Definitions
- the invention relates to a fuel delivery device for supplying an internal combustion engine of a motor vehicle with fuel from a fuel tank, with an electric motor driven fuel pump arranged in the fuel tank, with a supply line connected to the fuel pump and leading to the internal combustion engine and with a pressure sensor for determining the fuel supply Pressure of the pumped fuel to the internal combustion engine.
- Such fuel delivery devices having a pressure sensor deliver fuel depending on the needs of the internal combustion engine and are known in the art.
- the fuel pump generates a planned pressure and is controlled by an electronic control unit according to the values of the pressure sensor.
- the pressure sensor is arranged on an injection strip of the internal combustion engine. In this way, the pressure sensor allows the accurate detection of the pressure generated by the fuel pump on the internal combustion engine.
- a disadvantage of the known fuel delivery device is that the pressure sensor is exposed to the internal combustion engine strong vibrations and very high temperatures. The temperatures at the fuel rail of the engine often be 110 0 C. Therefore, the present invention Kraftstoffför ⁇ der adopted requires a very temperature-resistant and vibration-onsbe responsiblen and thus expensive pressure sensor.
- the invention is based on the problem, a fuel ⁇ conveyor device of the type mentioned in such a way that it is particularly inexpensive to manufacture.
- This problem is inventively achieved in that the pressure sensor is connected to a remote from the engine section of the flow line.
- the pressure sensor is disposed away from the internal combustion engine. Therefore, vibrations of the engine are not transmitted to the pressure sensor. Furthermore, high, generated by the internal combustion engine temperatures are not transmitted to the pressure sensor thanks to the invention.
- the pressure sensor is therefore loaded only with the maximum temperature of 60 ° of the fuel in the supply line be ⁇ . This makes it possible to use a particularly cost-effective pressure sensor.
- the fuel delivery device according to the invention is therefore particularly cost-effective.
- a possible escape of fuel vapors from the pressure sensor to the atmosphere can be according to an advantageous embodiment of the invention ⁇ easily avoided when the pressure sensor is connected to a guided within the fuel tank section of the feed line.
- the pressure sensor is also disposed within the fuel tank.
- the assembly of the fuel delivery device according to the invention is particularly simple if the pressure sensor is designed with the fuel pump as a structural unit.
- the fuel pump has a structural unit with a swirl pot, and a mounting opening of the motor ⁇ fuel tank closing flange.
- the pressure sensor can therefore be easily attached to one of these components and is mounted in the mounting of the fuel pump in Kraftstoffbe ⁇ container. Furthermore, can be through this design simply check the pressure sensor and demand control of the fuel pump outside of the fuel tank.
- the fuel delivery device according to the invention is particularly inexpensive to produce, if a fine filter, the pressure sensor, a pressure regulator and a check valve are designed as a structural unit.
- Contacting the pressure sensor is particularly simple and inexpensive if connection contacts for Verbin ⁇ extension of the pressure sensor with an electronic control system for on-demand control of the fuel pump in a one Montageöff ⁇ voltage of the fuel tank closing flange angeord ⁇ net are.
- the fuel delivery device designed constructively particularly simple if the pressure sensor striglie in a mounting opening of the fuel tank ⁇ sequent flange of the fuel pump is disposed.
- a fine filter often referred to as a life-time filter is arranged on the flange.
- the fuel delivery device according to the invention structurally particularly simple, when the pressure sensor is arranged in the flow direction between the fuel pump and the fine filter.
- a faulty measurement of the pressure sensor by a pressure loss caused by the fine filter and / or a check valve can easily be avoided according to another advantageous development of the invention if the pressure sensor is arranged immediately in front of a connection of the feed line leading away from the flange.
- the check valve When idling or when changing the load, the check valve may close when the fuel pump is in operation. Thanks to the invention, however, can also be idle or at Load change of the pressure generated by the fuel pump cushion measure when the pressure sensor is arranged in the flow direction in front of the check valve. A further advantage of this design is that a contamination of a fine filter arranged behind the check valve is also detected.
- FIG. 1 shows schematically a fuel delivery device according to the invention
- FIG. 3 shows schematically a partial area of a further embodiment of the fuel delivery device according to the invention with a pressure sensor arranged in front of a check valve
- Fig. 4 schematically shows a portion of a further embodiment of the invention Kraftstoffför- der adopted with a force within a ⁇ fuel tank pressure sensor arranged.
- the fuel delivery device 1 shows schematically a fuel delivery device 1 for conveying fuel from a fuel tank 2 to an internal combustion engine 3 of a motor vehicle.
- the fuel delivery device 1 has a fuel delivery unit 4 arranged inside the fuel tank 2 and a supply line 6 leading from the fuel delivery unit 4 to an injection rail 5 of the internal combustion engine 3.
- the fuel delivery unit 4 has a fuel pump 7 with an electric motor 8 and, arranged in a collecting provided fuel surge pot 9 Pumpenstu ⁇ fe 10.
- the surge chamber 9 is ⁇ container 2 is biased against the bottom of the fuel and is supported via a bracket 11 on a mounting opening 12 of the fuel tank 2-occlusive Flange 13 from.
- a pressure sensor 14 is arranged, which at a guided inside the fuel tank 2 portion of the flow line
- the pressure sensor 14 and the electric motor 8 of the fuel pump are connected via electrical lines 15, 16 with an electronic control unit 17.
- the control electronics 17 receives data of the pressure sensor 14 and controls in depen ⁇ dependence of the data of the pressure sensor 14, the fuel pump
- FIG 2 shows a portion of another embodiment of a portion of the fuel delivery device 1 of Figure 1, in which on the flange 13, a fine filter 18 is arranged.
- the pressure sensor 14 is connected to a guided within the fine filter 18 section of the flow line 6. Seen in the flow direction in front of the pressure sensor 14, a pressure regulator 19 or a safety valve is angeord ⁇ net. Between the fuel pump 7 and the fine filter 18, the supply line 6 also has a check valve 20th
- FIG. 3 shows a partial region of a further embodiment of the fuel delivery device 1, which differs from that of FIG. 1 only in that, as seen in the flow direction, the pressure sensor 14 is arranged in front of a check valve 21.
- FIG. 4 shows a further embodiment of a partial region of the fuel delivery device 1, which differs from that of FIG. 2 in that the pressure sensor 14 is arranged inside the fuel tank 2. Furthermore, the pressure sensor 14 is disposed in a between the fuel pump 7 and the front of the fine filter 18 arranged check valve 20 guided section of the flow line 6 connected. The guided to the control electronics 17 of Figure 1, electrical line 15 of the pressure sensor 14 has through the flange 13 guided connection contacts 22nd
