SPARK PLUG Russian patent published in 1995 - IPC

FIELD: electric sparking devices. SUBSTANCE: spark plug has body with plasma chamber and central electrode which are separated by insulator. Surface of insulator, which forms spark gap, is arranged square to axis of plasma chamber. Offered design of spark plug makes it possible to increase its igniting capacity owing to the fact that plasmoid, moving along axis of plasma chamber, does not collide with side walls of combustion chamber and there are no losses of plasma motion kinetic energy. EFFECT: increased igniting capacity of spark plug. 1 dwg
