Abstract
The utility model relates to a self-contained type spark plug, comprising a conducting screw (1), a central electrode (7), conducting glue (6), an insulating ceramic body (2), a metal shell (4) and a small sealing ring (8), wherein the skirt part and the wall of a central hole of the insulating ceramic body are respectively plated with a metal film; a metal film surface (9) of the skirt part of the insulating ceramic body is connected with the metal shell by the small sealing ring; and a metal film surface (3) of the ceramic hole wall of the insulating body is connected with the conducting screw by the conducting glue. Therefore, due to the adoption of the self-contained type spark plug, parts of the spark plug are reduced, the processing technique is simple, the yield is high, the cost is low, and the installation is convenient.
Description
Technical field
The utility model relates to a kind of self-tolerant spark plug, belongs to gasoline engine spark plug parts (H01T13/02).
Background technology
The spark plug of Shi Yonging is made up of metal shell, lateral electrode, conductive lever, nut, central electrode, electro-conductive glass glue, insulating ceramic and big or small seal washer in the market.This spark plug weak point is that the electrical breakdown spark energy is not strong, and the gasoline atomizing gas firing gets insufficient, wastes gasoline and makes motor vehicle exhaust emission bad, contaminated environment, cold start is poor, and engine chamber and spark plug easily produce carbon deposit, cause engine overheat.External like product adopts the circumscribed capacitor, is installed on the top wiring conductive lever of spark plug, and purpose is to improve spark plug electrical breakdown energy.The capacitor of producing as the smart steel of Japanese woods Co., Ltd. that constitutes by insulator and inside and outside metal sleeve and big or small jump ring, its big or small jump ring is connected respectively with housing, the wiring conductive lever of spark plug, thereby increased spark plug electrical breakdown energy, make the gasoline atomizing gas firing abundant, reach the clean purpose of motor vehicle exhaust emission.But its weak point is complex structure, and the installation formality is loaded down with trivial details, has increased driver and maintenance personal's work difficulty and labour intensity.
The interior condenser type spark plug of prior art China's utility model patent 89218426.4 (notification number CN2060018U), its formation is the capacitor that increases a metal film on market in the existing spark plug insulator, one utmost point of capacitor is capacitor to be linked to each other with housing by the hole on porcelain tube with power spring, and a utmost point is that the inwall metal face of capacitor links to each other with electro-conductive glass glue conductive lever.Purpose also is to improve spark plug electrical breakdown energy.But its undesirable place still is the processing technology complexity, the percent defective height.
The utility model content
The utility model is the improvement to above-mentioned prior art, and purpose provides that a kind of assurance technical indicator is functional, and quality is really up to the mark, and processing technology is simple, and part reduces, and cost is low, and the self-tolerant spark plug of qualification rate 100% is easy for installation.
The design that achieves the above object is as follows:
The self-tolerant spark plug comprises conductive lever 1 and central electrode 7, conducting resinl 6, and insulating ceramic 2, the metal shell 4 of band lateral electrode 5, small sealing ring 8 is characterized in that, the skirt section of insulating ceramic 2 and its center hole wall be metal-coated membrane respectively, forms capacitive element; The skirt section metal face 9 of insulating ceramic 2 is connected with metal shell 4 through small sealing ring 8, and the center hole wall metal film face 3 of insulating ceramic 2 is connected with conductive lever 1 through conducting resinl 6.
The utility model is to utilize capacitor energy store electrical energy and moment to emit the characteristics of electric energy, the self-tolerant spark plug makes capacitor moment also emit the electric energy of storage in discharge, thereby increases the energy of spark plug electrical breakdown, 1.5-2 doubly, the indoor combustible gas of engine combustion is fully burnt.Reduced the part of spark plug, processing technology is simple, and product percent of pass can bring up to 100%, has reduced cost.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the profile of self-tolerant spark plug.(metal shell 4 ends 11 are the riveted state not)
Embodiment
The self-tolerant spark plug comprises conductive lever 1 and central electrode 7, conducting resinl 6, insulating ceramic 2, the metal shell 4 of band lateral electrode 5, small sealing ring 8 is metalworks, the skirt section of insulating ceramic 2, promptly insulating ceramic 2 is put into part and its center hole wall difference metal-coated membrane of metal shell 4, and metal film can be gold, silver, aluminium, copper, nickel, the chromium film is formed capacitive element, and its capacitance is 7PF to 85PF.The skirt section metal face 9 of insulating ceramic 2 is connected through the metal shell 4 of small sealing ring 8 with band lateral electrode 5, forms a utmost point.The center hole wall metal film face 3 of insulating ceramic 2 is connected to form another utmost point through conducting resinl 6 and conductive lever 1.
The skirt section of the insulating ceramic 2 of self-tolerant spark plug and center bore inner wall metal-coated membrane, by after the PROCESS FOR TREATMENT, central electrode 7, conducting resinl 6, conductive lever 1 is packed in turn from the centre bore of insulating ceramic 2.By after the PROCESS FOR TREATMENT, again small sealing ring 8 is installed on the skirt section of insulating ceramic 2, pack in the metal shell 4 by technological requirement, be put on the machine behind 11 riveteds of metal shell 4 ends.
The self-tolerant spark plug, actual measurement shows, but every kilometer fuel-economizing 5% to 15%, increase power 8% to 18%, tail gas enters purifying rate and improves 30% to 50%, simultaneously, cold start is triggered at any moment, acceleration is good, can reduce the carbon distribution of combustion knock and combustion chamber, spark plug, prolongs petrol engine useful life.The utility model is easy for installation, without any need for maintenance and maintenance.
Claims (2)
1. self-tolerant spark plug, comprise conductive lever (1) and central electrode (7), conducting resinl (6), insulating ceramic (2), the metal shell (4) of band lateral electrode (5), small sealing ring (8), it is characterized in that, the skirt section of insulating ceramic (2) and its center hole wall be metal-coated membrane respectively, form capacitive element, the metal face (9) in the skirt section of insulating ceramic (2) is connected with metal shell (4) through small sealing ring (8), and the center hole wall metal film face (3) of insulating ceramic (2) is connected with conductive lever (1) through conducting resinl (6).
