Abstract
The utility model relates to an improved spark plug. The improved spark plug comprises a grounding nut, an insulator, a central electrode and a shell, wherein the shell is connected with a side electrode; the side electrode comprises an arc surface arranged by extending upwards along the upper end of the shell; more than one circular hole is opened in the arc surface; and the circular hole is formed in the same radial plane. According to the improved spark plug disclosed by the utility model, the side electrode is formed to be the arc surface with the circular hole, thus increasing ignition efficiency, improving heat-conducting performance, increasing air ventilation, and reducing carbon deposition.
Description
Technical field
The utility model relates to a kind of spark plug.
Background technology
Conventional ignition plug in using both at home and abroad at present, great majority are single central electrode and single-sided electrode structure.The discharge end of this spark-plug side electrode turn of bilge, cover centering electrode top, thereby covered electric spark, be unfavorable for that electric spark removes in the efficient solution of combustion mixture maximum, the electrode structure of this protected type, sparking-plug electrode part electric spark is produced to the moment expansion of right flame of wink, form and cover and the flame arrest effect, weaken electric spark electric heating energy.In addition, this spark-plug side electrode is too narrow, to such an extent as to heat conductivility is not fine, after the long-term igniting of spark plug, burning phenomenon easily occurs.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of spark plug that can avoid flame arrest and improve heat conductivility.
The technical scheme in the invention for solving the technical problem is:
A kind of improved sparking plug, comprise grounding nut, insulator, central electrode and housing, housing is connected with lateral electrode, and described lateral electrode comprises the cambered surface that extends upward setting along the housing upper end, offer more than one circular hole on cambered surface, described circular hole is arranged in same sagittal plane.
As preferably, be provided with threaded portion on housing, axially be provided with more than one cleaning groove on threaded portion, the cleaning groove runs through and is arranged on described threaded portion outer surface.
As preferably, clear up groove and be provided with 3.
Lateral electrode is arranged to along the millet cake fire, and lateral electrode is a cambered surface, has increased like this lateral electrode area, ignition effectiveness is higher, has increased heat conductivility, and circular hole is set on cambered surface, circular hole becomes steam vent, increases circulation of air, makes spark energy be delivered in gaseous mixture and go rapidly.Axially run through the cleaning groove is set at the threaded portion of housing outer surface, when screwing in corresponding internal thread, can effectively remove the dirt that threaded connection place retains, the problem of arc control plug ablation.
The beneficial effects of the utility model are: the utility model is set to the round-meshed cambered surface of tool by lateral electrode, has not only increased ignition effectiveness and has increased heat conductivility, and increased circulation of air, reduces coking.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of improved sparking plug, comprise grounding nut 7, insulator 6, central electrode and housing 5, housing 5 is connected with lateral electrode, described lateral electrode comprises the cambered surface 1 that extends upward setting along the housing upper end, offer more than one circular hole 2 on cambered surface 1, circular hole 2 is arranged in same sagittal plane.Be provided with threaded portion 4 on housing, axially be provided with more than one cleaning groove 3 on threaded portion 4, cleaning groove 3 runs through and is arranged on described threaded portion 4 outer surfaces.The cleaning groove is provided with 3.
Lateral electrode is arranged to along the millet cake fire, and lateral electrode is a cambered surface 1, has increased like this lateral electrode area, ignition effectiveness is higher, has increased heat conductivility, and circular hole 2 is set on cambered surface 1, circular hole becomes steam vent, increases circulation of air, makes spark energy be delivered in gaseous mixture and go rapidly.Axially run through cleaning groove 3 is set at the threaded portion of housing outer surface, when screwing in corresponding internal thread, can effectively remove the dirt that threaded connection place retains, the problem of arc control plug ablation.
The utility model is set to the round-meshed cambered surface of tool by lateral electrode, has not only increased ignition effectiveness and has increased heat conductivility, and increased circulation of air, reduces coking.
Claims (3)
