Abstract

The utility model discloses a spark plug with spray umbrella-shaped flame. The end head of a center electrode (9) is provided with a big disc electrode (10). The big disc electrode (10) and the center electrode (9) are connected together to form an inverted mushroom shape. The utility model has the advantages that the carbon deposit of the center electrode is reduced, the detonation of an engine is reduced, the compression ratio is enhanced, the oil consumption is reduced by more than 8%, the dynamic force is increased by more than 8%, the torsional moment is increased by 11.4%, the exhaust gas purification rate reaches more than 50%, the utility model can ignite in a sliding mode to form a big circular ring with 360 DEG, the utility model jets umbrella-shaped flame for combustion, when the temperature is below minus 25 DEG C, the utility model can be successfully started, the maximum vehicle speed can be improved by more than 10%, the accelerating ability is good and the service life can reach more than 40000 kilometers.

Description

Spray the umbrella-shaped flame spark plug

Affiliated field

The utility model relates to a kind of spark plug, particularly a kind of injection umbrella-shaped flame spark plug.

Background technology

The present employed spark plug of ignition system of internal combustion engine, as shown in Figure 1, the most basic element of forming is a housing 6, central electrode 9 and lateral electrode 11, its middle shell 6 and lateral electrode 11 are made one by welding, be insulator 2 between housing 6 and the central electrode 9, this spark plug has only place igniting, and the electrical breakdown spark is indifferent, and the gasoline atomizing gas firing is insufficient, excessive fuel consumption and exhaust emissions are not smooth, often can cause cold start poor., igniting is difficult for, and fuel consumption is bigger, burning is easy to carbon distribution, influence the useful life of spark plug, pinking also easily takes place in engine, and phenomenon such as engine overheat takes place.

Summary of the invention

The purpose of this utility model promptly is to overcome the shortcoming of prior art, and a kind of injection umbrella-shaped flame spark plug is provided, and it can light a fire in 360 ° of slips of large circle, reduces combustion knock, improves compression ratio, improves combustibility.

The purpose of this utility model is achieved through the following technical solutions: comprise the wiring nut, wiring screw rod, the conductor glass seal layer, central electrode, they link to each other successively, and insulator is wrapped in the outside of wiring screw rod, conductor glass seal layer and central electrode, be wrapped with housing in the insulator Lower Half, also be provided with upper gasket and lower gasket between insulator and housing, housing also has an external seal packing ring outward

Be provided with a big disk electrode in the central electrode termination, big disk electrode and central electrode are joined together to form an inverted mushroom.

By top narration as can be seen, the utlity model has following advantage: can reduce the central electrode carbon distribution, reduce combustion knock, engine running is steady, noise reduces, improve compression ratio, improve combustibility greatly, it can light a fire in 360 ° of slips of large circle, the burning of injection umbrella-shaped flame, through Xian Road Communication Univ., Beijing Internal-Combustion Engine General Factory's engine bench test shows: spark plug fuel consumption of the present utility model reduces more than 8%, and power increases more than 8%, and moment of torsion increases by 11.4%, the exhaust gas purification rate is more than 50%, kind of vehicle surplus 20, thousands of on probation shows that the utility model also has the following operating characteristic: can start smoothly below 25 ° subzero, the max speed can improve more than 10%, acceleration performance spy is good, the life-span speciality, the general life-span of common spark plug is 10000～20000 kilometers, and the utility model can reach more than 40000 kilometers.
