Definitions
- the invention relates to a fuel system for an internal combustion engine according to the preamble of claim 1.
- DE 10 2007 000 878 A1 describes a fuel system for a
- a decoupling of the high-pressure conveyor which is technically complicated, can be avoided, so the high-pressure conveyor can always "run along”. This is particularly advantageous if the high-pressure conveyor is mechanically driven, for example, by a camshaft of the internal combustion engine.
- a constantly moving high-pressure conveyor also has the advantage that there is always a high pressure downstream of the high-pressure conveyor available, so that immediately with a corresponding change of operating mode
- Fuel can be injected at high pressure, and so that the
- Hocfhdruck injectors permanently on the high-pressure rail can be acted upon with a certain pressure, whereby for so-called.
- Hold down force can be selected.
- the drive region comprises a recess in a housing in which a drive shaft and / or at least one conveying element, in particular a delivery piston are arranged / is.
- a drive region is particularly reliably cooled and lubricated by being flowed through or flushed through by the low-pressure fuel. It is also advantageous if the high-pressure conveyor a
- Quantity control valve includes. With such, for example, a
- Inlet valve of the high-pressure conveyor if this is a piston pump, forcibly be brought into the open position. Over the length of the period during which the inlet valve is open during a delivery stroke of the high pressure conveyor, the amount of fuel to be delivered can be adjusted. Especially if the intake valve is constantly forced to the open position, that is, when no fuel is conveyed to the high-pressure injector from the high-pressure conveyor, by the inventive measure the flushing of the drive portion of the high-pressure conveyor effective cooling and lubrication of the
- the low-pressure conveyor comprises an electrically driven fuel pump.
- an electrically driven fuel pump can be arranged, for example, directly in the fuel tank of the fuel system, which allows a particularly efficient operation.
- a typical system pressure that may be provided by the low pressure conveyor is 0.05 to 0.74 MPa, in other cases also about 1.00 MPa.
- Fuel system is characterized by the fact that the capacity of the electric fuel pump is variable. Not only can this react to different fuel requirements of the internal combustion engine, but also to a different lubrication and cooling requirement of the drive range of the high-pressure conveyor. As a result, fuel is saved because an unnecessarily high flow rate of the electric fuel pump is avoided.
- a low pressure rail Fluidically between the drive region of the high pressure conveyor and the low pressure injector, a low pressure rail may be arranged.
- a plurality of low-pressure injection devices can then be connected to such, for example, the fuel, for example, into corresponding intake pipes of respective cylinders of the internal combustion engine
- Such a low-pressure rail creates a buffer for the fuel, are equalized by the pressure pulsations.
- a high-pressure rail fluidically between the delivery area of the high-pressure conveyor and the high-pressure Injection device is arranged a high-pressure rail.
- a plurality of high pressure injectors may be connected to the high pressure rail, injecting the fuel, for example, directly into respective combustion chambers associated therewith.
- the fuel system is designed for a CNG, LPG and / or MPI operation of the internal combustion engine.
- CNG means “compressed natural gas”, thus allowing operation of the internal combustion engine with natural gas.
- LPG means “Liquid Pertol Gas”, so the internal combustion engine can then be operated with special LPG.
- MPI means “Multipoint Injection” and stands for the fact that the fuel in different places of the
- Internal combustion engine is injected, for example in the intake manifold, directly into the combustion chamber, or simultaneously both in the intake manifold and in the combustion chamber.
- a fuel system for an internal combustion engine carries in Figure 1 as a whole the reference numeral 10. It comprises a fuel tank 12, in which a
- Tank installation unit 14 is arranged. This in turn comprises a low-pressure conveying device in the form of an electric fuel pump 16.
- the low-pressure conveyor 16 conveys the fuel into a low-pressure fuel line 18, in which a filter 20 is arranged. Downstream of the filter 20, a return line 22 returns to the electric fuel pump 16. In the return line 22, for example, a pressure regulating or pressure relief valve may be arranged, which adjusts the pressure in the low-pressure fuel line 18 to a certain pressure. This valve is not shown.
- the low-pressure fuel line 18 leads to a high-pressure conveyor 24 in the form of a piston pump mechanically driven by the internal combustion engine.
- the high pressure conveyor 24 includes a
- the drive region 26 in this case comprises a not shown recess in a not closer in Figure 1 shown housing the high-pressure conveyor 24, in which a
- Drive shaft and a conveying element for example, a delivery piston are arranged.
- the drive shaft is for example an eccentric shaft, which in turn is mechanically driven by the internal combustion engine.
- this drive shaft is mounted in the housing.
- the delivery area 28 comprises an inlet valve (also not shown in more detail in the figure), a delivery chamber and an outlet valve. About the intake valve, the fuel from the low-pressure fuel line 18 and the
- the operation of the fuel system 10 is controlled by an electronic control and regulating device 44.
- the fuel system 10 is controlled by an electronic control and regulating device 44.
- the electronic control and regulating device 44 For example, the
- Control and regulating device 44 connected via a power output stage 46 with the low-pressure conveyor 16, whereby the flow rate can be changed. Further controls the control and regulating device 44 in the drawing also not shown quantity control valve. This is, for example, an electromagnetic
- Actuator by which the inlet valve of the delivery area 28 of the high-pressure conveyor 24 can be forcibly kept open. Over the duration during which the inlet valve during a delivery cycle of the high-pressure conveyor 24 is forcibly opened, the
- Delivery of the high-pressure conveyor 24 can be adjusted. No fuel at all from the high-pressure conveyor 24 in the High pressure rail 34 are promoted, for example, the inlet valve is constantly forced to the open position.
- a pressure relief valve 48 is controlled by the control and regulating device 44, which can connect the high-pressure rail 34 via a return line 50 with the low-pressure fuel line 18. In this way, the pressure in the high-pressure rail 34 can be lowered.
- the controller 44 receives signals from various sensors, such as one
- Pressure sensor 52 which detects the pressure in the high-pressure rail 34
- a pressure sensor 54 which detects the pressure in the low-pressure rail 40.
- the fuel system 10 operates as follows: From the low-pressure conveyor 16, the fuel is conveyed into the low-pressure fuel line 18. From there it enters the drive region 26 of the high-pressure conveyor 24, whereby the moving parts located there
- the fuel passes firstly into the second low-pressure fuel line 38 and from there into the low-pressure rail 40, from where it is injected via the low-pressure injectors 42, for example, into intake pipes of respective cylinders of the internal combustion engine.
- the high-pressure conveyor 24 is conveyed from the high-pressure conveyor 24 into the high-pressure rail 34 and via the high-pressure injectors 36 directly into the cylinder of the fuel machine.
