Abstract
The utility model relates to a circular ring double iridium electrode spark plug which comprises a central electrode, a circular ring side electrode, a sealing washer, an iron casing, conductive glass cement, an insulating porcelain body, a binding screw and a binding nut. An iridium sheet is welded at the sparking end of the central electrode, and an iridium contact is welded inside the circular ring side electrode and a groove is also formed inside the circular ring side electrode. The structure can ensure more mixed gas passing through the electrode, the ionization rate of the mixed gas is increased under the effect of edge effect high electric field, to produce strong electrical breakdown sparks, and as circular ring opened multiple electrodes continuously discharge electricity, the area of the electric spark is large, the flash suppression effect of the electrode is less, and a flame core is rapidly grown up, to ensure that weak mixture and natural gas are sufficiently burnt. Therefore, the purposes of waste gas purification and fuel consumption reduction are achieved. The circular ring double iridium electrode spark plug can perform multiple-electrode flashover, and has the advantages of small electrode dissipation, low required voltage, long ignition duration time, higher power, lower fuel consumption, less pollution, good heat dispersion, simple manufacture process, and durability.

Background technology
The spark plug that uses on most in the prior art gasoline engines is single gap plug, this spark plug fire's point of origin face is little, requirement voltage height, spark energy is low, lateral electrode shielding shape stops flame propagation, influencing gaseous mixture fully burns, power performance is poor, and part is not fired gasoline and become exhaust emissions, has not only wasted energy but also contaminated air, patent 01258571.8 circular arc multi-gap spark plug and the thin electrode spark plug of patent 200620066545.3 annulars have changed traditional single gap plug shape, multiple spot arcing function is arranged, but still come with some shortcomings, for example lateral electrode can strengthen the arcing gap because of edge corner angle loss, make and require voltage to raise the arcing decreased performance.
Summary of the invention
The purpose of this utility model provides the two iridium electrode spark plugs of a kind of annulus, central electrode is got angry at holding and is welded with the iraurite sheet, annulus lateral electrode inboard is welded with iraurite sheet contact, and be provided with groove, this structure can make more gaseous mixture pass through electrode area, under the effect of rim effect highfield, gaseous mixture quickens ionization, produce stronger electrical breakdown spark, owing to be the multipole continuous discharge of annulus open type, the electric spark area is big, the flame arrest effect of electrode is little, flame nuclear shoots up, and lean mixture, natural gas are fully burnt, and reaches the purpose of waste gas purification and reduction oil consumption.
The utility model is by central electrode, the annulus lateral electrode, seal washer, iron-clad, electro-conductive glass glue, insulating ceramic, wiring screw rod, the wiring nut is formed, by screw thread, the face of cylinder, in the iron-clad that six prismatic surfaces surround insulating ceramic is housed, central electrode is housed in the insulating ceramic, diameter is got angry at holding for the 0.4-1.2mm central electrode and is welded with thick 0.4-1.0mm iraurite sheet, the annulus lateral electrode has 1 or 2 pin to be welded on the iron-clad, its inboard is welded with 1-4 thick 0.4-1.0mm iraurite sheet contact, and be provided with wide 0.5mm, dark 0.5mm groove, be hollow-core construction, the unsettled central electrode top that is positioned at, constitute the inclined-plane gap between annulus lateral electrode and the central electrode, the arcing gap of central electrode and annulus lateral electrode is 0.6-1.2mm, seal washer is contained on the iron-clad, and insulating ceramic has screw thread outward, and wiring screw rod is equipped with in the lower end, wiring screw rod one end has screw thread, the conical surface is arranged outward, and wiring screw rod cooperates with the wiring nut, and central electrode and wiring screw rod link by electro-conductive glass glue.
The multipole arcing of the utility model energy, export license is little, requires voltage low, and ignition duration is long, has improved power, has reduced oil consumption, has reduced pollution, and thermal diffusivity is good, and manufacturing process is simple, durable.
