THE FORMATION SURFACE OF THE ELECTRIC DISCHARGE OF THE SPARK PLUG "CASSINI"
The paper examines the possibility of increasing the surface of the electric discharge in the ignition devices of the working mixture of internal combustion engines. It is shown that the change of shape of the lower end of the Central electrode of the spark plug with a flat conductive "CASSINI ovals allows you to create the enhanced surface electric discharge in the form of a column volt with the cross-section in the shape of ovals of CASSINI", which creates the opportunity to increase spark gap, creating additional but two axes of the concentration of thermal energy and to increase the efficiency of ignition of the working mixture.
