Abstract

The utility model relates to a strong sparking plug used in the internal engine. The utility model compromises shell, insulator, grounding electrode at the lower end of shell and center electrode. Electrode is the alligatoring ring shape of inner hook, which can form the electric sparking plug arrayed in plural poles ring shape with the ends of center electrode. The strong sparking plug has strong ignition force and saves the oil consumption.

Description

Spark plug

The utility model relates to the spark plug that a kind of internal combustion engine is used, particularly a kind of spark plug.

In the prior art, the spark plug used of internal combustion engine generally includes the grounding electrode and the central electrode of housing, insulator, housing lower end.Its grounding electrode generally is single the clubfoot that is welded in the housing lower end, and its igniting dynamics is not strong, causes in the cylinder atomization gas fully not burn and oil consumption is higher and the exhaust pollution environment is more serious.

The purpose of this utility model is to provide a kind of spark plug, improves the igniting dynamics and reduces engine oil consumption rate and exhaust pollution.

For achieving the above object, the utility model adopts following technical proposals:

A kind of spark plug comprises the earth electrode and the central electrode of housing, insulator, housing lower end, it is characterized in that grounding electrode is the electric spark clearance that the not end of the ring gear body of inwardly crotch and central electrode constitutes the radial multi-pole annular array.

The utility model compared with prior art, have following conspicuous characteristics and advantage: the utility model expands to the electric spark clearance of spark plug in the prior art electric spark clearance of multipole annular array, thereby greatly improve the igniting dynamics, reduce oil consumption rate and exhaust pollution.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is the profile at A-A place among Fig. 1.

Embodiment: referring to Fig. 1 and 2, this spark plug, the grounding electrode 3 and the central electrode 1 that comprise housing 2, insulator 5, housing lower end, grounding electrode 3 is the ring gear body of inside crotch and the electric spark clearance of the not end formation radial multi-pole annular array of central electrode 1.Grounding electrode 3 is that the annular solid radial cuts by housing 2 lower ends goes out 6～16 slits 4 and constitutes.

Claims

A kind of spark plug, the grounding electrode (3) and the central electrode (1) that comprise housing (2), insulator (5), housing lower end is characterized in that grounding electrode (3) is the ring gear body of inside crotch and the electric spark clearance of the not end formation radial multi-pole annular array of central electrode (1).
