Definitions
- the invention relates to an apparatus and a method for operating a fuel delivery system.
- the invention further relates to a fuel delivery system, in particular for a motor vehicle.
- the electric pump is designed in such a system to provide a pressure of about 5 bar.
- the high pressure up to about 200 bar is realized by the attached to the engine, driven by the camshaft, pump.
- an active volume or pressure control valve must be provided, which regulates the pressure which is provided to the injection valves.
- the invention is characterized by a method and a corresponding device for operating a
- the fuel delivery system includes an electric pump disposed within a fuel tank.
- the electric pump is designed to deliver fuel from the fuel tank to a fuel storage.
- the speed of the electric pump is controlled or controlled in dependence on a predetermined value for a pressure in the fuel storage.
- the pump is for example a piston pump which has only passive inlet and outlet valves. On active volume or pressure control valves can be dispensed with, since the flow control is adjusted via the variable speed of the electric pump. Thus, only a single pump needs to be provided in the fuel delivery system that delivers the fuel from the fuel tank to the fuel storage. On a second pump, which is driven by the camshaft and is mounted for example on the internal combustion engine, can be omitted.
- the electric pump is disposed in the fuel tank from which it can deliver fuel. This makes a leak tolerable.
- the electric pump is in particular designed to provide a pressure of up to 200 bar.
- the electric pump is adapted to provide a pressure between 50 bar and 250 bar.
- the fuel pump is for example configured to provide a pressure in the fuel reservoir of more than 100 bar.
- the electropump which can provide high pressure, provides a low cost fuel delivery system because only a single pump is provided to deliver fuel from the tank and provide high pressure in the fuel storage. In addition, no flow valve is necessary. In addition, the drive of the electric pump can be easily cooled within the fuel tank.
- an actual pressure in the fuel tank is determined.
- a difference between the determined actual pressure and the predetermined value for the pressure is determined.
- the speed of the electric pump is regulated as a function of the difference determined.
- a pressure sensor is arranged in the fuel reservoir for determining the actual pressure in the fuel reservoir.
- the pressure sensor is coupled to the device for operating the fuel system.
- the desired predetermined value for the pressure is supplied more or less electrical energy, so that the speed of the electric pump and thus the flow rate of the electric pump changes.
- the actual pressure is simply adjusted to the predetermined value for the pressure.
- a current value for the electric pump is determined as a function of the predetermined pressure.
- the electric pump is charged with the determined current value and thereby the speed of the electric pump is controlled. So it is possible to dispense with the pressure sensor in the fuel tank. This is a cost effective fuel delivery system possible.
- a pure current control of the electric pump is possible because the applied current is proportional to the speed of the pump and the speed of the pump is in turn proportional to the pressure provided.
- the pressure provided by the electric pump is directly controllable.
- a value of the electrical current at the electric pump is determined.
- a value of the voltage at the electric pump is determined.
- An estimated value for the pressure in the fuel storage is determined as a function of the determined value of the current and the determined value of the voltage.
- the speed of the electric pump is regulated as a function of the estimated value determined. This makes it possible to dispense with the pressure sensor in the fuel storage. From the current and the voltage at the electric pump, the estimated value for the current actual pressure in the fuel storage is determined. From a difference between the estimated actual pressure and the predetermined value for the pressure, for example, the speed of the electric pump is controlled, so that the actual pressure at the predetermined value for the pressure equalizes.
- the fuel system has a pressure accumulator, which is in each case hydraulically coupled to the electric pump and the fuel accumulator and which is arranged hydraulically between the electric pump and the fuel accumulator.
- the pressure accumulator is arranged inside the fuel tank. The pressure accumulator is charged by the electric pump so that, for example, the pump only has to actively pump fuel when the pressure accumulator is empty or almost empty.
- the pump is always operable in full production during operation, but only for a fraction of the operating time of the engine.
- the accumulator stabilizes the pressure control for the fuel accumulator.
- a pressure reserve is available with frequent switching off and on of the internal combustion engine.
- the arrangement of the pressure accumulator within the fuel tank a simple construction of the pressure accumulator is possible because a principle-related leakage can be realized by the arrangement in the tank. The efficient operation that is possible in this way makes it possible, in particular, to reduce CO 2.

- the fuel storage 102 is hydraulically coupled to the electric pump 103.
- the fuel storage 102 is filled in operation by the electric pump 103 with fuel 111 from the fuel tank 101. From the fuel storage 102, the fuel is guided, for example, to injectors and injected by these into combustion chambers of an internal combustion engine. The fuel pressure required for the fuel storage 102 is provided by the electric pump 103.

- the device 109 sets a higher rotational speed of the electric pump 103.
- the electric pump 103 is supplied, for example, more electrical energy.
- the volume flow of the electric pump 103 and thereby the pressure in the fuel storage 102 increases.
- the rotational speed and thus the volume flow of the electric pump 103 are reduced when a lower pressure is specified in the fuel storage 102.
- the amount of fuel delivered by the electric pump 103 to the pressure accumulator 102 is adjusted via the rotational speed of the electric pump 103 and thus via the supplied electrical energy.
- a pressure sensor 110 is provided in the fuel reservoir 102.
- the pressure sensor 110 is set up to determine a current actual pressure of the fuel in the fuel storage 102.
- the pressure sensor 110 is coupled to the device 109.
- the pressure sensor 110 transmits the determined actual pressure to the device 109.
- the device 109 is set up to compare the determined actual actual pressure with the predetermined value for the pressure in the fuel storage 102. If the determined actual pressure in the fuel reservoir 102 deviates from the predetermined value for the pressure, in particular by more than a predetermined tolerance range, the device 109 adjusts the electric pump 103 accordingly. For example, a control signal is output by the device 109, which adjusts the rotational speed of the electric pump 103 as a function of the difference between the determined actual pressure and the predetermined value for the pressure.
- FIG. 2 shows a schematic representation of the fuel delivery system 100 of FIG. 1 according to further embodiments.

- the piston 107 is movably arranged in the storage body 108 and biased for example by means of a spring.
- Fuel which is conveyed by the electric pump 103, enters the pressure accumulator 106 and displaces the piston 107 relative to the accumulator body 108 against the spring force.
- a leakage of the pressure accumulator, in particular between the piston 107 and the storage body 108, is tolerable, since the pressure accumulator 106 is arranged in the fuel tank 101.

If the predetermined pressure for the fuel storage 102 is, for example, 100 bar, a corresponding control signal is output by the device 109, so that a current of 20 A is applied to the electric pump 103. Due to the applied current of 20 A, the speed of the electric pump 103 is controlled so that builds up in the fuel tank 102, a pressure of about 100 bar.
