The composition and principle of spark plug plug the composition of the spark plug is composed of dielectric and metal shell of two parts: metal shell with screw thread, screw in cylinder depends on it;
In the casing is equipped with an insulator, it through with a central electrode, upper center electrode connection nut, high-voltage wire connection from distributor plate;
Under the shell of the transverse welding has grounding electrodes, the center between the electrode and the grounding electrode is 0.
0 mm gap, high voltage, after the clearance will burst out sparks mixture into the ground.
Working principle of spark plug ignition device of high voltage between the center of the spark plug electrode and the electrode, making them between the gas ionization, the insulation between the electrodes are destroyed and generate an electric current, spark discharge is generated.
Caused by electric spark ignition is through the spark discharge between the electrode and make the combustion particles activeness, and heating effect occur, flame kernel formation, the final form in itself as the center to the peripheral expansion flame combustion.
