Definitions
- the invention relates to a fuel delivery system for an internal combustion engine of a motor vehicle with the features mentioned in the preamble of claim 1 and a method for operating the fuel delivery system with the in the preamble of Claim 3 mentioned features.
- Fuel delivery systems of the type mentioned above have at least one fuel pump on the fuel via a pressure line system from a tank Promotes internal combustion engine.
- a pressure regulator Fuel pump assigned or integrated into this.
- a disadvantage of such Fuel delivery system is that the fuel pump for a very large Operating area must be designed with regard to their capacity.
- Operating phases of the internal combustion engine can, however, the delivery rate such fuel pump may not be sufficient. For example, the start phase the internal combustion engine due to air pockets in the fuel as a result of insufficiently low delivery capacity can be interrupted.
- the invention is therefore based on the object of a fuel delivery system and a To provide procedures for operating the fuel delivery system that the Disadvantages of the prior art are overcome and the delivery rate in selected Operating phases of the internal combustion engine ensures.
- this object is achieved by a fuel delivery system with the Claim 1 mentioned features and a method for operating the Fuel delivery system with the features mentioned in claim 3 solved.
- the fuel delivery system 10 includes a fuel pump 12 that has a Pressure line system 14 is connected to a tank 16. Because of Clarity is more appropriate to the representation of the internal combustion engine Adjustment means for the fuel pump 12, such as a pressure regulator, are dispensed with been.
- an additional pump 18 is integrated, which is in a bypass 20 of the pressure line system 14 is housed and parallel to one Check valve 22 is located.
- the additional pump 18 blocks the bypass 20, and the promotion can only be carried out by the check valve 22 respectively. A backflow of the fuel through the bypass 20 is thus prevented.
- the fuel pump 12 and the auxiliary pump 18 are a control unit 24 assigned that directly or via known data lines Actuating means is connected to the auxiliary pump 18 and the fuel pump 12. About the Control unit 24, a delivery rate of the fuel pump 12 can be detected and the Additional pump 18 can be regulated depending on it.
- the auxiliary pump 18 can be switched to a sufficient To ensure fuel flow to the internal combustion engine. After the start of the Internal combustion engine, for example when a predetermined speed is reached the internal combustion engine, the auxiliary pump 18 can be switched off again. However, it is advantageous to have the auxiliary pump 18 in the acceleration phases of the motor vehicle connect to total the delivery rate of the fuel delivery system 10th to increase and thus allow a small design of the fuel pump 12.
