a stroke-controlled fuel injection device is understood to mean that the opening and closing of the injection opening takes place with the aid of a displaceable valve member, due to the hydraulic interaction of the fuel pressures in a nozzle chamber and in a control chamber. A pressure drop within the control chamber causes the valve member to lift.
- the valve member can be deflected by an actuator (actuator, actuator).
- a pressure-controlled fuel injection device In a pressure-controlled fuel injection device according to the invention, the pressure prevailing in the nozzle chamber of an injector moves the valve member against the action of a closing force (spring), so that the Injection opening for an injection of the fuel from the nozzle chamber into the cylinder is released.
- the pressure at which fuel exits the nozzle chamber into a cylinder of an internal combustion engine is referred to as the injection pressure, while a system pressure is understood to mean the pressure at which fuel is available or is stored within the fuel injection device.
- a stroke-controlled injection has become known, for example, from DE 196 19 523 A1.
- the achievable injection pressure is limited to approx. 1600 to 1800 bar by the pressure storage space (rail) and the high pressure pump.
- a pressure booster unit is possible, as is known, for example, from US Pat. No. 5,143,291 or US Pat. No. 5,522,545.
- the disadvantage of these pressure-boosted systems lies in the lack of flexibility in the injection and poor quantity tolerance when metering small amounts of fuel.
- a pressure booster unit arranged in the injector is known from EP 0 691 471 A1.
- a bypass line for a pressure injection and a pressure chamber of the pressure translation unit are in series, so that the bypass line is only continuous as long as a displaceable piston of the pressure translation unit is not moved and is completely retracted.
- a fuel injection device is proposed.
- a hydraulic pressure booster unit is assigned to each injector of a common rail system, which both increases the maximum injection pressure to high pressures, e.g. greater than 1800 bar, as well as the provision of a second injection pressure.
- the bypass line leads at the end of the pressure chamber of the pressure translation unit into the supply line to the nozzle space or into the supply line from the pressure translation unit to the nozzle space.
- Fuel of lower pressure can be injected independently of the position of the pressure medium of the pressure booster unit. Due to the pressure translation unit, the pressure storage space and the injector are subjected to a lower static pressure (rail pressure) and thus have a longer service life.
- the high pressure pump is also less stressed. There is the possibility of a meterable pre-injection with low tolerances due to low (untranslated) injection pressure. By switching between the injection pressures, flexible post-injection or multiple post-injections can be implemented at high or low injection pressures.
- a quantity-controlled fuel pump 2 delivers fuel 3 from a storage tank 4 via a delivery line 5 into a central pressure storage chamber 6 (common rail), of which several pressure lines correspond to the number of individual cylinders 7 to the individual injectors 8 (injection device) projecting into the combustion chamber of the internal combustion engine to be supplied. 1 only one of the injectors 8 is shown.
- a first system pressure is generated and stored in the pressure storage space 6. This first system pressure is used for pre-injection and if necessary and post-injection (HC enrichment for exhaust gas aftertreatment or soot reduction) as well as for displaying an injection course with a plateau (boat injection).
- each injector 8 is assigned a local pressure translation unit 9, which is located within an injector 8.
- the pressure ratio unit 9 comprises a valve unit for pressure ratio control (3/2-way valve) 10, a check valve 11 and a pressure medium 12 in the form of a displaceable piston element.
- the pressure medium 12 can be connected at one end to the pressure line 7 with the aid of the valve unit 10, so that the pressure medium 12 can be pressurized at one end.
- a differential space 12 ' is relieved of pressure by means of a leakage line 13, so that the pressure medium 12 can be displaced to reduce the volume of a pressure chamber 14.
- the pressure medium 12 is moved in the compression direction, so that the fuel located in the pressure chamber 14 compresses and is supplied to a control chamber 15 and a nozzle chamber 16.
- the check valve 11 prevents the backflow of compressed fuel into the pressure storage space 6.
- a suitable area ratio in a primary chamber 14 ' and the pressure chamber 14 By means of a suitable area ratio in a primary chamber 14 ' and the pressure chamber 14, a second higher pressure can be generated. If the primary chamber 14 'is connected to the leakage line 13 with the aid of the valve unit 10, the pressure medium 12 is reset and the pressure chamber 14 is refilled. Due to the pressure conditions in the pressure chamber 14 and the primary chamber 14', the check valve 11 opens, so that the Pressure chamber 14 is under rail pressure (pressure of the pressure storage chamber 6) and the pressure medium 12 is hydraulically returned to its starting position.
- one or more springs can be arranged in rooms 12, 14 and 14 ' .
- a second system pressure can thus be generated by means of the pressure translation.
- the injection takes place via a fuel metering with the aid of a piston-shaped valve member 18, which is axially displaceable in a guide bore and has a conical valve sealing surface 19 at one end, with which it cooperates with a valve seat surface on the injector housing of the injector unit 8.
- Injection openings are provided on the valve seat surface of the injector housing.
- a pressure surface pointing in the opening direction of the valve member 18 is exposed to the pressure prevailing there, which is supplied to the nozzle space 16 via a pressure line 20.
- a pressure piece 22 also acts on the valve member 18, which delimits the control chamber 15 with its end face 23 facing away from the valve sealing surface 19.
- the control chamber 15 has an inlet with a first throttle 24 and an outlet to a pressure relief line 25 with a second throttle 26, which is controlled by a 2/2-way valve 27.
- the nozzle chamber 16 continues through an annular gap between the valve member 18 and the guide bore up to the valve seat surface of the injector housing.
- the pressure piece 22 is pressurized in the closing direction by the pressure in the control chamber 15.
- Fuel under the first or second system pressure constantly fills the nozzle chamber 16 and the control chamber 15.
- the pressure in the control chamber 15 can be reduced, so that the opening direction is subsequently increased the valve member 18 pressure force acting in the nozzle chamber 16 exceeds the pressure force acting on the valve member 18 in the closing direction.
- the valve sealing surface 19 lifts off the valve seat surface and fuel is injected.
- the pressure relief process of the control chamber 15 and thus the stroke control of the valve member 18 can be influenced via the dimensioning of the throttle 24 and the throttle 26.
- the end of the injection is initiated by renewed actuation (closing) of the 2/2-way valve 27, which decouples the control chamber 15 from the leakage line 13 again, so that a pressure builds up again in the control chamber 15, which pushes the pressure piece 22 in the closing direction can move.
- the valve units are operated by electromagnets for opening or closing or switching.
- the electromagnets are controlled by a control unit, which can monitor and process various operating parameters (engine speed, ...) of the internal combustion engine to be supplied.
- a control unit which can monitor and process various operating parameters (engine speed, %) of the internal combustion engine to be supplied.
- piezo position elements actuator, actuator
- actuator can also be used, which have a necessary temperature compensation and possibly a required force or displacement translation.
- the fuel injection device 1 has the pressure translation unit 9 arranged between the pressure storage space 6 and the nozzle space 16, the pressure chamber 14 of which is connected to the nozzle space 16 via the pressure line 20. Furthermore, the bypass line 28 connected to the pressure storage space 6 is provided. The bypass line 28 is connected directly to the pressure line 20. The bypass line 28 can be used for an injection with rail pressure and is arranged parallel to the pressure chamber 14, so that the bypass line 28 is continuous regardless of the movement and position of the displaceable pressure medium 12 of the pressure translation unit 9. The flexibility of the injection is increased.
- the pressure transmission unit 9 is arranged outside the injector 8 when the fuel injection device 1 is modified. This can be anywhere between the pressure storage space 6 and the injector 8. The size of the injector 8 is reduced. It is possible to integrate the pressure translation unit 9 with the associated valve arrangement and the pressure storage space 6 in one component.
- the valve arrangement can also be arranged outside the pressure booster unit 9.
- a fuel injection device 50 according to FIG. 3 has a pressure storage space 51 for fuel with a first system pressure.
- a higher system pressure is made possible by a pressure translation unit 52, which can be switched on with the aid of a valve unit 59.
- the pressure-controlled fuel metering takes place via a valve unit 55, e.g. a 3/2-way valve.
- a valve member 56 can be moved against the force of a valve spring 57 if the pressure applied to pressure surfaces 58 exceeds the spring force of the valve spring 57.
- the 3/2-way valves 55 and 59 are located within an injector 60.
- FIG. 4 shows a fuel injection device 61 similar to FIG. 3, the valve units for fuel metering 62 (3/2-way valve) and for pressure ratio control 63 (3/2-way valve) are arranged outside the injector 64.
- the Fuel injection device 61 it is also possible to arrange the two valves separately from one another.
- a simplified and loss-optimized control of a pressure transmission unit 70 results from FIG. 5.
- the pressure in the differential space 71 formed by a transition from a larger to a smaller piston cross section is used.
- This differential space becomes a pressure translation unit with a supply pressure
- This type of control can be used to reset the pressure transmission unit 70 and to refill a pressure chamber
- a throttle 75 and a simple 2/2-way valve 76 can be used to control the pressure booster unit 70 instead of a complex 3/2-way valve.
- the throttle 75 connects the differential space 71 with fuel under supply pressure from a pressure storage space 77.
- the 2/2-way valve connects the differential space 71 to a leakage line 78.
- the throttle 75 should be designed as small as possible, but still so large that the piston 72 returns to its starting position between the injection cycles.
- a guide leakage of the piston 72 can also be used as a throttle.
- the throttle can also be integrated in the piston.
- the injector is under the pressure of the pressure storage space 77.
- the pressure translation unit is in the starting position. Injection with rail pressure can now take place through valve 79. If an injection with a higher pressure is desired, the 2/2-way valve 76 is activated (opened) and thus a pressure increase is achieved.
- a 3/2-way valve can also be used to control the pressure in the differential chamber.
- Fig. 6 shows the control via a 3/2-way valve in a stroke-controlled Injection system.
- 7 shows the control via a 3/2-way valve in a pressure-controlled injection system.
- an injection pressure curve according to FIG. 8 results from the idle state (pressure translation unit deactivated and in the starting position).
- a pre-injection with low (rail) pressure is initiated via the bypass at the beginning of the injection cycle.
- the pilot injection is ended by closing valve 27 (see FIG. 1).
- Multiple pre-injections are also possible due to multiple peeling.
- the valve unit 10 arranged upstream of the pressure booster unit can be energized, so that an increased pressure in the nozzle chamber and control chamber corresponding to the gear ratio results in the injector.
- a main injection is now initiated by opening the valve 27 (dash-dotted line).
- the main injection is then ended again by closing the 2/2-way valve 27. If the pressure booster unit is activated at the same time as the valve 27, the result is an injection starting at the rail pressure level with a ramp-like rising edge up to the translated pressure (in the Figure 8 not shown). If the connection of the pressure translation unit is further delayed, injection is first carried out with rail pressure and, by switching on the pressure translation unit, a boot-shaped injection process results when the pressure translation unit is activated. The length of the high pressure component depends on the activation time of the pressure booster.
- the main injection is ended by closing the valve 27. If the pressure transmission unit is deactivated before the valve 27 is closed, the injection pressure ramps down to the rail pressure level, as is known from pressure-controlled systems. With post-injection, you can choose between a high and a low injection pressure level. A post-injection at high pressure to reduce soot or a post-injection at low injection pressure for exhaust gas aftertreatment can take place at a close distance after the main injection.
- an injection pressure curve according to FIG. 9 results from the idle state (pressure translation unit deactivated and in the starting position).
- a pre-injection with low rail pressure is initiated via the bypass at the beginning of the injection cycle.
- Multiple pre-injections are also possible due to multiple peeling.
- the rise in pressure in the nozzle chamber results in a ramp-shaped injection pressure curve in all subregions of the injection.
- the valve unit 59 arranged in front of the pressure booster unit to be energized simultaneously with the valve 55, so that there is a ramp-shaped course of the injection pressure up to the translated maximum pressure (dash-dotted line).
- the main injection is then ended again by closing the valve 55.
- connection of the pressure transmission unit is delayed, injection is first carried out with rail pressure, and a boot-shaped injection curve results from the connection of the pressure transmission unit.
- the length of the high pressure component depends on the activation time of the pressure booster.
- the main injection is ended by closing the valve 55, as a result of which the injection pressure in turn decays in a ramp-like manner by relieving the nozzle space to the leakage pressure level, and the injection is ended.
- post-injection you can choose between a high and a low injection pressure level.
- a post-injection at high pressure to reduce soot or a post-injection at low injection pressure for exhaust gas aftertreatment can take place at a close distance after the main injection.
