Abstract
The utility model relates to a spark plug for the ignition of a gasoline engine and a gas engine, more specifically a spark plug with a toothed side electrode. The spark plug with a toothed side electrode comprises a center electrode and a toothed side electrode. The utility model is characterized in that the upper end of the toothed side electrode is in the shape of a tooth point, and the lower end of the toothed side electrode is welded with a shell to achieve electric communication. The tooth point is higher the end face of the center electrode and does not cover the end face of the center electrode, and a certain interstice is formed between the orthogonal projection of the toothed side electrode along the axial direction of the center electrode and the cylinder face of the center electrode. The toothed side electrode is single, or two toothed side electrode are uniformly distributed, and a corresponding closed angle is formed between the toothed side electrode and the external edge of the end of the center electrode. The utility model promotes the sufficient burning of the mixed gas and diminishes the pollution; the utility model achieves 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 gear-side electrode 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 gear-side electrode is: a kind of gear-side electrode spark plug, comprise central electrode 1 and gear-side electrode 2, it is characterized in that: gear-side electrode 2 upper ends are tooth tip shape, gear-side electrode 2 lower ends and housing weld together and reach electric connection, crown exceeds and does not cover central electrode 1 end face, and gear-side electrode 2 has certain interval along between the axial orthographic projection of central electrode 1 and central electrode 1 face of cylinder.
Above-mentioned gear-side electrode is single or uniform two.Optimal technical solution is that gear-side electrode 2 is made up of double joint, and distributes in central electrode 1 bilateral symmetry.
The end of above-mentioned gear-side electrode is unicuspid tooth, bidentate, multiple tooth and rectangular teeth or circular convex tooth.
Principle is in the essential structure that does not change conventional ignition plug, and gear-side electrode is improved.Making the gear-side electrode front end is tooth tip shape, and its gear-side electrode can constitute and outer, central electrode end forms the wedge angle correspondence with single, double joint, constitutes the gear-side electrode 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 bilateral ultimate ratio tradition lateral electrode forms short heterogeneous pathway, 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 gear-side electrode surface temperature.Make spark plug work more stable, prolonged useful life.
