Abstract

The utility model relates to a sparking plug capable of improving the ignition efficiency, which is provided with an insulation porcelain body, a cap nut fixed on the bottom end of the insulation porcelain body, an outer thread part positioned at the top part of the insulation porcelain body, a central electrode projected out of the top end, and a suspended type ground electrode which is climbed to above the central electrode form the top end of the outer thread part and is corresponding to the central electrode in a spacing way. The utility model is characterized in that the ground electrode is provided with a through hole which can communicate the inner surface with the outer surface; by the formation of the through hole, the local part of outer surface of the central electrode can be communicated with the outside via the through hole, and the ignition spark can be spread out in a radial shape; the spark intensity can be improved, and the combustion efficiency can be improved thereby.

Description

A kind of spark plug

Technical field

The utility model relates to a kind of spark plug, and is particularly a kind of by through hole is set on grounding electrode, to help conflagration and to reduce the spark plug of the ignition effectiveness promoted of carbon distribution speed.

Background technology

Commercially available spark plug label is various, the pattern inequality, and comprehensively the spark plug of each label is as can be known, it is formed with general insulating ceramic, the assemblies such as bolt, external screw thread, contre electrode and grounding electrode of getting angry, just, general spark plug and vaporized lpg contact area are little, and ignition efficient is lower, make thoroughly combustion explosion of oil gas, reduce explosive thrust, engine horsepower can't be brought into play, and accumulate Residual oil easily, cause secondary surplus quick-fried, increase shortcomings such as noise and air pollution.

As shown in Figure 1, 2, 3, a kind of existing spark plug 1, have external thread part 13, that nut 12, that an insulating ceramic 11, is fixed in these insulating ceramic 11 bottoms is positioned at these insulating ceramic 11 tops and protrude from the contre electrode 14 on top, and one climb from these external thread part 13 tops and to rise to these contre electrode 14 tops and to be corresponding at interval cantilever-shaped grounding electrode 15 with it.

Existing spark plug 1, because this contre electrode 14 is all dull and stereotyped surface with grounding electrode 5, and be parallel arranged side by side, so, when high-tension current is outwards disengaged by this contre electrode 14, because it is closely corresponding and produce an amount of spark 16 with this grounding electrode 15, this spark 16 from the tip of this contre electrode 14 or outer surface to around launch, directly impact grounding electrode 15, the planar surface 151 of the grounding electrode 15 of close this contre electrode 14 has hindered the scattering of this spark 16, and be only limited to a side that burns the combustion chamber and the below of causing the grounding electrode back side, and the oil of side can't burn moment, burning rate is slow, oil gas can't be burnt up hill and dale, reduce explosive thrust, engine horsepower also can't effectively be brought into play, and accumulate Residual oil easily, also can cause secondary surplus quick-fried, increase noise pollution, add incomplete combustion, the toxic gas volume that produces carbon monoxide and carbon compound is than improving, cause air pollution, and quicken to produce the speed of a large amount of carbon distributions 17, the generation igniting is undesired, must often remove and could continue to use, increase the puzzlement in many uses on foot, quite impracticable.

The utility model content

It is a kind of by at grounding electrode through hole being set that the purpose of this utility model is to provide, and helped conflagration and reduce the spark plug of the ignition effectiveness promoted of carbon distribution speed.

The spark plug of promoting ignition effectiveness of the present utility model, be used on the engine of vehicle, this spark plug has insulating ceramic, be fixed in the nut of this insulating ceramic bottom, be positioned at the external thread part at this insulating ceramic top, protrude from the contre electrode on top, and climb from this external thread part top and to rise to this contre electrode top and to be the grounding electrode of corresponding at interval suspention shape with it, it is characterized in that: this grounding electrode has the through hole that inner surface is communicated to outer surface, by the formation of this through hole, make that the outer surface of this contre electrode is local to be seen through this through hole and be in communication with the outside.

Description of drawings

Below by most preferred embodiment and accompanying drawing the spark plug of promoting ignition effectiveness of the present utility model is elaborated, in the accompanying drawing:

Fig. 4 is a stereogram, illustrates that the utility model can promote the preferred embodiment of the spark plug of ignition effectiveness;

Fig. 5 is a sectional perspective enlarged drawing of this preferred embodiment;

Fig. 6 is a part sectioned view of this preferred embodiment, the blast state of spark when igniting is described;

Fig. 7 is a local combination section of this preferred embodiment.

Embodiment

Consult Fig. 4,5, shown in 7, the preferred embodiment that the utility model can be promoted the spark plug 2 of ignition effectiveness is to be used on the engine of vehicle, this spark plug 2 has an insulating ceramic 21, one is fixed in the nut 22 of these insulating ceramic 21 bottoms, one is positioned at the external thread part 23 at these insulating ceramic 21 tops, one protrudes from the contre electrode 24 on top, and one climb from these external thread part 23 tops and to rise to these contre electrode 24 tops and to be the grounding electrode 25 of corresponding at interval suspention shape with it, this grounding electrode 25 has the through hole 253 that inner surface 251 is communicated to outer surface 252, by the formation of this through hole 253, make that the outer surface 241 of this contre electrode 24 is local to be seen through this through hole 253 and be in communication with the outside.In this case preferred embodiment, this through hole 253 is shaped as narrow outer wide upside-down triangle shape in.

Consult shown in Figure 6, during use, when this contre electrode 24 flows into high-tension current via high-tension ignition coil, and produce an amount of spark 26 with this grounding electrode 25, towards grounding electrode 25 scatterings, at this moment, because of the through hole 253 of this grounding electrode 25 be set as in narrow outer wide del (see figure 7), so, help this spark 26 to be radiation and evenly scatter out, to increase spark intensity, promote burning rate, and strengthen the thrust of exploding, help the piston rapid movement, and drive in-engine crank rotation (figure does not show), produce revolution inertia force, improving outputting torsion, and can improve the acceleration of vehicle, in addition, because of its burning area increases, institute is so that oil gas is burnt more to become fully, and the carbon monoxide and the carbon gasification compound toxic gas that can reduce in the waste gas produce, and make air pollution reduce to bottom line.

Secondly, because this grounding electrode 25 of this case is provided with through hole 253, the carbon ash that is produced when helping ignition passes through this through hole 253 by powerful scattering strength, and with radial quick eliminating, effectively reduce carbon distribution speed, the puzzlement of decarbonizing and inconvenience when using to reduce, and also can safeguard that spark plug 2 normal ignitions use simultaneously, with the practical advantage that increases the service life, so can reach the purpose of this utility model really.
