Abstract
The utility model provides a holed spark plug, comprising a center electrode and a lateral electrode. The holed spark plug is characterized in that the discharging end of the center electrode is provided with a hole that is concave inward, and the position of the lateral electrode is corresponding to the discharging end of the center electrode and is provided with a through hole. The holed spark plug can make the spark plug easily discharge and jump spark, the spark energy is sufficiently releases and utilized, the strong burning capacity is formed, and the gas mixture can be easily ignited within the large air-fuel ratio range. Meanwhile, the quenching effect is farthest reduced, the self-purification temperature of the spark plug is stabilized, the explosion is suppressed, the service life of the spark plug is effectively prolonged, the stable and reliable working performance of the spark plug is ensured, and therefore the holed spark plug is an ideal spark plug for engine ignition.
Description
Technical field
The utility model provides a kind of spark plug, especially a kind of high-performance spark plug that is used for engine ignition.
Background technology
Usually when ato unit, all to use spark plug that it is lighted a fire.But the spark plug that uses exists many deficiencies or drawback mostly at present, and what have causes spark plug to light a fire because of being difficult for the discharge arcing; What have increases quenching effect because of having compressed discharge spark too much, directly influences the igniting usefulness of spark plug.Therefore, be necessary prior art is improved.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of igniting usefulness height is provided, and spark energy discharges big and energy-conservation environment-friendly type Holed spark plug.
The utility model is finished by following technical proposal: a kind of Holed spark plug, comprise central electrode and lateral electrode, and it is characterized in that the discharge end at central electrode is provided with the hole of indent, be provided with through hole in the position of the corresponding central electrode discharge end of lateral electrode.
The inside recess of described central electrode discharge end is circular pit or square hole or triangle, polygon hole, or the inside recess of other shape, so that effectively increase the space of scattering of discharge spark, improves the release of spark energy, guarantees that igniting carries out smoothly.
Through hole on the described lateral electrode is relative with the pit of central electrode discharge end, this through hole is the hole of circular port or square opening or triangle, polygonal hole or other shape, so that the transmission of spark energy reduces quenching effect to greatest extent, suppress detonation, the useful life of extending plug.
The utility model compared with prior art has following advantage and effect: adopt such scheme; make the easier discharge arcing of spark plug; fully discharge and utilize spark energy; make it to form stronger burning capacity; in bigger air-fuel ratio scope, light gaseous mixture easily; reduce simultaneously quenching effect to greatest extent; stablize the burn-off temperature of spark plug; suppress detonation; the useful life of effective extending plug; guaranteeing the service behaviour that spark plug is reliable and stable, therefore, is a kind of comparatively ideal engine igniting spark plug.
