Abstract
A multi-electrode multi-direction high-energy spark plug made of noble metal features that the slots are made at the spark end of its iron casing and one or more noble metal electrodes including a central noble metal electrode are welded to make them be uniformly arranged along the circumference. Its advantages are high gas flowability at spark position, high heat dissipating effect and high durability. It is possible to embed said electrodes in an insulating ceramic body and sinter them to become a whole.
Description
Technical field
What the present invention relates to is to be widely used in engine [to comprise all kinds of use gasoline, natural gas, liquefied gas and the diesel oil that may occur etc. needs the engine of all fuel of electronic ignition, (in the present patent application in the literal of back the engine of indication all be meant this type engine)] important electric device in the ignition system, especially to stable, the oil consumption height of engine operating condition, the spark plug that toxic emission has great influence.
Background technology
As everyone knows, present conventional ignition plug structure generally is made up of wiring nut, wiring screw rod, porcelain insulator, sealing material, central electrode, iron-clad, inner washer, outer washer, lateral electrode.Produce ignition energy by arcing gap between high electrical breakdown central electrode and the lateral electrode in use.First spark plug was born over one hundred till now year in the world from 1902, the structure of spark plug ignition end does not still develop into and is producing plural ignition energy together in a flash simultaneously, overcome simultaneously spark plug again and using harmful effect that engine cylinder is produced (have at present get angry the end insulator tip use becket or metal sintered circlewise spark plug, the hidden danger that these spark plugs exist becket or metal powder to come off in use) at spark plug.Present various forms of spark plug all is to form one or more electrode gaps between initial electrode and the one or more grounding electrode, from the nearest principle that punctures of electrode, determined present various spark plug not to be difficult to guarantee dependability produce many igniting energy simultaneously with moment.
Summary of the invention
Existing spark plug only produces single ignition energy when lighting a fire and ignition energy is not a deficiency reliable fully, safety in utilization in order to overcome.The invention provides a kind of spark plug, needed ignition energy when this spark plug can not only produce engine ignition, and producing many igniting energy together in a flash simultaneously, in fact be equivalent to is having many spark plugs to light a fire at the same time in a flash together, and igniting is timely, safe and reliable when having guaranteed use.Thereby impel " detonation " stroke of each engine to produce bigger " detonation " pressure, the fuel mixture burning is more abundant, and engine power increases, and oil consumption reduces, and the toxic emission situation improves significantly.Also improved simultaneously the cold startability of engine greatly.
The present invention solves the technical scheme that its technical problem takes: adopt fluting and chamfering technology at the spark plug iron-clad near getting angry the position of end, while chamfer place end face under iron-clad a plurality of noble metal electrodes that are uniformly distributed along the circumference (also can be that folk prescription is to) of burn-oning.Spark plug porcelain insulator skirt section " buries " near getting angry the position of end that multilayer is arranged (also can be folk prescription to individual layer or folk prescription to multilayer with many noble metals " initial " electrode of circumference, also can be multi-direction individual layer or multi-direction multilayer), every layer of noble metal electrode number of elements is corresponding with noble metal electrode number of elements on the iron-clad, spark plug porcelain insulator skirt section is near the end face fluting of ignition position, end simultaneously, noble metal " initial " electrode that has " is buried " to number identical (noble metal that " burying " has " initial " electrode has several directions just to open several roads groove), direction unanimity near getting angry the position of end in fluting number and porcelain insulator skirt section.The noble metal central electrode make corresponding dendroid embed in the corresponding groove of porcelain insulator skirt section end face and porcelain insulator together sintering (central electrode also can be made the disc shape, porcelain insulator skirt section end face does not need fluting if central electrode is made the disc shape, and the sintering of central electrode then can carry out with the encapsulation of wiring screw rod in the packaging process afterwards together).Form the electrode gap that produces multiple spot fire energy simultaneously together.Equidistant " crest shape " made on top, spark-plug body thermal capacitance chamber, not only can produce the point discharge effect, simultaneously by having improved near the gas flow of spark plug ignition end behind the iron-clad fluting, improved the heat dissipating state of spark plug by cylinder cover, noble metal central electrode afterbody links to each other with high-voltage terminal by noble metal central electrode, conducting medium, wiring screw rod, wiring nut.Using noble metal is the hot adaptability that fully takes into account spark plug as electrode material, with the high-energy ignition effect of giving full play to this neoteric spark plug and the durability of use.Adopt unique technology, multilayer noble metal electrode and dendroid noble metal central electrode did not just combine before insulator also forms porcelain, by high temperature sintering become porcelain fuse into one (sintering of disc shape noble metal central electrode then can packaging process afterwards in and the encapsulation of wiring screw rod carry out together).The fastness and the reliability of noble metal electrode have been guaranteed.The multiple pole and direction arcing gap of the noble metal electrode on after various component-assembled are complete spark plug, just having formed like this on noble metal electrode, the housing with noble metal central electrode, porcelain insulator.
Beneficial effect of the present invention is to form a plurality of ignition energies simultaneously at same ignition point when engine ignition, because ignition energy is big, flame transmission speed is fast, the fuel mixture sufficient combustion, engine power increases, and oil consumption reduces, and the toxic emission situation improves significantly.Also improved simultaneously the cold startability of engine greatly.
