The utility model is characterized in that the side electrode is provided with a golden body structure in the position relative to the center electrode, and the golden body structure is welded or embedded in the side electrode. The utility model has the advantages of 12 percent to 15 percent fuel saving, strong firing force, rapid starting of the vehicle, high durability, no maintenance, air pollution reduction, noise reduction of the vehicle engine, good combustion effect and adaptability in any climate and in any vehicle.
Description
Technical field
The utility model relates to a kind of spark plug, relates in particular to a kind of spark plug that is provided with the gold body in lateral electrode.
Background technique
At present, known spark plug is mainly by contact head, porcelain insulator, and centre electrode, lateral electrode and housing etc. are partly formed.Internal fixation at steel casing has the high alumina ceramic insulator, on the top of insulator center hole metallic rod is arranged, and there is the wiring nut upper end of bar, is used for connecing high-voltage conducting wires, and centre electrode is equipped with in the bottom.Use the conductor glass capsulation between metallic rod and the centre electrode.The shell lower end is fixed with crooked lateral electrode.Centre electrode and lateral electrode all adopt traditional nickel alloy.The gas discharge principle that dissociation becomes electric conductor can take place to spark plug in the influence under certain factor according to gas (air), utilize pulse high-voltage that gasoline engine ignition system produces with formed gap between disruptive spark plug centre electrode and the lateral electrode, when the gap is breakdown, owing to the high-speed motion of ion and electronics forms the red-hot ionization channels of high temperature, and generation spark, thereby light the fuel chambers gas mixed gas in the combustion gas oil unit room, to reach the purpose that makes the engine running acting.Spark plug will bear the impact of high-pressure gas, require spark plug that enough mechanical strengths must be arranged; Spark plug is bearing the high-tension electricity of alternation, requires to have enough insulating strengths; The combustion of mixed gas product is very complicated, contains the various active material, as ozone, carbon monoxide and sulfur oxide etc., easily makes electrode corrosion.Simultaneously, traditional spark clearance mostly is 0.6-0.7mm, and the interelectrode gap of spark plug influences breakdown voltage, so suitable electrode gap will be arranged.Because the ignition voltage of EFI machine is strong especially, candle is fast especially, the life-span is short, igniting is not concentrated so general nickel alloy electrode burns.
Summary of the invention
The purpose of this utility model provides and a kind ofly is provided with the spark plug of gold body in lateral electrode, overcomes the shortcoming of above-mentioned spark plug.
The purpose of this utility model is achieved through the following technical solutions:
A kind of spark plug that is provided with the gold body in lateral electrode, comprise sparking plug body, contact head, centre electrode, lateral electrode, it is characterized in that: be provided with the gold body structure at this lateral electrode position relative with centre electrode, this gold body structure is for welding or being embedded in the lateral electrode, and purpose is to make spark plug can make the contact of gold body structure obtain stable arcing under low voltage, and is more durable, long service life helps motor and keeps good operating mode.Because gold has lower electronics emission potential barrier, promptly under the condition of onesize discharging gap and electrode size, the desired voltage in gap of skipping gold lateral electrode and centre electrode is lower.
This product gold body also has anti-ablation, and is high temperature resistant, the advantage of oxidative stability.
In the utility model, the diameter of this sparking electrode gold body structure is preferably 1.5mm.
Gap between this centre electrode and the lateral electrode is preferably 0.8mm.
Because traditional electrode diameter is 2.5mm, is about 1/3 of traditional sparking electrode area, can keep the higher temperature of electrode like this.The spark clearance size also influences the size of breakdown voltage, because arriving in temperature, the electrode of spark plug just begins more than 580 ℃ to corrode, and along with the corresponding increase of temperature rising corrosion, near 890～1000 ℃, just begin oxidation, if corrode, the corner angle of electrode just become arcuation, and it is big that electrode gap becomes, and will improve the necessary discharge voltage of arcing between electrode like this.Guarantee that suitable breakdown voltage will keep suitable electrode gap, in the utility model, interelectrode gap can be designed to 0.8mm, the anti-ablation of gold simultaneously, and high temperature resistant, the oxidative stability excellent characteristic has guaranteed the long time stability of electrode gap just.
The utlity model has following advantage:
Because lateral electrode has the gold body structure, has definite electrode gap simultaneously, but have fuel saving 1 12 to 1 15, the some firepower is strong, and vehicle launch is rapid, durable in use, need not maintain, reduce atmospheric pollution, reduce the vehicle motor noise, firing effect is good, is fit to the advantage of any weather and vehicle.

Embodiment
Embodiment
A kind of spark plug that is provided with the gold body in lateral electrode as shown in Figure 1 and Figure 2, comprise sparking plug body 1, contact head 2, centre electrode 3, lateral electrode 4, it is characterized in that: be provided with gold body structure 5 at this lateral electrode position relative with centre electrode, this gold body structure is for welding or being embedded in the lateral electrode, and purpose is to make spark plug can make the contact of gold body structure 5 obtain stable arcing under low voltage, and is more durable, long service life helps motor and keeps good operating mode.Because gold has lower electronics emission potential barrier, promptly under the condition of onesize discharging gap and electrode size, the desired voltage in gap of skipping gold lateral electrode and centre electrode is lower.
As shown in Figure 1 and Figure 2 a kind of is provided with the spark plug of gold body in lateral electrode, and with embodiment 1, difference is: the diameter at this sparking electrode gold body structure is 1.5mm, can keep the higher temperature of electrode like this.Gap between this centre electrode and the lateral electrode is 0.8mm, the spark clearance size will guarantee that suitable breakdown voltage will keep suitable electrode gap, interelectrode gap of the present utility model has guaranteed the long time stability of electrode gap just, has guaranteed still can jump out stable spark under lower voltage.Thereby the sparking-plug electrode and the electrode gap index that influence spark plug performance have been improved.
