Description
Technical field
The present invention relates to field of spark plugs, more particularly to a kind of high stability spark plug.
Background technology
The effect of spark plug is in internal combustion engine, and the high-tension electricity of volts up to ten thousand is introduced into combustion chamber, put by pulsed high-voltage
Electricity, electric current are skipped between electrode, two interelectrode air of disruptive spark plug, are produced heat-flash electric spark, are lighted the oil gas in cylinder
Mixture, produce kinetic energy drive engine.Sparking-plug electrode voltage required when puncturing and producing spark is referred to as breakdown voltage, point
Secondary voltage caused by fire system necessarily be greater than breakdown voltage, can just make spark plug sparking, it is therefore desirable to provide high pressure to spark plug
Electricity.
It can be seen from point discharge principle, conductor tip is sharper, easier generation discharge effect, and spark plug on the market is big
More to be arranged to tip using central electrode, grounding electrode is arranged to the form of transverse slat, during automobile use, if running into voltage
Unstable situation, the power of the discharge spark of spark plug can be made to be affected, and directly result in ignition results decline.Especially exist
Under low voltage condition, because of the energy deficiency of offer, spark plug is unable to normal ignition sometimes, and ignition performance is unstable, lights a fire successfully
Rate is relatively low, causes automobile smoothly to start, or even easily stops working after starting.
The content of the invention
To overcome above mentioned problem, the invention provides a kind of ignition performance it is superior, also can normally start under low voltage situations
High stability spark plug.
The technical solution adopted by the present invention is：
High stability spark plug, including central electrode, central electrode are arranged with insulator, metal are arranged with outside insulator outside
Shell, central electrode and metal shell connect the both positive and negative polarity of power supply respectively, and grounding electrode, the center are provided with metal shell
Electrode includes positive discharge tip, and the grounding electrode includes negative discharge tip, positive discharge tip and negative discharge
Tip bending is relative, forms discharging gap.According to the principle of point discharge, the more sharp easier electric discharge of conductor ends, central electrode
Include discharge tip with grounding electrode and be oppositely arranged, it is easier to arc discharge is carried out, forms heat-flash electric spark, even in
Under low-voltage, plug ignition stability is also can guarantee that, improves ignition success rate, improves ignition results.
Further, the positive discharge tip and negative discharge tip are iraurite.Iraurite price is higher, has anti-height
Temperature oxidation, temperature, which becomes, influences small performance, increases service life.
Further, the grounding electrode lower end is provided with boss-shaped connecting portion, the connecting portion connection negative discharge point
End and metal shell.Iraurite usage amount is reduced, saves material cost.
Further, the positive discharge tip is disposed as strip metal excrescence with negative discharge tip.In order to put
More in place, while heat-flash electric spark makes insulator be not likely to produce carbon distribution to electricity away from insulator.And positive discharge tip and negative pole
Discharge tip surrounding is unobstructed, is easy to electric spark fully to discharge so that gas mixture fully burns, further improve igniting into
Power.
The beneficial effects of the invention are as follows：
The high stability spark plug of the present invention, discharge tip is disposed as by positive pole and negative pole, and two discharge tips are curved
Folding is relative so that discharge effect is more prone between electrode, forms heat-flash spark ignition gas mixture, raising is lighted a fire successfully
Rate, especially under low voltage condition, the Ignition Stability of spark plug is also can guarantee that, improves ignition results.

Embodiment
As shown in Figure 1 to Figure 3, one of embodiment provided by the invention, a kind of high stability spark plug, including central electrode
1, central electrode 1 is arranged with insulator 6 outside, is arranged with metal shell 5 outside insulator 6, central electrode 1 and metal shell 5 are distinguished
The both positive and negative polarity of power supply is connected, grounding electrode 4 is provided with metal shell 5, the central electrode 1 includes positive discharge tip 2,
The grounding electrode 4 includes negative discharge tip 3, and positive discharge tip 2 is relative with the bending of negative discharge tip 3, and formation is put
Electric gap, according to the principle of point discharge, the more sharp easier electric discharge of conductor ends, central electrode 1 includes with grounding electrode 4
Discharge tip and it is oppositely arranged, it is easier to produce discharge effect, heat-flash electric spark is formed, even if at lower voltages, also can guarantee that
Plug ignition stability, ignition success rate is improved, improve ignition results.
The positive discharge tip 2 is disposed as strip metal excrescence with negative discharge tip 3, electric discharge is more arrived
Position, while heat-flash electric spark makes insulator be not likely to produce carbon distribution, and positive discharge tip 2 and negative discharge point away from insulator
Hold 3 surroundings unobstructed, be easy to electric spark fully to discharge so that gas mixture fully burns, and further improves ignition success rate.
Positive discharge tip 2 uses resistance to high temperature oxidation with negative discharge tip 3, and temperature, which becomes, influences small iraurite, and increase makes
With the life-span, the arc stiffness height of formation, temperature are high, and igniting faster, is more concentrated.
The lower end of grounding electrode 4 is provided with boss-shaped connecting portion, the connecting portion connection negative discharge tip 3 and metal
Shell 5, it can effectively strengthen the intensity at negative discharge tip 3 and the junction of metal shell 5, avoid negative discharge tip 3 from connecting
Place is easily broken off, and because negative discharge tip 3 is higher using iraurite material price, sets connecting portion to save negative discharge tip 3
The dosage of middle iraurite material, save material cost.
It is described above, simply presently preferred embodiments of the present invention, the invention is not limited in above-mentioned embodiment, as long as
It reaches the technique effect of the present invention with identical means, should all belong to protection scope of the present invention.
