Definitions
- the invention is based on one Fuel injection device for an internal combustion engine according to the preamble of claim 1.
- Such a fuel injector is due to the DE 199 41 770 A1 known.
- This Fuel injector has a high pressure pump on, through the fuel under high pressure in at least a high-pressure accumulator is promoted.
- the High-pressure accumulators are on cylinders of the internal combustion engine arranged injectors connected.
- the injectors are included a common return line connected to one Low pressure accumulator forms. In the low pressure accumulator a minimum pressure to be maintained to the To ensure that the injectors are functional, especially if this is a control valve with a piezoelectric actuator and a hydraulic Have translation facility.
- the fuel injection device with the Features according to claim 1 has the advantage that a minimum pressure in the Low pressure accumulator can be maintained. Moreover can be targeted by diverting fuel from the High pressure accumulator by means of the pressure control valve Low pressure accumulator can be filled with fuel, whereby no additional feed pump is required. The one from the High-pressure accumulator fuel is warmed up so that the injectors quickly reach their operating temperature brought and their operation is stabilized.
- FIG. 1 shows a Fuel injection device for an internal combustion engine in a simplified schematic representation and Figure 2 a Injector of the fuel injector in an enlarged view Presentation.
- FIG 1 is a fuel injection device for a Internal combustion engine of a motor vehicle shown.
- the Internal combustion engine is preferably a self-igniting Internal combustion engine.
- the fuel injector has a high pressure pump 10 through which fuel is taken High pressure promoted in at least one high pressure accumulator 12 becomes.
- the high pressure pump 10 is mechanically by the Internal combustion engine driven and this has one or several pump elements by a drive in one Stroke movement are driven.
- the suction side of the High pressure pump 10 is fuel from a Fuel reservoir 14 by means of a feed pump 16 fed.
- the feed pump 16 can by the high pressure pump 10 or together with the high pressure pump 10 through the Internal combustion engine are driven.
- the Feed pump 16 also has its own drive, for example have an electric motor drive.
- injectors 20 With the high pressure accumulator 12 are on the cylinders Internal combustion engine arranged injectors 20 connected.
- injectors 20 each have Fuel injection valve 22 and a control valve 24.
- the control valve 24 has a piezoelectric actuator 26 on with an electronic control device 28 is connected and through this with an electrical Voltage is controlled.
- the piezoelectric actuator 26 changes depending on the voltage with which it is controlled , its length and thereby causes a hydraulic Translation device 30 a pressure change in one Actuator pressure chamber 32, through which a control valve member 34 Location changes.
- the fuel injection valve 22 has a Injection valve member 36, which by the im High pressure accumulator 12 prevailing pressure in one Opening direction is applied and that by the in one Control pressure chamber 38 prevailing pressure and possibly a closing spring 40 is acted upon in a closing direction is.
- the injection valve member 36 is at least one Injection opening 42 controlled.
- the control pressure chamber 38 is connected to the high pressure accumulator 12 and has one the control valve member 34 controlled connection to one Relief area on than the at least indirectly the Fuel tank 14 can serve. If the actuator 26 is not controlled and is therefore dead Pressure in the actuator pressure chamber 32 low, so that Control valve member 34 connects the control pressure chamber 38 to the relief area is interrupted.
- control pressure room 38 there is therefore high pressure as in the high-pressure accumulator 12 and the injector member 36 is closed in its Position held so that no fuel injection he follows. If the actuator 26 is controlled by the control device 28 is supplied with an electrical voltage, so increases the pressure in the actuator pressure chamber 32, so that the Control valve member 34 connects the control pressure chamber 38 releases to the relief area. It can from the Control pressure chamber 38 drain fuel so that the pressure decreases and the injection valve member 36 in Opening direction moves, so that fuel injection he follows.
- the hydraulic translation devices 30 of the Injectors 20 have a common low-pressure accumulator 50 connected.
- a Maintaining valve 52 maintain a predetermined pressure, for example between about 5 and 20 bar. If the specified pressure is exceeded, this opens Pressure holding valve 52 and lets fuel out of the Low-pressure accumulator 50 flow away, for example at least indirectly in the fuel tank 14 as Relief area. It can be provided that the at open control valve 24 by means of control valve member 34 de-fueled from the control pressure chamber 38 into the Low pressure accumulator 50 is directed as a relief area.
- each Transmission devices 30 non-return valve 54 arranged through which a filling of the Translation device 30 from the low pressure accumulator 50 is possible, but no fuel from the Translation device 30 in the low pressure accumulator 50 can drain off.
- the low pressure accumulator 50 ensured that the translation devices 30 with Are filled with fuel and thus the injectors 20 are functional.
- the fuel injector also has Pressure control valve 60, by means of which the pressure in High pressure accumulator 12 can be regulated.
- Pressure control valve 60 can fuel from the High-pressure accumulator 12 are shut down, reducing the pressure is reduced in the high pressure accumulator 12.
- the Pressure control valve 60 can be an electrically operated valve be formed, for example as a 2/2-way valve, the between a closed position in which no Fuel can flow out of the high pressure accumulator 12, and an open position in which fuel from the High-pressure accumulator 12 can flow, is switchable.
- the Pressure control valve 60 is controlled by control device 28 controlled by a by means of the pressure control valve 60 variable pressure can be set in the high pressure accumulator 12 can.
- the pressure control valve 60 has a cut-off connection 62 to a low pressure area, which the from the High-pressure accumulator 12 fuel is supplied. According to the invention it is provided that the control connection 62 of the pressure control valve 60 with the low pressure accumulator 50 is connectable as a low pressure area.
- a switching valve 64 is arranged through which the Discharge connection 62 optionally with the low pressure accumulator 50 or with a return 66 in the Fuel reservoir 14 as a relief area is connectable.
- the switching valve 64 can for example are switched depending on the temperature, such that at under a limit temperature lying fuel temperature the Discharge connection 62 with the low pressure accumulator 50 is connected and if it is above the limit temperature Fuel temperature control connection 62 with the Return 66 to the fuel reservoir 14 is connected.
- the changeover valve 64 can be in with the fuel in Have contact standing switching element 68, which depends from the fuel temperature changes shape and thereby the switching causes.
- the switching element 68 can consist of bimetal, for example, due to the different expansion coefficients of two different metals when the temperature changes Shape change results.
