Abstract
The utility model discloses a motor spark plug. The motor spark plug comprises a central electrode, a side electrode, an insulator and a case, wherein the case wraps the lower middle part of the insulator; the insulator wraps the central electrode; the upper end of the central electrode protrudes out of the top end of the insulator; the side electrode is arranged on the top end of the case; the central electrode has a conical top end; a booster electrode is arranged between the central electrode and the side electrode and located on the top end of the insulator. The motor spark plug provided by the utility model is more powerful and convenient in ignition, can ensure full combustion of fuels to generate large energy, and is unlikely to cause carbon deposition on the electrode, thereby improving the work performance of motor.
Description
Technical field
The utility model relates to a kind of engine, particularly a kind of engine spark plug.
Background technology
Existing spark plug comprises housing; Be arranged on the insulator in the housing and be arranged on the central electrode in the insulator; Top at housing is provided with lateral electrode, and lateral electrode and central electrode are relative, when between central electrode and the lateral electrode electrion being arranged; Then can between two-stage, produce spark, then the fuel in the ignition engine combustion chamber.Existing spark plug can only be lighted a fire by single-point between central electrode and lateral electrode, and the spark that is produced is little, fully fire fuel; Cause fuel combustion insufficient, single-point igniting is carbon distribution on electrode easily also, is the plug ignition failure; And the central electrode of existing spark plug is cylindrical; Lateral electrode is a cuboid, according to the point discharge principle, two near the facet metal object between discharge sparking not as two near most advanced and sophisticated metal object between the discharge sparking strong and powerful.
Summary of the invention
The purpose of the utility model just is to provide a kind of igniting stronger, quick, can make full combustion of fuel, and be difficult for the engine spark plug of carbon distribution on the electrode.
To achieve these goals; The technical scheme that the utility model adopts is such: the engine spark plug of the utility model, comprise central electrode, lateral electrode, insulator and housing, and housing is coated on the middle and lower part of insulator; Insulator is coated on the central electrode; The insulator top is stretched out in the central electrode upper end, and lateral electrode is arranged on the housing top, and it is conical that the top end of said central electrode is; Between central electrode and lateral electrode, be provided with an afterburning electrode, afterburning electrode is arranged on the insulator top.
As preferably, said afterburning electrode tilts to central electrode from bottom to top.
Compared with prior art, the advantage of the utility model is: the top end of central electrode is conical, has improved the operating efficiency of igniting; And be difficult for carbon distribution on the electrode, between central electrode and lateral electrode, be provided with an afterburning electrode, owing to be provided with afterburning electrode; Form the multi-point spark situation between afterburning electrode and the lateral electrode; The energy that produces is big, can make full combustion of fuel, and then improves the service behaviour of engine.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1, the engine spark plug of the utility model comprises central electrode 1, lateral electrode 4, insulator 2 and housing 3; Housing 3 is coated on the middle and lower part of insulator 2; Insulator 2 is coated on the central electrode 1, and insulator 2 tops are stretched out in central electrode 1 upper end, and lateral electrode 4 is arranged on housing 3 tops; It is conical that the top end of said central electrode 1 is; Between central electrode 1 and lateral electrode 4, be provided with an afterburning electrode 5, afterburning electrode 5 is arranged on insulator 2 tops, and said afterburning electrode 5 tilts to central electrode 1 from bottom to top.
It is conical that the top end of central electrode 1 is, and improved the operating efficiency of igniting, and be difficult for carbon distribution on the electrode; Between central electrode 1 and lateral electrode 4, be provided with an afterburning electrode 5; Owing to be provided with afterburning electrode 5, form the multi-point spark situation between afterburning electrode 5 and the lateral electrode 4, the energy of generation is big; Can make full combustion of fuel, and then improve the service behaviour of engine.The utility model can strengthen spark gap under the situation that does not improve pulse voltage; Promptly strengthen the distance between central electrode 1 and the lateral electrode 4; Strengthened discharge effect, ignition performance is improved, afterburning electrode 5 is arranged between middle electrocardiograph and the lateral electrode 4; Can in the spark plug confined space, further increase spark gap, thus further enhanced discharge effect.
