FORMATION OF THE SURFACE OF THE DISTRIBUTION OF THE INFLAMING SWEET IN THE FORM OF PARABOLIC CYLINDER

The paper analyzes the possibility of increasing the surface of the electric discharge in ignition devices of the working mixture of internal combustion engines. It is shown that the change of the shape of the bottom end of the central electrodes of the spark plugs from flat to parallel parabolic cylinders allows us to create an enlarged surface of an electric discharge in the form of pillars of voltages with a cross section, which gives an opportunity to increase the spark gap, create additional axis of concentration of thermal energy and simultaneously increase the efficiency of flammability of the working mixtures.
