4 , Single side pole with multi-side spark plug

The conventional unilateral spark plug has a noticeable drawback that the side electrode covers the center electrode. When the high-voltage discharge between the two poles, the spark gap at the mixture will absorb the spark heat and ionization is activated to form a "fire nucleus." The location of the formation of the fire nuclei generally close to the side of the electrode, the heat will be more side electrode absorption, that is, the electrode "flame suppression effect", which reduces the spark energy,
The spark plug mechanism reduces the flashover performance.
Thus, in the 1920s, there were three sides of the spark plug. Compared with the unilateral pole, the spark gap of the multi-side pole is composed of a cross section of a plurality of side electrodes (round hole) and a cylindrical surface of the center electrode, and the side spark gap eliminates the fact that the side electrode covers the center electrode Shortcomings, increased sparks "reachability", spark energy larger, easier to deep into the cylinder, help to improve the combustion of combustion conditions and reduce emissions. As the multi-side pole provides a number of flashover channel, thus extending the service life, improve the reliability of the ignition. It must be pointed out that the moment of discharge can only be a channel flashover, it is impossible to jump at the same time the side of the pole. The high-speed photography of the discharge process proves this.
In the domestic spark plug model, the suffix letters (letters after the number of heat values) D, J, Q, respectively, said the double pole, three side pole, four side pole.

5 , Production Process

1, iron shell grinding: finished semi-finished products after grinding the shell, polished a variety of spark plug models of the hexagonal side.

2, the welding side of the electrode: polished after the top of the iron in the top of the need for welding side of the electrode.

3, grinding screw: grinding the required thread size and thread length.

4, pressing the number: pressed to build the number.
