Abstract
The utility model relates to a gasoline engine spark plug which comprises a central electrode, a grounding electrode and a porcelain slice, wherein, a spark ring which is made of a tungsten wire is arranged at the end part of the spark plug. A first structure of the spark ring is formed by a spring-shaped annular component which is vertically and continuously surrounded, and one end of the spring-shaped annular component is fixedly arranged at the end part of the spark plug; a second structure of the spark ring is formed by an annular component which is transversely and continuously surrounded, and the two ends of the annular component are respectively and fixedly arranged at the end parts of the spark plug. The tungsten-wire spark ring that is arranged on an electric discharge machine ensures the interior of an engine to send out high heat (1260 DEG C), when a piston draws back, the fuel in a cylinder is heated, so as to ensure that the internal fuel in a gasifying state is gasified to be more detailed, and the fuel can be easily and fully burnt by 100 percent during explosion, thereby reducing harmful discharged gases and environmental pollution.
Description
Technical field
The utility model relates to a kind of gasoline motor spark plug.
Background technology
Chinese patent 200620066545.3 has been announced a kind of " the thin electrode spark plug of annular ".Its purpose provides the thin electrode spark plug of a kind of annular, its diameter is the precious metal sheets that small center's electrode ignition end of 1.2-1.8mm is welded with thick 1-1.2mm, it is circular that annular external electrode is, there is the spill grooving inboard, the internal and external electrode surface area is corresponding to be reduced, thereby has reduced the flame arrest effect of electrode, and flame nuclear shoots up, lean mixture is fully burnt, reach the purpose of waste gas purification and reduction oil consumption.Its technical scheme is that the thin electrode spark plug of annular is made up of small center's electrode, annular external electrode, seal washer, iron-clad, electro-conductive glass glue, insulating ceramic, wiring screw rod, wiring nut, but the ring-type arcing, and export license is little, requirement voltage is low, ignition duration is long, and the effect of electrode flame arrest is little, and flame nuclear shoots up, lean mixture is fully burnt, improve power, reduced pollution, reduced oil consumption, thermal diffusivity is good, and manufacturing process is simple, durable.Its weak point is: the oil inflame rate is lower, and it is insufficient to burn.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, a kind of tungsten filament spark ring of installing on the spark machine of gasoline engine is provided, make engine interior send high heat (1260 degree), when piston retreats, fuel in its cylinder is heated, and is the finer and closely woven gasification of the fuel of inner vaporized state, easier of the complete fuel in fuel 100% ground during outburst, reduce harmful exhaust mist, reduced the gasoline motor spark plug of environmental pollution.
The purpose of this utility model can reach by following measure:
This gasoline motor spark plug comprises grounding electrode, central electrode and ceramics, and its special character is: the end of described spark plug is provided with a spark ring by the tungsten filament making.
The purpose of this utility model can also reach by following measure:
Described spark ring is made up of the spring-like annular construction member of vertical continued circling; The one end is installed in the end of spark plug.
The cross section of described spark ring is circular.
The cross section of described spark ring is oval ring-type.
The cross section of described spark ring is the U-loop shape.
Described spark ring is made up of the annular construction member of horizontal continued circling; Its two ends are installed in the end of spark plug respectively.
To be that the U-shaped opening is positive and negative be staggered and the ring-type of continued circling in the longitudinal section of described spark ring.
The base angle of described U type is a vertical configuration, and promptly the base of U-shaped is parallel with the end cross-sectional of spark plug respectively, and the longitudinal edge of U-shaped is parallel to each other.
The longitudinal section of described spark ring is that parabolic shape is staggered and the ring-type of continued circling.
The longitudinal section of described spark ring is that semi-circular shape or semiellipse shape are staggered and the ring-type of continued circling.
The utility model has following advantage compared to existing technology:
1, improved the discharge standard of petrol engine combustion gas.
2, the petrol engine fuel gas buring is abundant, and its discharging meets environmental protection requirement more.
3, improved petrolic useful life.
