And, at least at least partially coating formed through the following steps to set on the head region (8) : - the header area (8) at least part of the roughness, and the slurry coating to the roughness of the head region (8), - dry coating slurry, heat - coated to the roughness of the head region (8) the slurry to form a porcelain glaze layer (10). The invention also relates to especially flux produced by the method of the internal combustion engine spark plug (1).
Description
The present invention relates to the method for the spark plug according to claim 1 preamble of the explosive motor producing especially motor vehicles.The invention still further relates to the spark plug for explosive motor according to claim 7 preamble.
Application ignited internal combustion engine needs pilot spark, and object is the fuel-air mixture of the compression of lighting in its combustion chamber.For this purpose, the automatically controlled spark plug of the pilot spark being used as controllably to provide respective is used.In their running, pilot spark forms open arc between the central electrode and at least one grounding electrode of spark plug.Spark plug has the main body with connecting portion usually, and connecting portion such as can have external screw thread.Such spark plug can be screwed into the corresponding opening of the cylinder cover of explosive motor.
Connected by the conduction to connecting portion, when spark plug is placed in cylinder cover, grounding electrode is in ground connection by vehicle ground portion.By contrast, central electrode can be connected with ignition coil by such as firing cable.Central electrode can stand by ignition coil the ignition voltage that is applicable to.For this purpose, central electrode and grounding electrode are electrically insulated from each other, because the electric arc of ignition voltage should only produce between two electrodes by the insulator be applicable to.Electrode spacing represents the standard of the burning for obtaining required fuel-air mixture that can pre-set in this.
In the layout of spark plug, it has the combustion chamber of end face to corresponding explosive motor of electrode spacing.For the purposes of the present invention, described end is considered to the head zone of spark plug.
In the process running spark plug, known possible deposit can be formed in its head zone.Deposit is oil carbon normally.These oil carbon deposits are owing to the combustion process of respective fuel.In this case, such deposit mainly concentrates on and is positioned on the SI semi-insulation body of head zone.Depend on running time, these deposits can realize the loose structure with thickness of several millimetres.
The problem produced is owing to the conductivity of the latter.Especially rely on the deposit that formed between the metallic region of the head zone of spark plug, occur the most at last misfiring and the example of uncontrollable pilot spark.And deposit shows at the end of burn cycle with the trend that uncontrollable mode burns away; This and glow plug are similar.Weakening or even imperfect combustion then due to fuel-air mixture, this finally causes the volatile organic matter (discharge of hydrocarbon) in waste gas with undesirable high level.
The spark plug of the known various configuration of prior art.Except they are only used as except igniter, prior art have also been disclosed avoids above-mentioned sedimental technical scheme.
Therefore, EP1557918A1 discloses the spark plug of explosive motor, allegedly because conductive deposit permanently can avoid the generation of shunting.For this reason, suggestion is the layer of precious metal of the catalysis formed on the point foot of the insulator of the head zone being positioned at spark plug.Layer of precious metal can be platinum (Pt), palladium (Pd) or rhodium (Rh).
The noble coatings of suggestion is intended to reduce the temperature needed for combustion deposit.Especially the cold-start phase of explosive motor is interesting, does not wherein also reach optimum operation temperature.Therefore, the reduction of attainable ignition temperature should the sedimental oxidation of final corresponding acceleration.About the position of noble coatings, this is confined to the inner surface of the insulated hole at the central electrode towards spark plug.Conventional insulated hole exposes the insulator inner opening of central electrode to the open air, and central electrode surrounds, so that described central electrode can interact with grounding electrode at other position insulated bodys.
DE4222137B4 discloses the fuel injection nozzle for diesel internal combustion engine.This comprises the nozzle body with spray-hole, and spray-hole penetrates described nozzle body, and until the wall of the nozzle body of applying coating.Coating is thickening towards the opening of spray-hole, so that nozzle bore is tapered towards their opening.Coating itself is by hard material such as chromium, nickel, nickel-phosphorus, nickel-boron, nickel-cobalt-boron, Al

DE19951014A1 discloses the Fuelinjection nozzle of the coating equally with the region at least broadened around floss hole opening.This coating be the oxide of Co or Ni or cobalt oxide or nickel oxide or cobalt alloy or nickel alloy or Ru or Rh or Pd or Os or Ir or Pt or these metals each other or the catalytic active layer of alloy with other metal.
JP2007-309167A discloses the combustion chamber purging system of explosive motor.For this reason, by the surface of titanium dioxide-coated to the injection opening of injector.
JP2005-155618A discloses the technique forming the coating be made up of titanium oxide on the nozzle of injection valve.
Although the layout that result is noble coatings can accelerate the sedimental burning existed, such as its performance and local are arranged result also in and are uncontrollablely lighted and glow.Generally speaking, the technique of therefore following the trail of physics or chemical vapour deposition (CVD) (PVD/CVD) up to now and the technique relating to plating measure generation all can not be made to be applicable to for reliably stoping the coating of sedimental formation and relevant inferior position to become possibility.
Observe according to this, therefore the spark plug of the explosive motor especially explosive motor of motor vehicles certainly still has the space of improvement.
For background technology, the present invention is based on the technique and a kind of spark plug for explosive motor developed further for the production of spark plug, so that the target of the method for the coating providing possible cost-efficient formation to be applicable to, this coating to can be incorporated in existing production sequence and guarantees to improve the reliable effect of the waste gas value formed in running.
The solution of the part that the technique of described target is correlated with is the content of the method for the feature with claim 1.The part that the product of described target is correlated with realizes according to the spark plug of the feature with claim 7.The particularly advantageous improvement of the present invention is open by respective dependent claims further.
It should be noted that and can be combined with each other the method and feature that describe in detail separately in following specification in the technical significant mode of any needs, because further disclosed herein improvement of the present invention.
Accordingly, technique according to the present invention comprises the spark plug producing explosive motor.Particularly preferably, explosive motor is the engine of motor vehicles.
The spark plug that will produce has the main body comprising head zone.Coating is at least partially disposed on head zone.Head zone is designed at least one combustion chamber when spark plug is arranged in explosive motor towards explosive motor.This respect, head zone is placed in relevant combustion chamber at least in part.This respect, head zone is intended to the combustion chamber being assigned to explosive motor.
Preferably spark plug itself has standard design.It comprises central electrode and at least one grounding electrode, grounding electrode and central electrode separate and by least part of combination of insulator relative to central electrode electric insulation.
According to the present invention, by following steps, coating is arranged on the head zone of spark plug:
-make at least part of roughening of head zone,
-will the head zone being coated to roughening be starched,
The slurry of-dry coating,
-heating is coated to the slurry of the head zone of roughening to form enamel layer.
In this regard, be form enamel layer in the head zone of the main body of spark plug according to the essence of technique of the present invention.Compared to providing layer of precious metal, this advantage produced is the deposition having stoped oil carbon according to enamel layer of the present invention to a great extent.At this on the one hand, enamel layer does not play the effect reducing the such temperature needed for deposit of burn off, but stops or at least reduce and formed from the beginning.
---being such as drops---deposits and dries up on enamel layer to cause this knowledge to be in fact do not have the fluid composition of fuel.This has been considered to be in main cause spark plug being formed the lamella as coal tar.So prevent or reduce such deposit to mean that possible its glows be no longer possible at least in a large number.
In addition, enamel layer according to the present invention plays the effect of extra insulator, thus reliably prevents the interruption of possible pilot spark.Deposit is if possible in fact along with the time is formed in head zone, and this is especially correlated with.Because deposit is conductivity, from prior art, if provide the layer of precious metal equally with conductivity that pilot spark that is uncontrollable and that damage so may occur, the present invention can avoid this.
Due to enamel layer according to the present invention, will there is duplicate protection effectively in the operation thus for reliable spark plug, and the result as this correspondingly improves the waste gas value formed in explosive motor running.This reason is caused to be anti-adhesive according to the enamel layer at least in the head zone of relevant spark plug of the present invention and electrical insulation capability.
