Description
Technical field
The present invention relates to a kind of sparking plug for internal combustion engine, relate in particular to that a kind of arcing spark is strong, igniting easily, effectively reduces oil consumption, long service life and can self-cleaning spark plug.
Background technology
Along with industrial society is progressive. vehicle growth rate is more and more faster; Spark plug is as the burning things which may cause a fire disaster of car engine ignition, and its function is exactly that the high voltage pulse electric discharge of transmitting by high-voltage conducting wires punctured the air between two electrodes, three electrodes or multi-electrode afterwards, and the burning mixture that the electric arc producing ignites in cylinder is to produce power.And along with industrial technology progress. each depot is when vehicle performance and engine efficiency more and more improve, and spark plug technology but cannot be synchronously and relatively improved, and causes the energy-saving efficiency of automobile to be subject to certain restriction.
Existing spark plug be take L-type as main flow, or polarity, three utmost points and multipole its object of spark plug be all raising ignition success rate, improves fuel efficiency, reaches the object of energy-saving and emission-reduction.Ignition gap is very large on the usefulness impact of spark plug, but will make spark plug performance best efficiency, and in general, this gap is 0.6-1.3mm.Incorrect gap may produce a lot of injurious effects to the performance of the function of spark plug and engine: spark plug gap is larger, the spark of arcing is stronger, and the fuel in the stronger cylinder of spark is not only more easily lighted, and can burn better, so engine starts easily, also can save with oil.But gap more greatly more needs the arcing of high voltage ability, the compression ratio of this outside cylinder is larger, also voltage ability arcing that need be higher, and the voltage that ignition system is supplied with has certain limit, thereby may make spark plug sparking igniting be difficult for and engine is difficult for starting, accelerate unablely, can not run soon, oil consumption is too many.
In addition, no matter existing product single electrode, bipolar electrode or multi-electrode are point-to-point directional discharge igniting, the breakdown point occurring is same fixed point, so will make spark plug life greatly reduce, ignition effectiveness also postpones and reduces because electrode stem loss causes ignition voltage to cross ambassador's ignition effectiveness, causes automobile fuel consumption to increase, exhaust emissions exceeds standard, engine operating temperature improves, and machine oil is aging ahead of time, with car cost, increases.
Summary of the invention
The object of the present invention is to provide the strong and igniting of a kind of arcing spark easily, effectively to reduce oil consumption, long service life and can self-cleaning spark plug.
To achieve these goals, spark plug provided by the invention comprises wiring nut, wiring screw rod, insulating ceramic, metal shell, central electrode, lateral electrode and at least one conduction intermediary, described lateral electrode is annular, described conduction intermediary is fixed between described central electrode and described lateral electrode to insulation, and described conduction intermediary, along the surrounding of described central electrode around forming closing structure, has arcing gap between described conduction intermediary and described central electrode and described lateral electrode.
Compared with prior art, the present invention arranges the conduction intermediary around described central electrode between described central electrode and described lateral electrode, utilize described conduction intermediary not only to make the present invention can increase the ignition gap between described central electrode and described lateral electrode under limited voltage, thereby an arcing spark is strengthened, igniting easily, and make spark plug of the present invention take the mode of annular igniting and produce a plurality of electric arc, thereby further strengthen arcing spark, increase ignition energy, make ignition effectiveness more stable, effectively reduce oil consumption.In addition, during spark plug sparking of the present invention, it in circular gap between described central electrode and conduction intermediary and described conduction intermediary and lateral electrode, is random discharge igniting, therefore, avoid directional discharge igniting to produce loss and reduce useful life same point, greatly extended the useful life of spark plug; And the spark that spark plug of the present invention produces always passes through from the skirt section of insulating ceramic, thereby can burn the carbon distribution in the skirt section that is attached to insulating ceramic, plays automatic cleaning action.
Preferably, described conduction intermediary is annulus.
Particularly, the lateral wall of described annulus has teeth.
Preferably, triangular in shape, the quadrangle of described conduction intermediary or polygonized structure.
Preferably, the quantity of described conduction intermediary is two or more, and is mutually gap and insulation and is socketed.
Preferably, the arcing gap between described conduction intermediary and described central electrode and the width range in the arcing gap between described conduction intermediary and described lateral electrode are 0.6mm-1.2mm.
Preferably, the width in the arcing gap between the arcing gap between described conduction intermediary and described central electrode and described conduction intermediary and described lateral electrode equates.
