Striking portion is provided with electrode, striking portion draws and bent to direction where main grounding electrode upwards, and striking portion end is positioned at master
Above grounding electrode.When producing electric spark, because central electrode striking portion is arranged on above main grounding electrode, central electrode is eliminated
The shortcomings that electrode stops is grounded, is fully discharged easy to electric spark, improves ignition effectiveness, while main grounding electrode can stop electrical fire
Colored partial heat, reduces heating of the electric spark to insulator, is not likely to produce carbon distribution.
Further, multiple secondary grounding electrodes are additionally provided with the metal shell, multiple pair grounding electrodes are looped around institute
Central electrode surrounding is stated, and between secondary grounding electrode independently of each other.There is no connection relation, pair ground connection between multiple pair grounding electrodes
Electrode will not be covered at the top of the central electrode, during centrally disposed electrode surrounding so that central electrode is set in a manner of opening wide
Put, can more be contacted with gas mixture in combustion chamber, make spark plug fire core more abundant.
Further, the secondary grounding electrode is bent to central electrode, and secondary grounding electrode terminal position is higher than the center
Electrode arc striking portion terminal position.Striking portion to central electrode shields, and avoids striking portion from being produced fracture because of collision.
Further, striking portion end is arranged to aciculiform.According to the principle of point discharge, the striking portion of central electrode
Tip is arranged to, easily carries out arc discharge with the striking portion of another polarity, and then produce electric spark.
Further, the striking portion is iraurite.Using resistance to high temperature oxidation, temperature, which becomes, influences small iraurite, and increase uses the longevity
Life.
Further, boss is provided with the main grounding electrode, lug boss position is corresponding with striking portion end.Set convex
Platform can increase the ignition area between central electrode and main grounding electrode, make the fiery core of generation more abundant, further improve a little
Fiery efficiency.
The beneficial effects of the utility model are：
The efficient sparking plug of the utility model, simple in structure, striking portion is drawn upwards, to main grounding electrode bending and end
Above main grounding electrode, eliminate central electrode and be grounded the shortcomings that electrode stops, electric spark fully discharges, and improves igniting
Efficiency, main grounding electrode can stop the partial heat of electric spark, reduce heating of the electric spark to insulator, are not likely to produce carbon distribution.
