Definitions
- the invention is based on a fuel injection valve according to the preamble of the main claim.
- Fuel injection valves which a disc for Determining a metered amount as a component possess, are out DE 36 43 523 A1 known. You own a disc, in the fuel channels are introduced. These Fuel channels have a tangential component, the the velocity vector of the flow with a Peripheral component provides. The through the total cross section the fuel channels open flow cross-section acts limited to the flow rate. The throttling of Flow creates a pressure drop across the disc leading to the Training a sealing surface pressure and the Prevention of bypass routes is used. The metering of the fuel and, where appropriate, the training of a Twists take place upstream of the sealing seat.
- Fuel injector has one with a blind hole provided on valve closing body, in the interior of the Fuel reaches above the valve seat surface. at open fuel injector enters the fuel by radially arranged flow channels from the Valve closing body, bounces on the valve seat surface and then exits the fuel injector.
- the fuel injection valve according to the invention with the Characteristic features of claim 1 has the other hand the advantage that the metering of the fuel does not over the cross-sectional area of the swirl channels takes place.
- the metering of the fuel does not over the cross-sectional area of the swirl channels takes place.
- Another advantage is the small change in the Injection image both in terms of the Zumeßmenge and the spray angle over the life of the Fuel injector. Dirt particles in the Fuel can cause a clogging of individual Lead swirl channels. In the embodiment according to the invention this is due to the high number of swirl channels a merely minor change in the Total cross section of the swirl channels, resulting from a Variety of individual swirl channels composed.
- By the Metering of fuel in directly subsequent swirl chamber is doing no Quantity change. Also in the other flow path can do not form deposits. Due to the high Flow rate of the fuel in the Swirl chamber is maintained become deposits prevented.
- the fuel injection valve 1 is in the form of a Fuel injection valve for fuel injection systems of mixture-compacting, externally ignited Internal combustion engine running.
- the Fuel injector 1 is particularly suitable for direct injection of fuel into one illustrated combustion chamber of an internal combustion engine.
- the fuel injection valve 1 consists of a Nozzle body 2, in which a valve needle 3 is arranged.
- the valve needle 3 is in operative connection with a Valve closing body 4, with one on one Valve seat body 5 arranged valve seat surface 6 to a Tight fit together.
- the fuel injection valve 1 is it in the exemplary embodiment to an inward opening electromagnetically actuated Fuel injection valve 1, which via a Spray opening 7 has.
- the nozzle body 2 is through a Seal 8 against the outer pole 9 of a magnetic coil 10th sealed.
- the magnetic coil 10 is in a coil housing 11 encapsulated and wound on a bobbin 12, which rests against an inner pole 13 of the magnetic coil 10. Of the Inner pole 13 and the outer pole 9 are through a gap 26th separated and based on one Connecting component 29 from.
- the magnetic coil 10 is connected via a Line 19 of a via an electrical plug contact 17th energized electric current.
- the plug contact 17 is surrounded by a plastic sheath 18, the Inner pole 13 may be molded.
- the valve needle 3 is in a valve needle guide fourteenth guided, which is designed disk-shaped. to Stroke adjustment is a paired shim 15.
- An the other side of the dial 15 is a Anchor 20. This is about a first flange 21st non-positively connected to the valve needle 3 in conjunction, which by a weld 22 with the first flange 21 connected is.
- On the first flange 21 is supported Return spring 23 from which in the present design of Fuel injection valve 1 by a sleeve 24 Bias is brought.
- the armature 20 and in the Swirl disk 35 extend fuel channels 30a, 30b and Swirl channels 36 which the fuel, which has a supplied central fuel supply 16 and by a Filter element 25 is filtered to the injection opening 7 in lead the valve seat body 5.
- the fuel injector 1 is replaced by a seal 28 against a not shown Distribution pipe sealed.
- the armature 20 drops sufficient reduction of the magnetic field by the pressure of the Return spring 23 on the first flange 21 from the inner pole thirteenth from, causing the valve needle 3 against the stroke direction emotional.
- the valve closing body 4 is placed on the Valve seat surface 6, and the fuel injection valve. 1 will be closed.
- the metering of the fuel takes place in the According to the invention executed fuel injection valve. 1 by limiting the flow through one flowing cylinder jacket surface in the swirl chamber 37, following a swirl disk 35, as in Fig.2 represented is located.
- Fig. 2 shows in an excerpted sectional view first embodiment of the swirl disk 35 with subsequent swirl chamber 37 of an inventive Fuel injection valve 1.
- the swirl disk 35 is disk-shaped and is in one cylindrical recess 40 of the valve seat body fifth fixed. For attachment, the swirl disk 35 be pressed for example in the valve seat body 5. In axial direction remains between valve seat body 5 and Swirl disk 35 a gap of height h.
- the swirl disk 35 has a central bore 38 for guiding the Valve closing body 4. The bore 38 is opposite to the Diameter of the valve closing body 4 tolerated so that a between the valve closing body 4 and swirl disk 35 as Secondary flow path for the fuel-forming gap is prevented.
- the swirl chamber 37 is cylindrical and is in the height h through the valve seat body 5 and the swirl disk 35 limited.
- the relevant for the metering of the fuel Throttle is characterized by a cylindrical surface, the preferably is smaller by at least a factor of 1.5 as the sum of the cross-sectional areas of the swirl channels 36, educated.
- the diameter of the swirl channels 36 is smaller than that Diameter of dirt particles that are in the fuel are located.
- the swirl disk 35 thus complements the function of Filters 25.
- the height h of the swirl chamber 37 is by a stop 39th fixed.
- the swirl disk 35 is so far in the Valve seat body 5 introduced until it on the stop 39th is applied.
- the stopper 39 may take the form of a in the cylindrical recess 40 of the valve seat body fifth be designed protruding annular paragraph.
- a stop 39 is omitted on a stop 39 .
- the swirl disk 35 can in axial direction within the cylindrical recess in Valve seat body 5 arbitrarily positioned and fixed there be, e.g. by a press connection with the Valve seat body 5.
- the setting of the limiting throttle point takes place Positioning the swirl disk 35 in the valve seat body 5.
- Die Swirl disk 35 is up to a predetermined position in introduced the valve seat body.
- the actual flow rate through the swirl chamber 37 is measured.
- the actual flow rate and change the position of the Swirl disk 35 are repeated until the desired flow rate is achieved substantially.
- the measurement of Actual flow rate can be used to avoid residues, e.g. done pneumatically.
- a tolerance range can be specified when it is reached the positioning is ended.
