Abstract

FIELD: sparking for ignition of combustible mixture in internal combustion engines, propulsion plants and power units. SUBSTANCE: insulator in lower part is manufactured in the form of hollow cylinder without central electrode, spiral groove is made in formed internal surface which sharp edges are ionization centers and are used as directing track for acceleration of charged particles of spark discharge which emerges between hole in insulator and side electrode. EFFECT: enhanced reliability and efficiency of ignition of working mixture, prolonged service life of sparking plug.

Изобретение относится к искровым свечам зажигания для воспламенения горючей смеси двигателя внутреннего сгорания, двигательных установок и энергоузлов. Цель изобретения - повышение надежности, эффективности, воспламенения рабочей смеси и увеличения долговечности свечи зажигания. Это достигается тем, что изолятор в нижней части выполнен в виде полого цилиндра без центрального электрода, а на образовавшуюся внутреннюю поверхность нанесена спиральная канавка, острые края которой являются центрами ионизации и служат направляющим треком для разгона заряженных частиц искрового разряда, который возникает между отверстием в изоляторе и боковым электродом.The invention relates to spark plugs for igniting a combustible mixture of an internal combustion engine, propulsion systems and power units. The purpose of the invention is to increase reliability, efficiency, ignition of the working mixture and increase the durability of the spark plug. This is achieved by the fact that the insulator in the lower part is made in the form of a hollow cylinder without a central electrode, and a spiral groove is applied to the formed inner surface, the sharp edges of which are ionization centers and serve as a guiding track for the acceleration of charged particles of the spark discharge that occurs between the hole in the insulator and side electrode.
