Abstract
The utility model relates to a four-pole four-way series noble metal high energy sparking plug which can simultaneously generate more than three kinds of ignition energy in the same moment, can improve the burning property of mixed gas of an engine, and can have great advantageous functions for operating conditions, oil consumption, exhaust emission, etc. of the engine. The part of an iron casing of the sparking plug approaching to the ignition end adopts the grooving technology and is provided with a large oblique angle, and the part of the iron casing of the sparking plug approaching to the ignition end is welded with four noble metal electrodes which are uniformly arranged along the circumference, which can realize the pointed end electric discharge property. The flowability of gas near the ignition end of the sparking plug and the heat radiating property of the sparking plug are improved. The durability is enhanced. Eight noble metal electrodes (which are arranged on two layers which are respectively provided with four noble metal electrodes) are uniformly inlaid in the skirt part of a ceramic insulator and are formed into a whole body in a sintering mode. The firmness and the reliability can be ensured. A central electrode adopts noble metal. When the sparking plug is used, a four-pole four-way sparking gap is formed among the noble metal central electrode, the noble metal electrode and the noble metal electrode of the casing. More than three kinds of ignition energy can be simultaneously generated, and a prospective using effect can be obtained.
Description
Technical field
The utility model relates to the important electric device that is widely used in engine [comprise all kinds of use gasoline, natural gas, liquefied gas and the diesel oil that may occur etc. needs the engine (in the present patent application in the literal of back the engine of indication all be meant this type of engine) of all fuel of the electronic ignition] ignition system, especially to stable, the oil consumption height of engine operating condition, the spark plug that toxic emission has great influence.
Background technology
At present, well-known, the spark 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 the 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, from the various forms of till now multi-gap spark plugs of traditional one pole all is to form one or more electrode gaps between central electrode and the one or more grounding electrode, from the principle that electrode punctures recently, determined present various spark plug not producing multiple spot fire 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 enough fully reliably in order to overcome.The utility model provides a kind of spark plug, needed ignition energy when this spark plug can not only produce engine ignition, and producing three igniting energy together in a flash simultaneously, in fact be equivalent to is having three spark plugs to light a fire at the same time in a flash together, this just strengthens the ignition energy with moment greatly, thereby impels in-engine fuel mixture burning more abundant, and engine power increases, oil consumption reduces, and the toxic emission situation improves significantly.
The technical scheme in the invention for solving the technical problem is: take fluting and chamfering at the spark plug iron-clad near the position of ignition end, form four and protrude pointed parts.At four end faces that protrude pointed parts, 4 noble metal electrodes that are uniformly distributed along the circumference of burn-oning.Embed two-layer 8 noble metal electrodes (every layer of each 4 electrode are corresponding) in the aperture that the position that hold near ignition in spark plug porcelain insulator skirt section makes in advance and form the electrode gap that produces ignition energy simultaneously together with the central electrode that noble metal is made with circumference.The noble metals that protrude pointed part end faces welding with close four of getting angry the position, end of spark plug iron-clad form equidistant " crest shape ".Not only can produce the point discharge effect, improve near the gas flow of spark plug ignition end simultaneously, improve the heat dissipating state of spark plug by cylinder cover.Afterbody links to each other with high-voltage terminal by noble metal central electrode, conducting medium, wiring screw rod, wiring nut.Adopt unique technology, two-layer noble metal electrode did not just combine before insulator also forms porcelain, by high temperature sintering become porcelain fuse into one (the noble metal central electrode can with insulator sintering together, also can be in the packaging process of back and sealing material, wiring screw rod sintering together), guarantee the fastness of noble metal electrode.After various component-assembled are complete product, just formed with four four utmost point four-way series noble-metal spark plugs that protrude the noble metal electrode of pointed part end face welding on noble metal central electrode, two-layer noble metal electrode, the housing.
The beneficial effects of the utility model are to form three 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.
