Abstract
The utility model discloses a spark plug comprising an insulating housing and a wiring screw installed in the insulating housing. The end portion of the wiring screw is connected electrically to a central electrode. The spark plug is characterized in that a metal wire A is connected onto the central electrode; a plurality of side electrodes cooperating with the central electrode is disposed on the insulating housing; and the end portions of the side electrodes are connected to a metal wire B. The metal wire A is an iridium platinum wire welded at the end portion of the central electrode and having a diameter of 0.2-1mm. The metal wire B is an iridium platinum wire welded at the end portions of the side electrodes and having a diameter of 0.2-1mm. According to the utility model, iridium platinum is good in high temperature resistance; the service life is longer; the ignition energy is concentrated; more sufficient burning of the engine is ensured with higher service efficiency and larger power improvement space; and a lot of energy is saved and good economical efficiency is obtained.
Description
Technical field
The utility model belongs to the engine fittings field, specifically, relates to a kind of spark plug.
Background technology
Spark plug is an important accessory in engine, its effect is that its effect is the high voltage pulse discharge of electricity that high-voltage conducting wires is sent here, lateral electrode in the disruptive spark plug and the air between central electrode, produce electric spark with the mist in this cylinder that ignites, and produces power.
But existing spark plug, after long-time the use, can cause the damage of material of central electrode and lateral electrode due to a variety of causes, cause igniting to have some setbacks, impact is used, and has also wasted many energy.And, also need often to change spark plug, caused like this rising of use cost.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defect, provides a kind of ignition energy to concentrate, guarantee that engine combustion is more abundant, and service efficiency is high, power-lift, the saving energy, spark plug with good economy.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of spark plug comprises insulation crust and is arranged on the wiring screw rod in insulation crust that the end of wiring screw rod is electrically connected with central electrode, it is characterized in that: be connected with wire A on described central electrode; Be provided with the some lateral electrodes that match with central electrode on described insulation crust, the end of lateral electrode is connected with wire B.
Described wire A is welded on the iridium platinum wire that central electrode end, diameter are 0.2-1mm.
Described wire B is welded on the iridium platinum wire that lateral electrode end, diameter are 0.2-1mm.
The number of described lateral electrode is one, two, three, four or five.
Owing to having adopted technique scheme, compared with prior art, be welded with the iridium platinum wire on lateral electrode of the present utility model, be welded with the iridium platinum wire on central electrode, use a plurality of lateral electrodes and a central electrode to form the most advanced and sophisticated spark plug electric discharge of iridium platinum wire.Iridium platinum resistance to elevated temperatures in the utility model is good, and useful life can be longer, and ignition energy is concentrated, and can guarantee that engine combustion is more abundant, and service efficiency is higher, and the power-lift space is large, and has saved a large amount of energy, has good economy.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
The accompanying drawing explanation
The operation principle schematic diagram that Fig. 1 is a kind of embodiment of the utility model.
In figure: the 1-wiring screw rod; The 2-insulation crust; The 3-central electrode; 4-wire A; 5-wire B; The 6-lateral electrode.
Embodiment
Embodiment:
As shown in Figure 1, a kind of spark plug comprises insulation crust 2 and is arranged on the wiring screw rod 1 in insulation crust 2 that the end of wiring screw rod 1 is electrically connected with central electrode 3.In the utility model, be connected with wire A4 on described central electrode 3, be provided with the some lateral electrodes 6 that match with central electrode 3 on described insulation crust 2, the end of lateral electrode 6 is connected with wire B5.
In the present embodiment, described wire A4 is welded on the iridium platinum wire that central electrode 3 ends, diameter are 0.2-1mm.Described wire B5 is welded on the iridium platinum wire that lateral electrode 6 ends, diameter are 0.2-1mm.In actual use, the diameter of iridium platinum wire is 0.5mm, is a kind of selection of the best, certainly, also can adopt the diameter of other numerical value.
The number of lateral electrode is definite according to actual needs, and generally, the number of described lateral electrode 6 is one, two, three, four or five.
Be welded with the iridium platinum wire on lateral electrode of the present utility model, be welded with the iridium platinum wire on central electrode, use a plurality of lateral electrodes and a central electrode to form the most advanced and sophisticated spark plug electric discharge of iridium platinum wire.Iridium platinum resistance to elevated temperatures in the utility model is good, and useful life can be longer, and ignition energy is concentrated, and can guarantee that engine combustion is more abundant, and service efficiency is higher, and the power-lift space is large, and has saved a large amount of energy, has good economy.
The utility model is not limited to above-mentioned preferred implementation, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or akin technical scheme, all belong to protection range of the present utility model.
