The present invention is characterized in that the side electrode comprises a plurality of metal circular rings which are positioned on the insulator at the lighting end of the spark plug, and a central electrode is connected with a polygonal metal sheet. When the present invention discharges in a high voltage mode, multiple-point electric sparks are generated between the circular rings and the metal sheet and among the circular rings.
Description
The present invention relates to a kind of annular multi-pole energy-saving spark plug, it is used for internal combustion engine, especially for petrolic igniter.
Spark plug is used the ceramics material manufacturing usually, as shown in Figure 1, comprises a housing, a pottery magnetic insulation body, and a central electrode and a lateral electrode during igniting, produce electric spark by electrion between central electrode and lateral electrode, thus the fuel in the ignition combustion chamber.Common spark plug owing to be the single-point igniting, so it is unreliable to work, and usually produces carbon distribution, and lost efficacy plug ignition in use.
The purpose of this invention is to provide a kind of novel annular multi-pole spark plug, it can overcome the shortcoming of existing spark plug, realizes multi-point spark, thereby can improve the reliability and the efficiency of engine of lighting a fire, and can save fuel oil and the minimizing pollution to environment.
The invention provides a kind of novel annular multi-pole spark plug, it comprises a housing, one pottery magnetic insulation body, one is arranged in the central electrode of pottery magnetic insulation body, one lateral electrode, one wiring screw rod that links to each other with central electrode and a wiring nut, described lateral electrode comprises the number of metal annulus, be positioned on the insulator of plug ignition end, connect a polygonal sheet metal on the central electrode, when electrion, between annulus and sheet metal, and produce the multiple spot electric spark between annulus and the annulus, and it is characterized in that: described hexagon sheet thicknesses is 1mm, diagonal-size is 6mm; And, be 3-5mm to the igniting total backlash the housing end face from described hexagon sheet metal.
The present invention also provides a kind of manufacture method of annular multi-pole spark plug, it is characterized in that: central electrode and hexagonal connected mode are to protect with argon gas, tie point is from molten, and the molten certainly time is 2.5 Φ 3.5/2.5 seconds of Φ, makes the hexagonal disks end face and the gap of meeting and discussing between end face is not more than 0.2mm; The connection of lateral electrode annulus notch portion is to protect with argon gas, and tie point is from molten, and the molten certainly time is 1 Φ 1.5-1.8mm/1.5 second of Φ, and internal radius is not more than 0.02mm with the annular groove fit clearance of meeting and discussing.
Adopt annular multi-pole spark plug of the present invention, can form multi spot spark when igniting, so ignition energy is big, ignition operation reliably especially at the Shanxi severe cold season, starts vehicle easily.And fuel can fully be burnt, thus the energy fuel savings, and minimizing is to the pollution of environment.
Present invention is described below by embodiment and with reference to accompanying drawing.
Fig. 1 is the cutaway view of existing spark plug;
Fig. 2 is the cutaway view of annular multi-pole spark plug of the present invention;
Fig. 3 is the end view of annular multi-pole spark plug head among Fig. 2, produces the state of multiple spot electric spark when schematically having shown spark plug work;
Fig. 4 is the top view of annular multi-pole spark plug head of the present invention;
Fig. 5 is the mounting means figure of annular multi-pole spark-plug side electrode of the present invention and central electrode.
As shown in Figure 2, annular multi-pole spark plug of the present invention comprises a housing 1 and a pottery magnetic insulation body 2, at an end of pottery magnetic insulation body 2 wiring nut 3 and wiring screw rod 4 is arranged, with a central electrode 7, its top connects a polygonal sheet metal 10, and in the present embodiment, sheet metal 10 is a hexagon sheet metal, central electrode 7 is contained in pottery magnetic insulation body 2 inner chambers, and fill with glass conducting resinl 5, seal washer 6 is arranged on the jointing end face of housing 1, also comprise an inner washer 9 in the spark plug bottom.Spark plug of the present invention also comprises a lateral electrode 8, and lateral electrode 8 comprises number of metal ring 8a, 8b (being two in the present embodiment), and in other embodiments of the invention, becket can only be one.Becket 8a, 8b are embedded in the groove of pottery magnetic insulation body 2 ends.The direction of six angle becket 8a of the sheet metal 10 of central electrode is extended (as shown in Figure 4), so, at sheet metal 10 and becket 8a, form a plurality of gaps between 8b and the housing end face (negative electrode) 11, the distance from hexagonal sheet metal 10 to housing end face 11 is about 5mm.
When spark plug is worked, owing to, form a plurality of gaps between 8b and the housing end face 11 at hexagonal sheet metal 10 and becket 8a, so, can on a plurality of positions, form a plurality of electric sparks randomly around central electrode, thereby form the relay-type arcing, as shown in Figure 3.So, increased ignition energy, improved the reliability of igniting, particularly under the situation of cold season or fuel gasification condition difference, its effect is more remarkable, makes the startup of vehicle easy, can reduce carbon distribution simultaneously when burning, thereby improved the burning of fuel, reached fuel savings and reduced less environmental contamination.
Total ignition distance of annular multi-pole spark plug of the present invention reaches 3-5mm, and is multi-point spark, compares with the single-point ignition gap of the 0.6-1mm of common spark plug, and its total ignition energy has improved greatly.Show by bench test engine, annular multi-pole spark plug of the present invention can form 10-20 electric spark when work, compare with the engine that uses common spark plug, and hundred kilometers oil consumptions reduce by 5%, the discharging of CO has reduced by 14%, and the HC discharging has reduced by 73.3%.Thereby realized that igniting of the present invention is reliable, the purpose that fuel saving and minimizing are polluted.
The present invention also provides a kind of manufacture method of annular multi-pole spark plug, has shown the mounting means figure of annular multi-pole spark-plug side electrode of the present invention and central electrode among Fig. 5.
Wherein, described central electrode and hexagonal connected mode are to protect with argon gas, and tie point is from molten, and the molten certainly time is 2.5 Φ 3.5/2.5 seconds of Φ, make the hexagonal disks end face and the gap of meeting and discussing between end face is not more than 0.2mm.
The connection of lateral electrode annulus notch portion is to protect with argon gas, and tie point is from molten, and the molten certainly time is Φ 11.5-1.8mm/1.5 second, and internal radius is not more than 0.02mm with the annular groove fit clearance of meeting and discussing.
The present invention can have many modification, all among the present invention's spirit scope.
