Definitions

  • the invention relates to a fuel injection device according to the preamble of Patent claim 1.
  • Fuel injection systems of the type mentioned are by the AT 002 961 U2, the WO 99/18349 A1 or US 5,213,084 has become known.
  • the fuel injection device is pressure-controlled.
  • a pressure-controlled fuel injection device is understood to be moved by the pressure prevailing in the nozzle chamber of an injector fuel pressure valve member against the action of a closing force (spring), so that the injection port for injection of the fuel from the nozzle chamber is released into the cylinder ,
  • injection pressure The pressure with which fuel exits the nozzle chamber into a cylinder of an internal combustion engine
  • system pressure is understood to mean the pressure below which fuel is available or stored in the fuel injector.
  • Leakage is understood to mean an amount of fuel that arises during operation of the fuel injection device (eg a pilot leakage ), is not used for injection and is conveyed back to the fuel tank.
  • the pressure level of this leakage may have a steady state pressure, with the fuel subsequently being expanded to the pressure level of the fuel tank.
  • the injection pressure can be adapted to load and speed become.
  • a pilot injection is often carried out here.
  • to Reduction of emissions is known as a pressure controlled injection Cheap.
  • a pressure controlled injection Cheap In the known pressure-controlled common rail systems per injector However, a consuming to be manufactured 3/2-way valve or it will be two 2/2-way valves used.
  • a pressure-controlled fuel injection device 1 promotes a variable-volume fuel pump 2 fuel 3 from a storage tank 4 via a feed line 5 in a central pressure storage chamber 6 (common rail), of which several, the number of individual cylinders corresponding pressure lines. 7 to the individual, in the combustion chamber of the engine to be supplied protruding injectors 8 (injector) dissipate.
  • a system pressure is generated and stored in the pressure storage chamber 6 at a pressure of 300 to about 1800 bar.
  • metering valves 9 which are 2/2-way valves are formed.
  • the metering valve 9 is a directly operated force-balanced Magnetic valve. But it can also be a piezoelectric actuator with a corresponding coupler space. With Help the metering valve 9, the injection pressure-controlled for each cylinder is realized.
  • the pressure line 7 connects the pressure storage chamber 6 with a nozzle chamber 10. Die Injection takes place with the aid of an axially displaceable in a guide bore piston-shaped valve member 11 with a conical valve sealing surface 12 at its one End, with it with a valve seat on the injector housing of the injector. 8 interacts. At the valve seat surface of the injector housing are injection openings intended. Inside the nozzle space 10 is an opening direction of the valve member 11 pointing pressure surface 13 exposed to the pressure prevailing there, which the Nozzle space 10 is supplied via the pressure line 7. All pressure lines 7 are over Check valves 14 to a central, d. H. intended for all pressure lines 7 Pressure relief valve 15 is connected, the pressure relief of a pressure line. 7 after the injection allows. During the injection process is the respective Pressure line 7 separated from the leakage line 16. Prevent the check valves 14 that from the required for injection pressure line 7 fuel in another temporarily Unnecessary pressure line 7 can get.
  • the pilot injection takes place with the pressure relief valve 15 closed and with it open Metering valve 9, which is energized to open.
  • metering valve 9 After opening the metering valve 9 is running a high-pressure fuel shaft in the pressure line 7 to the nozzle chamber 10.
  • the valve member 11th is lifted against a restoring force of the valve seat and the injection process can start.
  • the fuel high pressure shaft also enters a sealed Leakage line 17. This branch reduces the pressure of the in the nozzle chamber 10th inflowing fuel with respect to the pressure in the pressure storage chamber 6. Die Pre-injection therefore takes place at a lower pressure than that in the Accumulator chamber 6 prevails.
  • the leakage lines 17 and the nozzle chamber 10 is the reduced Fuel pressure wave just so big that only the pre-injection takes place and no Can be done after spraying. Reflected fuel pressure waves are caused by the Branching to the leakage line 17 steamed.
  • the pressure lines 7 and leakage lines 17 should be the same in terms of cable length be configured to the same hydraulic conditions for all injectors 8 create.
  • the injector 8 according to FIG. 1 has a seat or blind hole nozzle.
  • Fig. 2 shows instead of this geometry a Vario or a Vario-register nozzle of an injector 18 of a second embodiment.
  • the injection process can be better adapted to the requirements of the engine.
  • the actuation of the valve member 21 or a hydraulic stroke stop of the valve member 21 can take place both locally within the injector and centrally for all injectors simultaneously.
