The Requirements For Voltage

SMALL DIAMETER OF THE SPARK PLUG CENTER ELECTRODE

Reducing the center electrode diameter results in concentrating electromagnetic field lines and achieving breakdown voltage earlier than with the thicker electrodes.

SMALL DIAMETER OF THE SPARK PLUG CENTER ELECTRODE AND CUT OF THE SPARK PLUG GROUND ELECTRODE

Reduction of the center electrode diameter and cut of the ground electrode to the center ensures concentration of electromagnetic field lines around both electrodes and results in achieving breakdown voltage at the lower voltage.

Reduction of the center electrode diameter and cut of the ground electrode to the shape of “A” ensures long edges and concentration of electromagnetic field lines around both electrodes and results in achieving breakdown voltage at the lower voltage.

REDUCED SPARK PLUG CENTER ELECTRODE AND CUT OF THE SPARK PLUG GROUND ELECTRODE

Use of the contact of the center electrode made of noble metal decreases wear and tear of the center electrode and enables use of a small diameter of the electrode. Reduction of the center electrode diameter and cut of the ground electrode to the center ensures concentration of electromagnetic field lines around both electrodes and results in achieving breakdown voltage at the lower voltage.
