Background technology
The effect of spark plug is a high voltage pulse discharge of electricity of sending high-voltage conducting wires here, and air between disruptive spark plug two electrodes produces electric spark with the mist in this cylinder that ignites; The primary condition of high-performance generator is: the spark that high-energy is stable, the gaseous mixture that mixes, high compression ratio; It is thus clear that the significance level of spark plug.Spark plug is all arranged on the gasoline engine generator, one in a cylinder, the every cylinder of individual other high speed petrol engine also is equipped with two spark plugs.Spark is plugged with insulator and metal shell two big parts: metal shell is threaded, and is used to be screwed into cylinder; Insulator is housed in housing, and its inside is connecting a central electrode, there is the wiring nut central electrode upper end, connects the high-tension bus-bar of coming from distributor cap; Lower surface at housing is welded with grounding electrode, and the gap of 0.8～1.3mm is arranged between central electrode and the grounding electrode, and high-tension electricity through this gap spark ignition gaseous mixture of will setting out out with going into.Existing spark plug configuration generally comprises housing, ceramic insulation, central electrode and a curved lateral electrode, between central electrode and curved lateral electrode, produces electric spark through electrion during igniting, thus the fuel in the ignition combustion chamber; Common spark plug is owing to be non-resistance, and single-point is lighted a fire, and spark is few; Energy is low, is prone to carbon distribution, and Electromagnetic Interference is strong; Low temperature is difficult for shortcomings such as startups, and the use of incompatible present car influences the operate as normal of automobile engine electrical equipment.
Summary of the invention
It is wider that the object of the invention provides a kind of spark, and the spark point of generation is many, igniting more easily, environmental protection and energy saving, the resistance type multi-ignition spark plug more fully of burning.
The present invention adopts following technical scheme for realizing above-mentioned purpose:
A kind of spark plug; Comprise housing, ceramics insulator, be arranged in central electrode, transition electrode, the wiring screw rod that links to each other with central electrode and the wiring nut of ceramics insulator; The configuration resistance is 3～12K Ω glass fiber resistance between said central electrode and the wiring screw rod; The limit of central electrode extends to outside the housing; When the limit end is arranged on electrion can and transition electrode between produce five jiaos of sheet metals of 2～8 electric sparks, ceramics insulator is arranged in the housing, the end near transition electrode on the housing is provided with lateral electrode; It is characterized in that above-mentioned lateral electrode) the end several prodgers are set.
Reasonablely be, the transition electrode of stating of the present invention is " L " shape sheet metal, and several extensions towards five jiaos of sheet metals are set on the transition electrode, and said extension is corresponding each other with prodger.The height of prodger is 2～6mm.
Reasonablely be, transition electrode of the present invention is the metal ring of a kind of material in platinum or chromium gold or nickel chromium triangle gold or the yttrium gold, and the thickness of metal ring is 0.8～2mm.
Reasonable is that each angle of five jiaos of sheet metals of the present invention is protruding laterally.
Reasonablely be that the material of five jiaos of sheet metals of the present invention is a kind of in platinum or chromium gold or nickel chromium triangle gold or the yttrium gold.
Reasonablely be, the thickness of five jiaos of sheet metals of the present invention is 0.8～2mm, and circumscribed circle diameter is 5～8mm.
Reasonable is that the distance between five jiaos of sheet metals of the present invention and the transition electrode is 0.4～1.5mm.
The present invention adopts technique scheme; Compared with prior art have following advantage: the present invention is rational in infrastructure; Use glass fiber to do resistance and played the effect that shielding electromagnetic wave is disturbed, also protect the normal use of electrical equipment in engine control computer and the car, effective Financial cost is low.In addition, between the five jiaos of sheet metals and transition electrode on central electrode top, when high-tension ignition, can produce 2～8 electric sparks; Ignition operation is reliable, and ignition energy is big, and can practice thrift fuel oil; Reduce toxic emission, improved combustion rate temperature and also started easily when extremely low.The present invention adopts dual ignition " V " type layout, can be so that the spark of ignition zone nuclear strengthen one times, and spark is wider, and the spark point of generation is many, thereby realizes igniting more easily, environmental protection and energy saving, the purpose more fully of burning.
