Definitions
- the invention is based on an injection arrangement for Fuel storage injection system of an internal combustion engine according to the detail defined in claim 1 Sort of out.
- An inward-opening valve will open the valve opens the drainage path, taking fuel flows out of the valve control chamber.
- the associated Pressure drop in the valve control chamber leads to Lift off the nozzle needle from the injector, and it Fuel exits the injector. Will the Drainage again blocked, increases through the over the inflow channel fuel flowing in the pressure in the valve control chamber again. Due to this pressure increase the nozzle needle is again against the injection nozzle pressed and closed it.
- the drainage path and the Inlet channel are usually designed so that with the drainage path open, the flow rate of the over Outflow of effluent fuel greater than the Flow rate of nachf jobden through the inlet channel Fuel is, so that effectively the fuel volume becomes smaller in the valve control chamber.
- the injection arrangement according to the invention for a fuel storage injection system an internal combustion engine with the features of claim 1 has the Advantage that by quickly closing the nozzle needle a high-precision metering of the fuel injection quantity with low leakage and easy to manufacture feasible valve is possible.
- the Injection arrangement a in a combustion chamber of the internal combustion engine protruding, from a high pressure fuel rail of the storage injection system over a high-pressure fuel supply path with fuel supplyable injector and one injector depending on the pressure in a valve control chamber opening and closing nozzle needle.
- For fuel introduction in the valve control chamber opens one of the Fuel supply way branching inlet channel in the valve control chamber, and one of the valve control chamber outgoing expiration path allows the expiration of the Fuel from the valve control chamber.
- shut-off device provided by means of which the drainage - related in a fuel drain direction - downstream the junction of the auxiliary channel in the drainage path can be blocked against fuel drainage.
- the shut-off also for Blocking of the auxiliary channel formed against fuel flow is, in such a way that when the drain path is blocked the auxiliary channel is unlocked and vice versa.
- the auxiliary channel be locked. If the drainage path during an injection process opened so can be prevented that fuel from the fuel supply via the auxiliary duct runs off unused.
- the auxiliary channel in essentially exclusively with regard to optimized be that the valve control chamber after blocking the drainage path is refilled as quickly as possible and so the nozzle needle as soon as possible back into their Closed position is moved.
- shut-off device two separately actuated shut-off for the auxiliary channel and the drainage path. This can be, for example be useful if the auxiliary channel and the drainage path not time-synchronized, but time-delayed opened or should be blocked. With less effort, a solution can be realized in which the Shut-off device for blocking the drainage path and the Lock the auxiliary channel to a common shut-off having trained shut-off surfaces.
- shut-off body as between two opposite valve seats is formed reciprocable seat element, wherein one of the valve seats a shut-off for the desertweg forms and the other valve seat a shut-off forms for the auxiliary channel. It is conceivable but also that the shut-off as a slide element a slide valve is formed.
- shut-off device For actuating the shut-off device may preferably serve a piezoelectric actuator assembly, alternatively but can also be an electromagnetic actuator assembly be provided.
- the storage injection system shown in Figure 1, which a so-called common rail injection system represents, has a symbolically indicated pressure source 10 on, preferably diesel fuel under one high pressure of, for example, more than 1500 bar in a distributor pipe or rail 12 feeds. From the manifold 12 go several fuel supply lines 14 off, the fuel for each one in a Combustion chamber 16 of a multicylinder not shown Combustion engine, for example one Motor vehicle internal combustion engine, projecting injection nozzle 18 serve.
- the injection nozzle 18 is part of a general 20 designated injector, which as a preassembled unit in a cylinder block the internal combustion engine can be used.
- the injector assembly 20 has a housing assembly 22 with a nozzle housing 24 and a valve housing 26th on.
- nozzle housing 24 In the nozzle housing 24 is one along a housing axis 28 extending guide bore 30 is formed, in which an elongated nozzle needle 32 is guided axially movable is.
- the nozzle needle 32 At a needle point 34, the nozzle needle 32 a closing surface 36, with which they in dense Attachment to a needle housing formed on the nozzle housing 24 38 is brought.
- the nozzle needle 32 is biased by a biasing spring 44 in FIG Direction biased to its closed position.
- the biasing spring 44 is formed in a nozzle housing 24 in the Spring chamber 46 housed. She supports herself on the one hand via the combustion chamber remote end of the nozzle needle 32 sealing, but axially movable receiving, biting into the valve housing 26 with a biting edge Sleeve 48 on the housing assembly 22 from. on the other hand it relies on a plugged onto the nozzle needle 32 Spring plate 50 on the nozzle needle 32 from.
- a valve control chamber 58 limited, in the one as Throttle formed inlet channel 60 opens.
- Fuel from the spring chamber 46th flow into the valve control chamber 58.
- About one Outflow throttle 62 containing flow channel 64 can Fuel from the valve control chamber 58 to a not drain discharge space shown in detail.
- the flow areas of the always open inlet throttle 60 and the outlet throttle 62 are so one another tuned that the inflow through the inlet throttle 60 is less than the drain through the drainage channel 64 and thus a net outflow of fuel results.
- the following pressure drop in the valve control chamber 58 causes the closing force below the opening force drops and the nozzle needle 32 from the needle seat 38 to the inside takes off.
- shut-off valve 68 returned to its locked position. This Locks the fuel drain through the drainage channel 64th Through the inlet throttle 60 continues to flow fuel from the spring chamber 46 into the valve control chamber 58, and the pressure in the valve control chamber 58 rises again at. As soon as the pressure in the valve control chamber 58 a Level reached at which the closing force greater than the opening force is, the nozzle needle 32 goes into their Closed position, which is the fuel outlet from the nozzle hole arrangement 40 stops.
- auxiliary channel 72 is provided by means of whose closed shut-off valve 68 an additional Fuel flow into the valve control chamber 58 achieved becomes.
- the auxiliary channel 72 branches off from the bore 52 and becomes just like the inlet throttle 60 with fuel fed, which is substantially below the rail pressure stands.
- the additional fuel flow through the Auxiliary channel 72 leaves after blocking the shut-off valve 68th the pressure in the valve control chamber 58 faster than with sole filling by the inlet throttle 60th rise again to the level necessary for the Nozzle needle 32 from its opening into its closed position to convict. Ultimately, so can the in the combustion chamber 16 injected fuel quantity finely dosed become.
- the shut-off valve 68 does not control only the fuel drain through the drainage channel 64, but also the fuel flow through the auxiliary channel 72. It is designed as a 3/2-way valve, the three Connections of one - related to the flow direction of the fuel flow upstream portion 64 'of the drain passage 64, a downstream portion 64 '' of the drainage channel 64 and the auxiliary channel 72 are occupied.
- the shut-off valve 68 locks the downstream Part 64 "of the drain channel 64, but there is one Flow connection between the auxiliary channel 72 and the upstream part 64 'of the drainage channel 64 free. In this first switching position is thus a fuel drain from the valve control chamber 58 to the relief space impossible, a fuel flow over the Auxiliary channel 72 and the upstream portion 64 'of the drain channel 64 in the valve control chamber 58, however, possible.
- an opening position performing Switching position allows the shut-off valve 68 the Fuel drain from the valve control chamber 58 through the upstream part 64 'of the drainage channel 64 in however, its downstream portion 64 "locks it Auxiliary channel 72.
- a fuel flow through the auxiliary channel 72 thus occurs in the second switching position not on, so in this second switch position via the effluent from the valve control chamber 58 Fuel quantity no leakage accepted must become.
- the shut-off valve 68 is in the embodiment shown here as a seat valve with one in a valve chamber 74 arranged seating element 76, in this case one spherical valve closure member formed.
- the seat element 76 is by means of the actuator 66 between two in Adjustment of the actuator 66 opposite seats 78, 80 adjustable, one seat 78 of the first Switching position corresponds and whose other seat 80 the second switching position corresponds.
- the downstream portion 64 "of the drainage channel opens 64 in the valve chamber 74, the seat 80 of the Auxiliary channel 72.
- the upstream portion 64 'of the drainage channel 64 opens laterally between the two seats 78, 80 in the valve chamber 74. In this way, the Requirement to be met that the shut-off for the Drain channel 64, which is formed here by the seat 78, downstream of the point at which the auxiliary channel 72 in an imaginary, along the two parts 64 ', 64 "of the drainage channel 64 via the valve chamber 74 running expiration path opens.
- the seat element is shown by a solid line or valve closure member 76 shown in contact with the seat 78. Dashed the second switching position is indicated, in which the seat member 76 rests against the seat 80. It is understood that the proportions in Figure 2 is not are true to reality.
- the adjustment of the seat element 76 between the two seats 78, 80 can easily in the range of only a few tens or hundreds of microns lie.
- the seat member 76th by means of a recognizable in Figure 1, in the valve chamber 74 accommodated valve spring 82 against the seat 78th be biased.
- the auxiliary channel 72 is over its entire length without essential throttle point executed. Because he is downstream the outlet throttle 62 in the mentioned imaginary Drains anyway, there is anyway a throttle point, namely the outlet throttle 62, in the flow path, the locked shut-off valve 68 via the auxiliary channel 72 in the valve control chamber 58 going Fuel flow travels.
