It is provided a fuel supply line, via which the injector fuel is supplied. Upstream of the injector, a high-pressure accumulator is provided, which is also referred to as a so-called common rail, common rail. If the internal combustion engine has several injectors, these are preferably supplied with fuel from the common high-pressure accumulator. To promote fuel in the high pressure accumulator, a high pressure pump is provided. A pressure in the high-pressure accumulator is regulated by means of an intake throttle arranged upstream of the high-pressure pump.
- a quantity limiting valve is arranged between the high-pressure accumulator and the injector, which supplies an amount of fuel flowing from the high-pressure accumulator to the injector limited. If the injector malfunctions, so that too much fuel tends to flow into the combustion chamber, the flow control valve will respond, interrupting fluid communication between the high pressure accumulator and the defective injector.
- the invention is therefore based on the object, a method and a
- the object is achieved by providing a method with the steps of claim 1.
- the method is characterized in that the fuel supply line is vented downstream of the high pressure pump, wherein in the suction throttle during a venting operation, a passage cross section for the fuel is set, which is less than or equal to a predetermined limit passage cross section.

- Venting operation when starting the internal combustion engine is performed.
- the venting operation is performed at a first start of the internal combustion engine.
- the venting operation is performed after a maintenance or repair of the internal combustion engine.
- the bleeding operation is performed when the fuel supply pipe is vented downstream of the high-pressure accumulator.
- a Senstechniksmittel is provided, is determined by means of which, in particular when starting, whether the
- Fuel supply line is vented downstream of the high-pressure accumulator. If this is determined, the bleeding operation is performed when starting the internal combustion engine. On the other hand, if no ventilation of the fuel supply line is detected, the internal combustion engine is preferably started in a normal start-up operation. In this case, in the normal start-up operation preferably the passage cross-section of the suction throttle is set to a maximum value in order to quickly as possible
- Entlwillungs beautiful thus differs from the normal start-up operation precisely in that contrary to the conventional approach, as quickly as possible by maximizing the fuel delivery a predetermined pressure in the

- an algorithm is further preferably implemented, which makes it possible to perform the venting operation, in which the
- Passage cross section of the suction throttle is set smaller than or equal to the predetermined limit passage cross section.
- the engine control unit is preferably operatively connected to the suction throttle for driving.
- Bleeding operation is terminated as soon as the fuel supply line is vented.
- the venting operation is terminated by the fact that the suction throttle - preferably by the engine control unit - is controlled to control the pressure in the high-pressure accumulator. So it is to stop the venting operation, the control of the intake throttle changed, which is no longer on a

- predetermined limit passage cross-section is selected to 50%, preferably 25%, preferably 15%, preferably 10%, preferably 5%, preferably 2%, preferably 1% of a maximum passage cross-section of the suction throttle.
- Suction choke is preferably designed so that its passage cross-section between a minimum passage cross-section and a maximum
- Passage cross-section is gradual or preferably continuously variable.
- the predetermined and preferably in the engine control unit deposited boundary passage cross section is selected depending on a used in the internal combustion engine flow control valve. This procedure is based on the idea that different quantity-limiting valves respond at different values of a fuel flow flowing over them, so that preferably the limit passage cross-section is matched to a specifically installed quantity-limiting valve.
- the predetermined one is preferred
- Boundary passage cross-section matched to the specifically used suction throttle and a concrete used Mengenbegrenzungsventil, so that it is ensured that in the venting operation is not an impermissibly high flow over the
- Engine speed of the internal combustion engine during the bleeding operation at about 100 revolutions per minute (rpm) is maintained. This value is preferably below an idle speed of the internal combustion engine. As a result, the delivery rate of the high-pressure pump is additionally reduced, which is advantageous for the venting operation.
- a method is also preferred which is characterized in that a pressure is sensed downstream of the flow control valve.
- a pressure sensor is preferably downstream of the quantity limiting valve in the
- Engine control unit operatively connected so that it can evaluate the pressure detected by the pressure sensor and use it to control the internal combustion engine.

All features described in connection with the method are preferably individually or in combination with one another features of an embodiment of the
- Figure a schematic representation of an embodiment of a direct injection system of an internal combustion engine.
- the figure shows a schematic representation of a direct injection system 1 of an embodiment of an internal combustion engine.
- the direct injection system 1 has an injector 3 through which fuel 7 can be injected into a combustion chamber, not shown, of the internal combustion engine by means of a valve device 5 shown schematically.
- the injector 3 also includes an internal fuel reservoir 9.
- a fuel supply line 11 serves to deliver fuel from a
- a high-pressure accumulator 15 is arranged, from which the injector 3 is supplied with fuel.
- a quantity limiting valve 17 is arranged in the fuel supply line 11 in order to protect the internal combustion engine from an inadmissibly high amount of fuel, the over a defective injector 3 could be introduced into the combustion chamber.
- a high-pressure pump 19 For conveying fuel into the high-pressure accumulator 15, a high-pressure pump 19 is arranged in the fuel line 11 upstream thereof. Their delivery rate is controlled by a suction throttle 21 arranged upstream of the high-pressure pump 19, wherein in particular the pressure in the high-pressure accumulator 15 is regulated by means of the suction throttle 21.
- the suction throttle 21 is shown here schematically as separate from the high-pressure pump 19 valve device. However, it is quite possible that the suction throttle 21 is formed as part of the high pressure pump 19 or integrated into it.
- a passage area of the suction throttle 21 is between a minimum value and a maximum value
- the minimum value of the passage cross section corresponds to a closed position of the suction throttle 21, so that in this case no fuel can be conveyed via the suction throttle 21.
- a low-pressure pump 23 is provided, which is the promotion of fuel from the
- Reservoir 13 via a filter 25 to the suction throttle 21 is used.
- the quantity limiting valve 17 has a flow-limiting device 27 and a compensation volume 29 arranged downstream of it, wherein the compensation volume 29 preferably has a flow volume
- Throttle device 31 includes.
- the flow-limiting device 27 comprises in the illustrated embodiment a displaceable in a cylinder 33 piston 35 which is biased in the position indicated by A by a spring element 37.
- a fixed throttle 39 is schematically indicated that in the region of the piston 35, a predetermined passage cross-section is provided for fuel. It is possible that the fuel through a bore in the piston 35 - as indicated in the figure by the fixed throttle 39 - can flow through. In another embodiment, it is possible that the fuel may flow past the piston 35 laterally. Other embodiments, the function of the fixed throttle 39 to realize, are possible.
- the piston 35 is displaceable from its stop position shown at A via a middle position shown at B against the biasing force of the spring element 37 to a stop position shown at C.
- the quantity limiting valve 17 is arranged in a blocking position in this case, so that no more fuel can flow from the high-pressure accumulator 15 to the injector 3.
- the pressure in the high-pressure accumulator 15 is regulated by means of the suction throttle 21. If the valve device 5 of the injector 3 is closed, no fuel flows from the high-pressure accumulator 15 via the quantity limiting valve 17 to the injector 3. If an injection of fuel 7 into the combustion chamber assigned to the injector 3 is carried out by means of the injector 3, fuel 7 flows over the valve device 5 from, whereby at the same time results in a fuel flow from the high-pressure accumulator 15 to the injector 3 via the flow control valve 17.
- Fixed throttle 39 has decreased during the injection event and during the displacement of the piston 35 compared to the pressure level of the high-pressure accumulator 15. During pressure equalization, the piston 35 shifts back from the position B to the position A, in which it is urged by the spring element 37.

Because of the fixed throttle 39, not enough fuel per unit time can flow to the
- Fluid communication between the high-pressure accumulator 15 and the injector 3 is blocked. It can then no longer flow of fuel from the high-pressure accumulator 15, so that the compensating volume 29, possibly the internal memory 9 and the injector 3 idles into the combustion chamber. As a result, the pressure in the region of the injector 3 decreases, so that the piston 35 is permanently affected by the pressure difference between the high-pressure accumulator 15 on the one hand and the injector 3 on the other hand in the case of C.
- Lock position is held.
- the quantity limiting valve 17 is therefore permanently locked, and it can not be introduced inadmissible amount of fuel through the defective injector 3 in the combustion chamber.
- the internal combustion engine is protected from damage caused by an excessive amount of energy.
- the fuel supply line 11 in total or at least downstream of the
- the high-pressure pump 19 delivers fuel into the high-pressure accumulator 15 and from there via the fixed throttle 39 into the compensating volume 29 and to the injector 3.
- the passage cross section of the intake throttle 21 set at a normal start-up operation of the internal combustion engine to a maximum, so that a predetermined pressure in the high-pressure accumulator 15 sets as soon as possible.
- the fixed throttle 39 is a flow obstacle, above the piston 35, a pressure drops.
- the compensating volume 29 vented, so filled with a compressible medium, in particular air, the piston 35 moves due to the
- Fluid connection between the high-pressure accumulator 15 and the injector 3 permanently blocks. It is then no longer possible injection through the injector 3. This leads to a lack of power and / or to a non-circular engine running of the internal combustion engine. The internal combustion engine may then have to complete several times be shut down, and the fuel supply line 11 must be relaxed upstream of the flow control valve 17, because otherwise no
- the suction throttle 21 is driven so that it has only a passage cross-section which is less than or equal to a predetermined
- Boundary passage cross-section is.
- the limit passage cross-section is preferably smaller than a in the normal operation of the internal combustion engine typically of the
- Suction choke 21 assumed passage cross-section, and in particular smaller, preferably much smaller than the maximum passage cross-section, which is taken at a normal starting of the internal combustion engine. In this way, the amount of fuel delivered by the high-pressure pump 19 is limited so that the fuel supply line 11 upstream of the high-pressure pump 19 is slowly filled with fuel.
- Deaeration operation adjusted so that the funded by the high-pressure pump 19 amount of fuel until the end of the bleeding mode just corresponds to the flow rate flowing through the fixed throttle 39.
- the passage cross section of the suction throttle 21 in the venting operation is preferably selected so that the piston 35 is not, only very slowly, or at most only as quickly in the direction of his in C
- Fuel supply line 11 is completed before the piston 35 his
- High-pressure accumulator 15 are controlled via the suction throttle 21.
- the speed of the internal combustion engine is preferably during the
- Bleeding operation it is preferably increased to an idle speed
- the high-pressure pump 19 is preferably driven by the speed of the internal combustion engine, which is preferably reduced during the bleeding operation, the delivery of the high-pressure pump 19 is limited by the control of the suction throttle 21, which
