Abstract
The utility model discloses a high-energy spark plug and consists of a conductive screw rod, a central electrode, a conductive adhesive, a metal shell with lateral electrode, a small sealed ring and an insulation ceramic body. The internal surface and the external surface of the metal shell are coated with metal membrane. The utility model has the beneficial effect that the production process is simpler, the coating surface is uniform and firm, the components are closely contacted with each other, with work stability and long service life. The trial has confirmed that the utility model has high efficient and reliable performance.
Description
Affiliated technical field
The utility model relates to a kind of high-energy sparking plug, belongs to gasoline engine spark plug parts.
Background technology
It is not strong that gasoline engine spark plug in the past mostly exists the electrical breakdown spark energy, the gasoline atomizing gas firing is insufficient, excessive fuel consumption and exhaust emissions are not smooth, often can cause cold start poor, the easy carbon distribution of combustion chamber and spark plug, cause engine problems such as overheated to occur, thereby have the people in spark plug, be provided with in electric capacity ZL99249479.6 self-tolerant spark plug not only in spark plug, be provided with interior electric capacity, and electric capacity made self-tolerant, promptly, form capacitive element at skirt section and its center hole wall difference metal-plated membrane of insulating ceramic 2.The structure of this design spark plug more in the past is compact more, has reduced cost, has improved the spark plug operating efficiency, but weak point is an electroplating technology trouble on insulating ceramic, and coating is firm inadequately, and the interelement contact requires also very high.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of technology simpler, and coating is firm, the high-energy sparking plug that interelement contacts.
Modular construction of the present utility model is similar to ZL99249479.6, all be that metal shell, small sealing ring and insulating ceramic by conductive lever, central electrode, conducting resinl, band lateral electrode constitutes, different technical schemes be that metal film is to be plated on the surfaces externally and internally of metal shell.
The beneficial effects of the utility model are: manufacture craft is easier, and coating is even, firm, and contact is close between the element, working stability, and long service life is through trying out confirmation, performance high efficient and reliable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is the utility model schematic appearance
Fig. 2 is each parts packing figure
Embodiment
As shown in Figure 1 and Figure 2, high-energy sparking plug is by conductive lever 1, central electrode 7, and conducting resinl 6, insulating ceramic 2, the metal shell 4 of band lateral electrode 5, small sealing ring 8 constitutes, band lateral electrode 5 metal shells 4 among Fig. 2, and 2 of insulating ceramics are in not riveted state.Metal film 3 and outer metal film 9 in being coated with respectively on metal shell 4 surfaces externally and internallies of band lateral electrode 5 make the outer metal film 9 and the interior metal film 3 of the metal shell 4 of band lateral electrode 5 form a utmost point, conducting resinl 6 and conductive lever 1 another utmost point of formation.Metal membrane material can be gold, silver, aluminium, copper, nickel, chromium etc.Its material and thickness can be set as required.
Claims (1)
1, high-energy sparking plug, by conductive lever, central electrode, conducting resinl, insulating ceramic, the metal shell of band lateral electrode, small sealing ring constitutes, it is characterized in that: the band lateral electrode (5) metal shell (4) surfaces externally and internally on be coated with respectively interior metal film (3) and outside metal film (9), metal membrane material can be gold, silver, aluminium, copper, nickel, chromium.
