Abstract
The spark plug is composed of central ring electrode, ring lateral electrode. The outer diameter of the central ring electrode is smaller than the inner diameter of the ring lateral electrode, the two electrodes are in different plane, at the ignite moment, the discharge curtain or multiple spark are engendered. Thus the effect on ignition and power of the motor are improved, the oil consumption is reduced.
Description
Double ceramic ring polar inverted arc spark plug relates to the gasoline engine ignition system field.It is made up of central rings (sheet) shape ceramic electrode, ring-shaped pottery lateral electrode etc.Because the special construction of two ring electrodes and position relation make ignition point can produce 360 ° of electric arc heavy curtains of the platform of falling garden lateral area sample.Thereby it is effective to light a fire, and has significantly increased engine power, has saved fuel oil.Be widely used in automobile, motorcycle and the engineering machinery of dress with petrol engine.
Existing spark plug generally is divided into two kinds of one pole and multi-pole types: the lateral electrode of single pole type spark plug is longer than centre electrode, and its region of discharge is blocked (looking from the sparking-plug electrode end) just by lateral electrode, because the diameter of the width dimensions of lateral electrode and centre electrode is suitable substantially, particularly the spark plug pit in after the entrucking because the firing chamber is darker, has formed the situation that is unfavorable for flame propagation again.Therefore, the fire loss ratio height, effectively ignition energy is little, causes engine power to descend, and oil consumption increases.
Its structure characteristic of existing multi-gap spark plug is: a plurality of (being generally three) lateral electrode end bends towards centre electrode simultaneously, and for obtaining discharging gap uniformly, make with the centre electrode axis generouser lateral electrode end is the arc at center.Though solved the front occlusion issue of discharging gap like this, block the side that has produced discharge spark, and the real contact area of discharge spark and mixed gas is little.The igniting effect is still undesirable.In addition, no matter which kind of spark plug center and lateral electrode are Structural Hardware, and it has very strong igniting arc extinguishing effect (being commonly referred to " anti-inflammatory " effect, hereinafter herewith); And centre electrode mostly is the single-column shape, can only produce a flame kernel during discharge, can't make the mixed gas of homogeneity equivalent give play to best work done usefulness.
By above-mentioned analysis, the present invention is proposed, purpose is: overcome the block effect of general spark plug discharge moment lateral electrode to discharge spark, and reduced igniting usefulness; Overcome that conventional ignition plug can only produce discharge spark near the column centre electrode and the defective that forms a less flame kernel; Overcome conventional ignition plug and had to reduce the defective of discharging gap because of " anti-inflammatory " effect of metal film, and propose a kind of, ignition energy is utilized effectively, can produce the discharge condition of 360 ° of scopes and big spacing again, light more a kind of brand-new long lifetime environmental protection and energy saving spark plug--the double ceramic ring polar inverted arc spark plug of weak mixture.
Technical characteristics of the present invention is: pyrolytic coating one deck conductivity ceramics on the insulating ceramic end face of traditional spark plug porcelain body discharge end, form central rings (sheet) electrode, the bigger conduction porcelain ring of certain geometrical shape is embedded on the metal shell of conventional ignition plug discharge end; The relative position relation of two annular electrodes is: plane, central rings (sheet) the stupefied place of electrode discharge ring is lower than ring-type lateral electrode discharge ring plane, stupefied place, and (spark plug is vertically placed, porcelain body is in last position, hereinafter herewith) two planes are same perpendicular to the spark plug axis, and the annular rotational axis of two annular electrodes and spark plug dead in line.The external diameter of ring (sheet) electrode forms certain uniform annular space along the spark plug cross-sectional direction less than the internal diameter of ring-type lateral electrode between two rings; Along spark plug certain clearance also is set axially.Like this, the moment of discharging will form the spark heavy curtain of 360 ° of scopes of the platform of falling garden shape or the multi beam discharge spark of 360 ° of scopes between two annular electrodes, improved ignition performance greatly.On the other hand, be conducting ceramic material because of encircling (sheet) electrode and ring-type lateral electrode, be characterized in corrosion-resistant, anti-galvanic corrosion, so the long service life of spark plug; Because of its heat-insulating property is good, so a little less than " anti-inflammatory " of electrode effect, igniting is reliable; The electrode temperature height, self purification is good, and resistance tocrocking is strong; Therefore pottery is a polycrystalline ceramics, and its material surface forms many microcosmic " peak awns " (crystalline particles forms many cusps), so be easy to electronics emission (point discharge), has realized big gap discharge structure.The ring-type lateral electrode can be formed or directly be made with conductivity ceramics by insulation porcelain ring surface spraying conductivity ceramics.Because central rings (sheet) electrode is lower than the ring-type lateral electrode, thus the electronics emission direction during the igniting discharge just with the electronic current of conventional ignition plug to opposite, so be called inverted arc.
Working procedure of the present invention is: during engine operation, igniting is the moment that primary circuit disconnects, spark coil has just produced high voltage, be added between two annular electrodes of spark plug, when voltage rises to the spark plug gap breakdown voltage, gas in the spark plug gap is ionized generation electric arc (electrical spark) and lights mixed gas, makes the motor work done.Owing to there is a uniform discharging gap between central rings (sheet) electrode and the ring-type lateral electrode, promptly under high voltage, form the region of discharge of an equifield intensity between central rings (sheet) electrode and the ring-type lateral electrode, under the effect of discharge powerful electric current of moment (tens amperes), in case generation electric arc, just form an annular heavy curtain shape 360 ° of discharges table top or a bigger arc region, increased ignition area, shortened the time that flame kernel forms, and can light rarer mixed gas, engine power is increased, and oil consumption reduces.
Therefore, the present invention has following characteristics:＜1 〉, because the maximization as far as possible that central rings (sheet) electrode and ring-type lateral electrode design on diametric(al), make ignition point form big as far as possible seed region, particularly the microcosmic of conducting ceramic material " peak awns " (crystalline particles taper off to a point discharge) be easy to discharge and the heat-conducting property of stupalith poor--high temperature is easy to electronics emission and very weak " anti-inflammatory " of ceramic electrode and acts on two annular electrode discharging gaps are further increased, and can discharge 360 ° of scopes, and discharge is reliable.＜2 〉, because the particular design of central rings (sheet) electrode and ring-type lateral electrode has guaranteed that the waste gas between the sparking electrode can reliably clean out, reduced fire loss ratio.＜3 〉, because central rings (sheet) electrode and ring-type lateral electrode obviously increase with the interior high-temperature gas area of contact of cylinder, and the adiabaticity of stupalith is good in addition, so the temperature height of electrode, self purification is good; The resistance tocrocking of spark plug is strong.＜4 〉, the corrosion resistance of ceramic electrode is strong, galvanic action is little, so be doubled and redoubled the working life of this spark plug.
The present invention has following accompanying drawing
