Chemical reactions which are accompanied by light and heat phenomena are generally called flames. Considered elementarily, the "fuel" reaction partner has electrostatic valent charges which exert force on the "oxygen" reaction partner. Above a specific temperature, both materials have sufficient movement energy to shear existing bonds, to follow the electrostatic charge and to start the flame reaction. The subject-matter of the invention is to neutralise (saturate) the elementary charge asymmetry by means of an external electrical field. The higher the electrical field strength applied to the flame to be influenced is selected to be, the greater the number of fuel particles which lose their reaction tendency and the weaker the flame becomes. Applications of the idea according to the invention: - controlling the rate of ignition in Otto-cycle or diesel engines, - extinguishing fires with liquid, solid or gaseous electrodes, - protecting combustible materials against ignition, - controlling the flame intensity of furnace burners and keeping the flame away from the wall of the furnace, - obtaining soot by forced interruption of the reaction. The drawing shows an electrode arrangement for preventing detonation combustion in an Otto-cycle and diesel engine. <IMAGE>
