Abstract
A kind of automobile spark plug, comprise housing, housing is provided with lateral electrode, housing upper is provided with retaining thread, retaining thread lower end is provided with hexagonal spiral, and also comprise central electrode and be positioned at the insulating material between described central electrode and housing, retaining thread upper end is provided with extension; Outward-dipping formation inclined-plane, extension upper surface, lateral electrode is located on described inclined-plane.During the utility model igniting, oil gas causes Mars by central electrode and lateral electrode most proximal end, outwards expand in a flash after gas mixture is ignited, form air-flow from inside to outside, this strand of air-flow is expanded outwardly by center, the gas mixture that will be collected on spark-plug body is blown off, and this strand of air-flow can effectively prevent not clean-burning material to be collected at spark-plug body upper end.
Description
Technical field
The utility model relates to a kind of automobile spark plug.
Background technology
Current spark plug on the market mainly utilizes lateral electrode and central electrode to strike sparks and produces spark to ignite the oil gas in combustion chamber.But not clean-burning material can be produced in oil gas ignition process, it is easily bonded on spark-plug body, and current common spark plugs housing upper end is that the not clean-burning material of plane is bonded in after on housing and easily gathers, and finally causes lighting a fire.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of not clean-burning material can not be bonded on housing
The technical scheme in the invention for solving the technical problem is: a kind of automobile spark plug, comprise housing, described housing is provided with lateral electrode, described housing upper is provided with retaining thread, described retaining thread lower end is provided with hexagonal spiral, the insulating material also comprising central electrode and be positioned between described central electrode and housing, described retaining thread upper end is provided with extension; Outward-dipping formation inclined-plane, described extension upper surface, described lateral electrode is located on described inclined-plane.
Further, for ensureing the efficiency optimization of product, described bevel inclination angle is 15 degree to 35 degree.
Further, too high for ensureing product work temperature, be provided with cooling ring between described retaining thread and hexagonal spiral.
The beneficial effects of the utility model are: during igniting, oil gas causes Mars by central electrode and lateral electrode most proximal end, outwards expand in a flash after gas mixture is ignited, form air-flow from inside to outside, this strand of air-flow is expanded outwardly by center, the gas mixture that will be collected on spark-plug body is blown off, and this strand of air-flow can effectively prevent not clean-burning material to be collected at spark-plug body upper end.
Accompanying drawing explanation
Fig. 1 is the utility model end view.
Fig. 2 is the utility model stereogram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As illustrated in fig. 1 and 2: a kind of automobile spark plug, comprise housing 1, described housing is provided with lateral electrode 2, described housing 1 top is provided with retaining thread 3, described retaining thread 3 lower end is provided with hexagonal spiral 4, also comprise central electrode 5 and be positioned at the insulating material 6 between described central electrode 5 and housing 1, described retaining thread upper end is provided with extension 7; Outward-dipping formation inclined-plane 8, described extension 7 upper surface, described lateral electrode 2 is located on described inclined-plane 8.
Further, for ensureing the efficiency optimization of product, angle of inclination, described inclined-plane 8 is 15 degree to 35 degree.
Further, too high for ensureing product work temperature, be provided with cooling ring between described retaining thread and hexagonal spiral.
The beneficial effects of the utility model are: during igniting, oil gas causes Mars by central electrode and lateral electrode most proximal end, outwards expand in a flash after gas mixture is ignited, form air-flow from inside to outside, this strand of air-flow is expanded outwardly by center, the gas mixture that will be collected on spark-plug body is blown off, and this strand of air-flow can effectively prevent not clean-burning material to be collected at spark-plug body upper end.
