SPARK PLUG, FIRST AND FOREMOST FOR OPERATION UNDER HIGH PRESSURE CONDITIONS IN COMBUSTION CHAMBER

摘要

FIELD: electricity.;SUBSTANCE: spark plug comprises an insulator (3), inside of which there is a central electrode (4), and a body (2), which at least partially covers the insulator (3). On the insulator (3) there is a current-conducting thin-layer element (7), which electrically contacts with the body (2) of the spark plug.;EFFECT: prevention of surface spark discharges even during high pressure pulling in the combustion chamber.;12 cl, 2 dwg
