Definitions
- the invention is based on a fuel injection system for an internal combustion engine according to the preamble of the claim 1.
- Such an injection system is for example by the EP 0 711 914 A1 has become known.
- a pressure-controlled fuel injection system is controlled by the pressure prevailing in the nozzle chamber of an injector fuel pressure valve body (eg a nozzle needle) against the action of a closing force and thus released the injection port for injection of the fuel.
- the pressure with which fuel exits the nozzle chamber into the cylinder is referred to as injection pressure.
- a stroke-controlled fuel injection system is understood to mean that the opening and closing of the injection opening of an injector take place by means of a displaceable valve member due to the hydraulic interaction of the fuel pressures in a nozzle space and in a control space.
- an arrangement will be referred to as central if it is common to all cylinders, and local if provided for only a single cylinder.
- JP 06 093936 A and EP 0 740 067 A are Fuel injection systems with a first accumulator for the higher fuel pressure and a second pressure accumulator fed from the first accumulator known.
- the injection system according to the invention has to achieve an improved dosage of the deeper fuel pressure the characterizing features of claim 1 on. Inventive developments are in the dependent claims contain.
- the lower fuel pressure is proposed not central, but for each injector respectively to control locally via a valve unit. by virtue of the short line between local valve unit and nozzle chamber Injector losses are kept to a minimum reduced.
- the pre and post injection with the lower fuel pressure and in a reduced influence of component tolerances on the pre and post injection.
- a pressure-controlled fuel injection system 1 promotes a volume-controlled fuel pump 2 fuel 3 with a pressure of about 300 to 1800 bar from a storage tank 4 via a feed line 5 in a first central pressure accumulator 6 (common rail) and into a second central pressure accumulator 7 (common rail), of which in each case several, the number of individual cylinders corresponding pressure lines 8 and 9 to the individual, projecting into the combustion chamber of the engine to be supplied pressure-controlled injectors 10 (injector) dissipate.
- injector injector
- a first higher fuel pressure of up to 1800 bar is generated, which is stored in the first pressure accumulator 6.
- the fuel under this pressure is also conveyed into the second pressure accumulator 7, in which by regulating its fuel supply by means of a 2/2-way valve 11, a second lower fuel pressure of about 300 bar is maintained.
- a control loop with a pressure sensor is provided in each case.
- the lower pressure level can be used for a pilot injection and, if required, also for a post-injection (HC enrichment for exhaust gas aftertreatment), while a main injection with the higher fuel takes place from the high-pressure accumulator 6.
- the switching between either the lower or the higher fuel pressure takes place separately for each cylinder or injector 10, in each case via a local valve arrangement 12 , which has a 2/2-way valve 13 as the switching element for the higher fuel pressure in the pressure line 8. Its output is decoupled from the pressure line 9 through a check valve 14 . Via a 3/2-way valve 15 , the respective present pressure is then passed via a pressure line 16 into a nozzle chamber 17 of the injector 10.
- the injection is pressure-controlled by means of an axially displaceable in a guide bore piston-shaped valve member 18 (nozzle needle), the conical valve sealing surface 19 cooperates with a valve seat on the injector and thus closes the injection openings 20 provided there.
- a pressure surface of the valve member 18 facing in the opening direction of the valve member 18 is exposed to the pressure prevailing there, wherein the nozzle chamber 17 continues through an annular gap between the valve member 18 and the guide bore to the valve sealing surface 19 of the injector 10.
- the injection openings 20 sealing valve member 18 is controlled against the action of a closing force (closing spring 21 ), wherein the spring chamber 22 by means of a leakage line 23 is depressurized.
- the injection with the lower fuel pressure takes place at no-current 2/2-way valve 13 by energizing the 3/2-way valve 15.
- the injection with the higher Fuel pressure is at energized 3/2-way valve 15th by energizing the 2/2-way valve 13, wherein the check valve 14 an unwanted return to the pressure line 9 prevented.
- the 3/2-way valve 15 on Leakage 23 switched back. This will cause the pressure line 16 and the nozzle chamber 17 depressurized, so that the spring-loaded valve member 18, the injection openings 20th closes again.
- the generally designated in Fig. 1 by 24 array of local valve assembly 12 and 3/2-way valve 15 may be inside the injector (Fig. 1a) or outside the injector (Fig. 1b), for example in the region of the pressure accumulator 6, 11 be arranged.
- a smaller size of the injector and by utilizing wave reflections in the now longer pressure line 16 can achieve an increased injection pressure.
- the higher fuel pressure of the first pressure accumulator 6 is distributed centrally to the individual injectors 10 via a distributor device 31 .
- the metering of the fuel stored in the first pressure accumulator 6 is centrally controlled by a 3/2-way valve 32 in front of the distributor device 31.
- the switching between the two pressure lines 8, 9 takes place for each injector 10 in each case locally via the generally designated 33 valve arrangement, in which a 3/2-way valve 34 is provided as a switching element.
- the injection with the lower fuel pressure takes place with energized 3/2-way valve 32 by energizing the 3/2-way valve 34, while the injection with the higher fuel pressure at energized 3/2-way valve 32 and 3 / unpowered 2-way valve 34 takes place.
- the 3/2-way valve 32 is switched back to leakage 35 in de-energized 3/2-way valve 34, whereby the manifold 31 and the injector 10 are depressurized.
- the local valve unit 33 can be arranged either inside the injector housing ( FIG. 2a ) or outside it ( FIG. 2b ).
- the injection system 40 differs by the use of the local valve assembly 33 and the use of stroke-controlled injectors 41 , of which only one is shown in more detail.
- a stroke-controlled injector 41 on the valve member 18 coaxial with the valve spring 21 to a pressure piece 42 , which limits the valve sealing surface 19 end face 43 a control chamber 44 .
- the control chamber 44 has from the pressure line 16 ago a fuel inlet with a first throttle 45 and a fuel outlet to a pressure relief line 46 with a second throttle 47 which is controllable by a 2/2-way valve 48 to 49 leakage.
- the pressure member 42 is pressurized in the closing direction.
- valve assembly 33 may be located either within the injector housing ( FIG. 3a ) or outboard ( FIG. 3b ).
- Piezo plates enable faster valve switching times and a better dosing option.
- a piezo plate can also be on one or both Chokes in the stroke-controlled injector are dispensed with.
- the injection system 50 ( FIG. 4 ), which otherwise corresponds to FIG. 3b, has modified stroke-controlled injectors 51 , each with a piezo-controlled 3/2-way valve 52 .
- the control chamber 53 of each injector 51 is filled as a volume, which is connected via the 3/2-way valve 52, with only one supply line from the pressure line 16 forth or relieved via the leakage 54 .
- For an injection with the respective in the pressure line 16 pending fuel pressure of the also under this pressure control chamber 53 is relieved by energizing the 3/2-way valve 52, and the injection is stroke-controlled.
- a fuel injection system 1 for an internal combustion engine different with the fuel with at least two high fuel pressures via injectors 10 in the combustion chamber of the internal combustion engine to be injected can, with a central first accumulator 6 for the higher fuel pressure and one from the first accumulator 6 fed central second pressure accumulator 7, in the by regulating its fuel supply the lower fuel pressure is maintained, and with a valve unit to switch between the higher and the lower Fuel is the valve unit 12 for switching between the higher and the lower fuel locally for each injector 10 is provided.
- this injection system is an improved dosage of the lower fuel pressure possible.
