SPARK PLUG AFFORDING CONSIDERABLE REDUCTION OF FUEL-AIR MIXTURE COMBUSTION TIME IN INTERNAL- COMBUSTION ENGINES

摘要

FIELD: internal-combustion engines using electric fuel ignition. SUBSTANCE: spark plug designed for use in internal-combustion engines has metal body, electrodes, and insulator separating them; length of electrodes protruding to combustion chamber is close to or greater than cylinder radius; plug electrodes are hollow structures with cooling agent such as air passed through them. EFFECT: reduced combustion time of fuel-air mixture; enhanced engine efficiency and economic efficiency 1 cl, 4 dwg .
