Description

Fuel injector
The present invention relates to the especially fuel injector of large two-stroke diesel engine of a kind of internal-combustion engine, it has the shower nozzle of arranging with respect to the firing chamber eccentric axis in the firing chamber that an insertion attaches troops to a unit, shower nozzle has a blind hole that can add fuel, a plurality of spray orifices are from blind hole, they can be contained in the mobile vertically guiding valve of effect that preferably can overcome resetting means in the blind hole under the fuel pressure effect by means of one and control up and down, and in order to produce a common injection a fluid stream, they are arranged in the form that an axis with respect to blind hole in the circumference range relevant with injection direction that is located at blind hole is in the hole row of equal height substantially, wherein the hole axis that comes outside spray orifice slopes inwardly with respect to a radially line stretcher from the blind hole axis at least, makes to spray a fluid stream and obtain a less angle of flare.
Fuel injector by the known a kind of this type of EP 0606371 B1.In the large two-stroke diesel engine with an outlet valve that is located at cylinder head central authorities, fuel injector must be contained in the zone of firing chamber periphery usually.The spray orifice of shower nozzle is arranged as and forms one from the main injection direction of shower nozzle to a side in this case.For avoiding spraying the big transverse scattering of a fluid stream, spray orifice is not disposed radially with respect to the blind hole axis, but a kind of trend towards the deflection of main injection direction is arranged.This causes spray orifice to have different length to have different holes long with circumference along each hole each other.Meanwhile the interior petiolarea at spray orifice forms the very big edge angle of difference.Therefore fuel is entered each spray orifice the diverse condition and thereby produce different speed and flow of becoming a mandarin is provided.Especially among the spray orifice row who forms by a plurality of spray orifices arranged side by side at, exist disadvantageous especially condition in the outside spray orifice district, here because cause the very big wall of difference long along the circumference in each hole.Because especially king-sized wall friction in exterior lateral area so cause a kind of unsettled flowing here, consequently causes spraying a fluid stream and has only carried a spot of air secretly.Worsened thus mixed gas preparation and thereby worsened burning, thereby cause improving fuel consumption and increase emissions figure.
Therefore, setting out thus the objective of the invention is, and takes simple and economical measure to improve the device of the described type of preface, so that can reach burning well and thereby reduction fuel consumption and minimizing emissions figure.
By the present invention is to reach the measure that this purpose takes to be, at least a portion spray orifice sets snout cavity from blind hole, their inside clear width is greater than the diameter of spray orifice, and is designed to make all spray orifices of hole row that similarly length situation is arranged at least each other.
These measures guarantee, unhinderedly enter for fuel at all spray orifices to have essentially identical condition.Therefore can be by means of snout cavity by the constant girth of circumference acquisition of favourable mode along each spray orifice.In like manner can accomplish to make whole spray orifices to have identical substantially hole long.Therefore, cause balanced wall friction and flowing velocity in an advantageous manner by measure of the present invention, thereby obtain a kind of stable injection a fluid stream generally.Especially because this stabilization that in hole row's outside spray orifice district, obtains, guaranteed to go into many air by the jet flow band, this must optimize mixed gas preparation and thereby optimized combustion, consequently reduce fuel consumption, reduce hazardous emission and motor and pollute.Therefore adopt and avoided the described shortcoming of preface fully by measure of the present invention.
The design that above-mentioned measure is favourable has been described in the dependent claims and has conformed with further developing of purpose.For example, appropriate way is that the outside spray orifice that can be at least hole row respectively sets a snout cavity.In hole row's outside spray orifice district by means of can obtain maximum effect by snout cavity of the present invention, because in hole row's outside spray orifice district, there be alarming least stable flowing so far exactly.
By first kind of favourable form of implementation, snout cavity is designed to the hemispheric groove of cross section in the shower nozzle.This hemispheric groove allows to form the edge angle that accurately equates by favourable mode along the whole circumference of spray orifice.What conform with purpose in this case is that hemispheric groove is arranged as on the axis that is centered close to each relevant spray orifice that makes them, so this spray orifice is concentric with respect to the center of relevant snout cavity.
In addition, the semi-spherical grooves that snout cavity is designed in the shower nozzle guarantees that also available simple mode sets a corresponding inlet chamber for each spray orifice, can therefore excessively not weaken shower nozzle.
Another advantage is that semi-spherical grooves undoubtedly can be arranged as, and respectively forms a fixing dividing plate in the zone between two grooves adjacent one another are, and it can play the guiding valve guide plate, prevents worn spool valve thus.
The another kind of favourable design of above-mentioned measure is snout cavity to be designed to the ring section shape groove in the shower nozzle.Therefore can make especially economically.In addition, this design can be in the transition zone between the spray orifice snout cavity relevant with each obtains the edge angle with 90 ° value unanimity with comparalive ease.
Another advantage can think, can be of spray orifice and set a public snout cavity by other spray orifices from the center stack that flanks, and do not weaken shower nozzle egregiously.
Further develop by another of above-mentioned measure, respectively establish in the outer end of spray orifice one preferably the step-like cross section by step-like export mixes enlarge the district.This just formed in an advantageous manner one round the spray orifice outer end and with the interface of orthogonal axe.Guarantee thus to avoid interference the injection a fluid stream, make the jet flow beam stabilization, consequently help entrapped air.Therefore adopt above-mentioned measure further to strengthen the principal advantages that preface of the present invention has been mentioned.
Other favourable designs of above-mentioned measure have been described in remaining dependent claims and have conformed with further developing of purpose, and can be by following by means of further finding out in the explanation of accompanying drawing to embodiment.
Accompanying drawing is represented:
Fig. 1 is by the section by large two-stroke diesel engine nozzle of the present invention;
Fig. 2 by means of one in the spray orifice district, extend pass through the large two-stroke diesel engine nozzle
The horizontal section of shower nozzle represents to have a kind of embodiment of hemisphere snout cavity;
Fig. 3 has the embodiment and the corresponding section of Fig. 2 of ring section shape snout cavity; And
Fig. 4 is along the section of Fig. 3 center line IV/IV.
The basic structure of large two-stroke diesel engine and working method are well-known, therefore can not remake detailed elaboration here.
The nozzle 1 that Fig. 1 represents comprises the shell 2 that a sleeve shape is shunk forward, and it is equipped with a shower nozzle 4 that is shaped on blind hole 3.Shower nozzle 4 passes through a rear portion flange supports on the anterior lip of shell 2.The rear end of shower nozzle 4 is connected with guide pin bushing 5 in being contained in shell 2, and guide pin bushing 5 is shaped on a through hole 6 coaxial with the blind hole 3 of shower nozzle 4.Through hole 6 has a step-like contraction that is designed to valve seat 7, valve body 8 and its mating reaction, and valve body stretches out from the bars 9 that are contained in the guide pin bushing 5.The diameter of valve body 8 is less than the diameter of bar 9, so formed a ring cavity 10 that belongs to hole 6 round valve body 8.
Bar 9 is shaped on being connected with fuel pipe of central authorities and can infeeds the hole 11 of fuel, and it is communicated with ring cavity 10 by inclined hole 12.Be pressed against on the valve seat 7 under the effect of valve body 8 further expression and Returnning springs bar 9 cooperatings in a figure.When the fuel pressure in being in ring cavity 10 correspondingly increased, valve body 8 lifted from the valve seat 7 of attaching troops to a unit, and therefore the zone that is added with fuel was communicated with the blind hole 3 of shower nozzle 4.
Shower nozzle 4 is shaped on the spray orifice 13 that a plurality of cardinal principles are arranged in juxtaposition and extend transverse to the axis of blind hole 3 at equal height in its underpart district, fuel can spray in the relevant firing chamber by them.For not having again fuel to flow out behind the pathway closure that guarantees controlled by valve body 8 from spray orifice 13, be provided with an annular guiding valve 15 that is connected with valve body 8 by bar 14 in the blind hole 3, its lower limb constitutes the control limit of a movement spray orifice 13, this control limit is designed to, when valve body 8 is opened spray orifice 13 when the valve seat 7 of attaching troops to a unit lifts, and when abutting on the valve seat 7, valve body 8 closes spray orifice 13.Fig. 1 has represented this position.
In order to spray into necessary fuel quantity, always be provided with a plurality of along blind hole 3 axially be arranged in the spray orifice 13 that sustained height laterally staggers each other substantially, shown in Fig. 2 and 3.Spray orifice 13 can be arranged as and orthogonal axe, or slightly outward-dipping as shown in Figure 4.Because should too not disperse by the injection a fluid streams that spray orifice 13 forms jointly, so spray orifice 13 is not radially to arrange with respect to the axis of blind hole 3, but with respect to radius towards the deflection of main injection direction, thereby form a less divergence angle or angle of flare.
If spray orifice 13 does not have the variation of cross section continuously until blind hole 3, then each spray orifice 13 forms the widely different each other condition that becomes a mandarin and at the flow condition of each spray orifice 13 inside.Especially here the spray orifice 13 that comprises two outsides among the hole row of four set spray orifices 13 arranged side by side, their length can be more much longer than the spray orifice 13 of inside, and meanwhile the circumference along them can form different length equally in the zone of these outside spray orifices 13.These situations will cause worsening burning and thereby cause high fuel consumption and high emissions figure etc.For fear of this point, for spray orifice 13 sets snout cavity 16 from the blind hole 3s, its inside clear width is greater than the diameter of spray orifice 13.
In pressing the form of implementation of Fig. 2, establish the semi-spherical grooves in shower nozzle 4 17 from the blind hole 3s in order to constitute above-mentioned snout cavity.These semi-spherical grooves 17 can be removed material by electrolysis by means of a kind of equipment by EDM (electrical discharge machining) method work and make easily.Spray orifice 13 itself is simply by means of laser drilling.
Here the semi-spherical grooves 17 of each formation snout cavity is arranged as, and their center is always on the axis of relevant spray orifice 13.Make spray orifice 13 concentric in this way with respect to relevant snout cavity.This centering guarantees that the transition zone between snout cavity and spray orifice 13 forms the edge angle that cardinal principle is constant along whole hole circle week, as among Fig. 2 with label 18 represented.
Attach troops to a unit and determine in such a way in semi-spherical grooves 17 its sizes of spray orifice adjacent one another are 13, promptly, between two semi-spherical grooves adjacent one another are 17, leave a dividing plate 19, it can play the guide plate of annular guiding valve 15, even, do like this and play a part favourable for reaching long working life so guiding valve also can support in the zone of snout cavity reliably.
Just to set snout cavity 16 also just enough for externally spray orifice 13 under special circumstances.In the represented most preferred embodiment of Fig. 2, for all spray orifices 13 set the snout cavity that is made of semi-spherical grooves 17, doing like this must have good combustion position and thereby low especially fuel consumption be arranged.
In the represented embodiment of Fig. 3, set the snout cavity of the ring section shape groove 20 that is designed in shower nozzle 4 for spray orifice 13.Here, the radius of ring section shape groove 20 matches with relevant one or more spray orifices 13, makes the transition zone between snout cavity and the spray orifice 13 form an edge angle that is similar to 90 ° as far as possible, shown in label among Fig. 3 21.
It is contemplated that for each spray orifice 13 set one oneself by ring section 20 snout cavities that constitute.In represented embodiment, be the spray orifice 13 of two central authorities set one public by ring section 20 snout cavities that constitute.This ring section 20 is equivalent to the part with the circular groove of the axis coaxle of shower nozzle 4 blind holes 3, and thinks that the less adjacent ring section 20 of radius that two outside spray orifices 13 set is the boundary.
These outside ring sections 20 are arranged as the center that makes them and are on each relevant axis of spray orifice 13, so spray orifice is concentric with respect to the snout cavity that sets, this has uniformly for the whole circumference along the hole that the condition of becoming a mandarin is favourable.Be that the center of the ring section 20 that sets of two central spray orifices 13 is in the zone between two axis of two relevant spray orifices 13.
In Fig. 3 and 4 illustrated embodiments, be provided with the outlet 22 bigger of a diameter in spray orifice 13 outer ends than spray orifice 13.It causes one to have and the orthogonal axe in the relevant hole step-like cross section expansion regions round the anchor ring 23 of nose end.This outlet 22 guarantees to make the injection a fluid stream of discharging from spray orifice 13 not to be subjected to any interference.
Obviously, it is contemplated that in by the form of implementation of Fig. 2, also establish above the outlet of described form.
Though describe some embodiments of the present invention in detail, should not think to only limit to this.For example can expect immediately, for a part of spray orifice 13 sets the snout cavity that is made of semi-spherical grooves 17 and sets snout cavities that are made of one or more ring section shape grooves 20 for another part, and for example in such a way, promptly, for the spray orifice 13 of outside sets the snout cavity that is made of semi-spherical grooves 17, and be that inner spray orifice 13 sets a public snout cavity that is made of ring section shape groove 20.
