Definitions
- the invention relates to a conveyor with a
- Such conveyors are commonly used in today's vehicles and are therefore known.
- Today's fuel ⁇ pumps will be regulated depending on the demand for fuel to the engine in the future.
- the means for supply of the fuel pump with electrical current provides a current provided and an intended voltage clamping ⁇ optionally in a designated timing to the fuel pump.
- fuel pumps are subject to natural wear over their lifetime and can also become dirty. Thereby, the efficiency of the fuel pump, which con- sumption in an increase of the electrical Leis ⁇ decreases at the same hydraulic power output effect of the fuel pump.
- a particularly powerful fuel pump is used.
- a workersein ⁇ breakage of the internal combustion engine is avoided after wear or contamination of the fuel pump.
- the use of the particularly powerful fuel pump has the
- the invention is based on the problem, a conveying device ⁇ tion of the type mentioned in such a way that the use of a particularly powerful fuel pump can be avoided.
- This problem is solved according to the invention through a monitoring device for monitoring the power consumption of the fuel pump provided in hydraulic hoabga ⁇ be.
- This design enables a declining hydraulic can see performance under expected power consumption of the power ⁇ material pump over the life or of pollution record.
- the monitoring of power consumption of the motor fuel pump ⁇ thus ensures that the o- by wear of pollution reduced hydraulic power output is easily detected. Therefore, thanks to the invention, a Necessary to planned hydraulic power output ⁇ Liche fuel pump can be used and pollution when worn or Ver ⁇ clean or replace. Therefore, the conveyor according to the invention does not require a particularly powerful fuel pump.
- Another advantage of the conveyor device according to the invention is that the error can be limited in a particularly simple manner, for example in the event of a power breakdown of the internal combustion engine. Thanks to the monitoring device can be determined whether the cause of the power dip can be, for example, in the pollution and / or wear ⁇ the fuel pump.
- the conveying device designed to constructively particularly simple if the monitoring device in a versor the fuel pump with electrical current constricting ⁇ controller is arranged. Thereby also has the proper OF INVENTION ⁇ dung conveyor in a particularly clotting ⁇ ge number of components.
- the comparison between the power consumption and the delivered Hydraulic power easily determine when the controller is connected to a fuel-determining engine control unit of the internal combustion engine. Since the engine control unit in any case determines the demand of the internal combustion engine on fuel, it may be this need to which the force ⁇ fuel pump with electrical current serving controller berffenn Ü. The control unit then supplies the power ⁇ fuel pump with sufficient current and voltage, is covered to the required from the motor control unit needs.
- the comparison of the currently supplied current or the voltage with corresponding values of the new condition of the fuel pump is a measure of the actual wear of the fuel pump.
- the current wear or pollution of the force ⁇ fuel pump can, according to another advantageous Wei ⁇ ter Struktur of the invention, in each operating state of the ⁇ fuel pump determine if the control unit to be conveyed a memory for a fuel pump characteristic of the power consumption of the fuel pump in response to the Requires fuel of the internal combustion engine.
- the determination of the actual wear of the fuel pump requires according to another advantageous development of the invention has a particularly low structural expense when the control unit for determining the deviation of the required to be conveyed need for fuel hoauf ⁇ the fuel pump acquisition of the stored fuel ⁇ pump characteristic is trained.
- This design allows the detection of wear or contamination of the fuel pump before the need for fuel of the engine at full load by the fuel pump can no longer be met.
- the determined deviation of the current power consumption with the stored fuel pump characteristic curve is preferably stored and can be read out as part of an engine test.
- the assembly of the conveyor according to the invention is particularly simple if the control unit within the
- Conveyor preferably arranged in a flange to be inserted into the fuel tank.
- Fig. 1 shows schematically an inventive wisdomeinrich- tung for supplying an internal combustion engine ei ⁇ nes motor vehicle with fuel
- FIG. 2 shows a flow chart for monitoring a power consumption of a fuel pump of the inventive conveying device from FIG. 1.
- FIG. 1 schematically shows a conveyor 1 for supplying an internal combustion engine 2 of a motor vehicle with fuel from a fuel tank 3.
- the conveyor 1 has a arranged in a surge pot 4 force ⁇ fuel pump 5.
- the surge chamber 4 is biased against the bottom of the fuel tank.
- the fuel pump 5 för ⁇ changed the fuel from the surge chamber 4 via a feed ⁇ pipe 6 to the internal combustion engine 2.
- An engine control unit 7 determines in dependence on the operating state of the motor ⁇ vehicle the requirements of the internal combustion engine 2 of fuel and is provided with a fuel pump 5 with electric Power supplying control unit 8 connected.
- the control unit 8 has a memory 9 for a fuel pump characteristic.
- the fuel pump identification line indicates which Leis ⁇ con- sumption, the fuel pump 5 has to be conveyed in the amount of fuel. Since the to-promoting amount of force ⁇ material to the fuel demand of the internal combustion engine 2 ent ⁇ talking determined, the control unit 8 from the Kraftstoffpum ⁇ pen characteristic has the required tension, or provide the necessary ⁇ chen power for the fuel pump 5. Further, the controller 8 a monitoring device 10, is compared with whether the power consumption of the fuel pump 5 for För ⁇ tion of the required amount of fuel sufficient.
- the control unit 8 is also connected to a diagnostic display 11, which has, for example, a control lamp on a dashboard of the motor vehicle, and with a diagnostic socket 12 ⁇ connected.
- the diagnosis socket 12 can be used to read out the values of the monitoring device 10 and the state of wear or contamination state of the fuel pump 5 with a corresponding diagnostic device, not shown.
- control device 8 may be arranged in a flange 13 to be inserted into the fuel tank 3.
- FIG. 2 shows a flow chart for controlling and monitoring the fuel pump 5 of Figure 1.
- a first step Sl determines the engine control unit 7 may ⁇ Kraftstoffbe the internal combustion engine 2 and transmitted to the fuel ⁇ necessary to the control unit 8.
- the control unit 8 determines in a step S2 based on a stored or learned fuel pump characteristic and the fuel consumption, the power consumption of the fuel pump 5 and supplies the fuel ⁇ fuel pump 5 according to the intended power consumption with electrical current, the electrical voltage or current pulses.
- step S3 it is detected whether the demand of the internal combustion engine 2 is covered by fuel. If this is the case, the control unit 8 waits for a change in the requirements. 7.
- step S4 If the demand of the internal combustion engine 2 for fuel is not covered, the supply of the fuel pump 5 with electric current is increased in a step S4.
- monitoring device of the supervision 10 in a step S5 the deviation of the power consumption of the fuel pump 5 is determined by the fuel pump ⁇ characteristic. The determined deviation is a measure of the wear or contamination of the fuel pump 5.
- step S6 it is compared whether the deviation exceeds a prescribed threshold value. If this is the case, the diagnostic display 11 is activated and a message is stored, which can be read from the diagnostic socket 12 ⁇ . If the intended threshold value is not exceeded, the control unit 8 again waits for a change in the request of the engine control unit 7
