Definitions

  • the invention relates to a method for operating a Fuel supply system for an internal combustion engine in particular a motor vehicle in which fuel from pumped into a pressure accumulator and from Injectors directly into the internal combustion engine is injected.
  • the invention further relates to a Fuel supply system for an internal combustion engine in particular a motor vehicle with a pressure accumulator and a pump with which the pressure accumulator fuel is feedable, and with injectors with which Fuel can be injected directly into the internal combustion engine is.
  • the object of the invention is to provide a method for operating of a fuel supply system for one To create an internal combustion engine with which one as possible optimal starting of the engine is feasible.
  • This task is carried out in a procedure or a Fuel supply system of the type mentioned at the beginning solved according to the invention in that an electrical Fuel pump and a downstream electric High pressure pump to pump the fuel into the Pressure accumulators are provided together with the ignition be turned on to one for injection to generate sufficient pressure in the pressure accumulator.
  • an electric pump for generation of pressure used.
  • This electric pump is put together with the ignition and therefore preferably before the starter switched on. So that the electric pump pressure required for normal operation in the Pressure accumulator built up to the actual starting process become.
  • the method according to the invention can also be in the form of a Control can be realized for a control unit an internal combustion engine, in particular one Motor vehicle is provided. It is on the Control stored a program on a Computing device, in particular on a microprocessor, executable and for executing the invention Process is suitable. Can be used as a control in particular an electrical storage medium for use come, for example a read-only memory.
  • Fuel supply system 1 shows a fuel supply system 1 shown for use in an internal combustion engine a motor vehicle is provided.
  • Fuel supply system 1 is a so-called common rail system, which is particularly in one Internal combustion engine with gasoline direct injection Application comes.
  • the fuel supply system 1 has a pressure accumulator 2 on, with a pressure sensor 3 and a Pressure control valve (DSV) 4 is provided.
  • the accumulator 2 is via a pressure line 5 with a mechanical High pressure pump 6 connected.
  • the high pressure pump 6 is with coupled to the internal combustion engine and generates one High pressure with the internal combustion engine rotating.
  • the High pressure pump 6 is connected via a pressure line 8 to the Pressure control valve 4 is connected.
  • Over a Pressure line 9 and a filter is the pressure control valve 4 and thus also the high pressure pump 6 with an electric one
  • Fuel pump 10 connected, which is suitable Suck fuel from a fuel tank 11.
  • the electric fuel pump 10 generates pressure as soon as there is a tension on it. This is at least briefly the case when the ignition of the motor vehicle is turned on is.
  • the fuel supply system 1 has four Injectors 13 on the pressure lines 14 with the Pressure accumulator 2 are connected.
  • the injectors 13 are suitable for fuel in appropriate combustion chambers to inject the internal combustion engine.
  • the pressure sensor 3 is connected by means of a signal line 15 connected to a control unit 16 to which a further A plurality of signal lines other than input lines are connected.
  • a signal line 17 Fuel pump 10 and via a signal line 18 is that Pressure control valve 4 connected to the control unit 16.
  • Pressure control valve 4 connected to the control unit 16.
  • Of the injection valves 13 are also means Signal lines 19 connected to the control unit 16.
  • the fuel from the fuel pump 10 to the fuel tank 11 the high pressure pump 6 is pumped.
  • a pressure is generated in the pressure accumulator 2 the pressure sensor 3 is measured and by a corresponding actuation of the pressure control valve 4 and / or Control of the fuel pump 10 to a desired value can be controlled and / or regulated.
  • About the Injector 13 is then the fuel in the Combustion chambers of the internal combustion engine injected.
  • the quantity of fuel to be injected is, among others Pressure in the pressure accumulator 2 is essential.
  • This pressure in the pressure accumulator 2 can be from can be controlled and / or regulated by the control unit 16.
  • control unit 16 controls, for example Pressure control valve 4 in its closed state, so that the high pressure pump 6 and fuel pump 10 always one Generate further increasing pressure in the pressure accumulator 2. This increasing pressure can be from the pressure sensor 3 be measured.
  • control device 16 Speed of the fuel pump 10 increases, resulting in a increased delivery capacity of the fuel pump 10 leads and has an increased pressure in the pressure accumulator 2.
  • the increase in this pressure and thus the increase in Speed or the delivery rate of the fuel pump 10 can also be determined via the pressure sensor 3.
  • the ignition is the Internal combustion engine not yet switched on and the Starter of the internal combustion engine has not yet been actuated.
  • the starter moves Internal combustion engine in a rotary motion.
  • the starter it is preferably a so-called starter generator or similar.
  • the speed N of the Internal combustion engine becomes non-zero and rises quickly on.
  • the starter reaches within a low Duration, preferably within a few revolutions of the Internal combustion engine about the idle speed NL the Internal combustion engine.
  • Pressure control valve 4 Before time t1, i.e. before switching on the ignition and before starting the starter, it can Pressure control valve 4 opened in any state or be closed.
  • Pressure accumulator 2 is the one required for normal operation There is pressure.
  • the pressure control valve 4 is thus with the Cycle ratio N controlled according to normal operation and / or regulated.
