Description
Technical field
The present invention relates to a kind of igniter of petrol engine, especially a kind of spark plug of more ignitors.
Background technology
With the popularization of automobile, the scope that engine uses is more and more wider, therefore crucial portion during for engine start
The requirement more and more higher of part spark plug.It is insufficient such as such as to occur ignition energy in engine cold-start, the flame arrest problem of spark plug,
Engine is set to be not easy to start；It is slower in conventional ignition plug Initial Stage after Ignition flame, reduce the utilization ratio of fuel；Combustion process
In, due to high temperature and the effect of chemical attack, more corrosion occurs in both positive and negative polarity, and electrode resistance increases, and adds igniting
Difficulty；In addition with the continuous improvement of compression ratio, to reduce the generation of pinking, also plug ignition efficiency is proposed higher
It is required that.At present, single gap plug is used still than wide, but in view of the above-mentioned problems, then needs to study multi-gap spark plug.
The content of the invention
Present invention aims at providing, a kind of ignition success rate is high, ignition effectiveness is high, the positive pole ceramics bag of service life length
Wrap up in type multi-gap spark plug.
To achieve the above object, following technical scheme is employed：The invention mainly comprises grounding nut, ceramics insulator,
Wiring screw rod, shell, packing ring, central electrode and lateral electrode, screw thread are processed in wiring screw rod, the central electrode is wrapped in pottery
Inside porcelain insulator, the lateral electrode is round tube shape structure and the coaxial socket of the central electrode with being wrapped in ceramic insulation body is solid
It is fixed；The bottom of central electrode is less than the bottom of lateral electrode, and three L-type ignition powers equidistantly arranged are welded in central electrode bottom
Pole, the front end of L-type ignitor is bent upwards and ensures that the end face of front end is in level, in ignitor in addition to front end surface
Surface spraying ceramic coating；The bottom of lateral electrode is along the circumferential direction equidistantly machined with three downward projection of boss, and three
Corresponding up and down and gap is equal one by one for the end face of boss and three L-type ignitors of central electrode.
In addition, the bottom of central electrode can also be less than the bottom of lateral electrode by the present invention, three are welded in central electrode bottom
The individual Metal Flake ignitor equidistantly arranged, and Metal Flake ignitor and central electrode are in vertical state；Will
Metal Flake ignitor and center cathode one spraying ceramic coat, expose after the front end surface polishing of three ignitors
Metal end face；The bottom of the lateral electrode is along the circumferential direction equidistantly machined with three downward projection of boss, and three boss
Corresponded with the end face of three Metal Flake ignitors of central electrode and gap is equal.
The course of work approximately as：
When engine start is struck sparks, ignition system primary circuit disconnects moment, and secondary ignition coil sensing produces high voltage,
It is loaded between the positive pole of spark plug and negative pole, when voltage, which increases to, is enough to puncture the value of positive and negative clearance between poles, disruptive spark plug
Gas in gap, produces electric arc between both positive and negative polarity, lights mixed gas, makes engine start.When lighting, spark plug bag
Network is inside insulating ceramics and only exposes end face, and spark plug can be incubated, and reduces flame arrest effect, ignition arc direction is along fire
The axially distribution of flower plug, beneficial to the removing of waste gas between both positive and negative polarity, improves the reliability of igniting.
Compared with prior art, the invention has the advantages that：
1st, three ignitors being welded on central electrode are uniformly distributed, and can produce three electrical discharge arcs in igniting,
Multiple flame kernels are formed, ignition success rate can be protected, and can effectively postpone same operating mode down-firing advance angle so that whole combustion
Burning process accelerates burn rate, can effectively lift mean effective pressure in the thermal efficiency and cylinder, improve hair closer to isochoric combustion
The dynamic property of motivation.
2nd, three ignitors are integrally placed in inside ceramics insulator together with spark plug inside center electrode, only three points
The end face of thermoelectricity pole is exposed, and ceramics insulator plays the role of adiabatic heat-insulation, and spark plug electricity can be substantially reduced at the initial stage of igniting
The flame arrest effect of pole, the efficiency of igniting is improved, simultaneously because ceramics insulator effectively prevent spark to the parcel of ignitor
The generation of electrode focus is filled in, reduces the generation of pinking, improves spark plug life.
3rd, due to axial direction of the gap of spark plug positive pole and negative pole along spark plug, therefore the waste gas in discharging gap can be ensured
It can be removed during in-cylinder air motion, ensure that the success rate of igniting, reduce oil consumption.
4th, change the number of poles of electric discharge by adjusting voltage under different operating modes, power consumption during electric discharge can be reduced, save
About electric energy.
