Abstract
The utility model relates to a spark plug for the ignition of a gasoline engine and a gas engine, more specifically a sparking plug with a lateral electrode in the shape of an annular tooth. The sparking plug with a lateral electrode in the shape of an annular tooth comprises a center electrode and a lateral electrode in the shape of an annular tooth. The utility model is characterized in that lateral electrode in the shape of an annular tooth is provided with a tooth in a ring, and an extension foot at the lower end of the lateral electrode in the shape of an annular tooth is welded with a shell to achieve electric communication. The annular tooth is higher the end face of the center electrode, and does not cover the center electrode, and a certain interstice is formed between the orthogonal projection of the lateral electrode in the shape of an annular tooth along the axial direction of the center electrode and the cylinder face of the center electrode. The lateral electrode in the shape of an annular tooth is provided with a single foot or a plurality of feet which are welded on the shell. Closed angle correspondence is formed between the lateral electrode in the shape of an annular tooth and the external circle of the end of the center electrode. The utility model promotes the sufficient burning of mix gas and diminishes the pollution; the utility model achieves the effect of reliable ignition, rapid start-up, fuel oil saving and enhancement for dynamic power, and has an obvious effect on the gas engine.
Description
Technical field:
The utility model relates to gasoline and spark plug is used in the gas engine igniting, is specifically related to a kind of circular tooth shape multi-gap spark plug.
Background technology:
The spark plug of tradition use at present is the one-sided utmost point, this spark-plug side electrode front end centering electrode top, covered electric spark, limited contacting of electric spark and combustion mixture, improved requirement ignition voltage, the electrode structure of this protected type, to spark plug fire nuclear expansion formation flame arrest effect, reduce spark energy, thereby can cause mixture combustion insufficient, reduce engine power, increase oil consumption and waste gas.
The technical scheme of the utility model circular tooth shape multi-gap spark plug is: a kind of circular tooth shape multi-gap spark plug, comprise central electrode 1 and circular tooth shape lateral electrode 2, it is characterized in that: circular tooth shape lateral electrode 2 is band dentation in the ring, circular tooth shape lateral electrode 2 lower ends are extended pin and housing and are welded together and reach electric connection, the ring tooth depth goes out and does not cover central electrode 1 end face, and the ring internal tooth of circular tooth shape lateral electrode 2 has certain interval along between the axial orthographic projection of central electrode 1 and central electrode 1 face of cylinder.
Above-mentioned circular tooth shape lateral electrode has single or multiple pin to be welded on the housing.Optimal technical solution is that the extension pin of circular tooth shape lateral electrode 2 is made up of double joint, and distributes in central electrode 1 bilateral symmetry.
The interior ring of above-mentioned circular tooth shape lateral electrode has a plurality of crowns.
Principle is in the essential structure that does not change conventional ignition plug, and lateral electrode is improved.Make the lateral electrode front end for band dentation and central electrode end cylindrical in the ring form the wedge angle correspondence, constitute the circular tooth shape multi-gap spark plug with this.
Compared with prior art, the utility model advantage is as follows: the utility model has adopted multipole most advanced and sophisticated Open architecture, makes ignition gap form the wedge angle correspondence.The wedge angle correspondence makes spark plug sparking have point discharge, spark to expand characteristic rapidly forward, promoted the abundant burning of gaseous mixture, reduces and pollutes, and it is reliable to make it reach igniting, starts rapidly, saves fuel oil, increases the effect of power.Make the manufacturing that applies to spark plug of the science of ionisation effect.Owing to adopted multipole most advanced and sophisticated Open architecture, the igniting path is decontroled comprehensively, fire nuclear is grown up rapidly, and it is more abundant to burn, and reduces carbon deposit, increases explosive force, improves power, saves fuel oil, reduces waste gas, has adopted multi-ignition, has improved the reliability of igniting.And the circular tooth shape lateral electrode forms short heterogeneous pathway than traditional lateral electrode, and its conduction heat transfer property is more improved, and has overcome the electric conductivity instability.Avoided because of the too high phenomenon that causes incandescent ignition of lateral electrode surface temperature.Make spark plug work more stable, prolonged useful life.
Description of drawings:
Fig. 1 is the conventional ignition plug structural representation;
Fig. 2 is the structural representation of the utility model circular tooth shape multi-gap spark plug;
Fig. 3 is the axial view of Fig. 2;
Description of reference numerals:
1-central electrode, 2-circular tooth shape lateral electrode.
Embodiment:
Referring to Fig. 1, lateral electrode centering electrode 1 top has covered central electrode 1, forms panelized construction;
Referring to Fig. 2, Fig. 3, circular tooth shape lateral electrode 2 is positioned at central electrode 1 top, and crown leaves the gap, the formation unenclosed construction in its ring between the face of cylinder of the axial orthographic projection of central electrode 1 and central electrode 1.
