METHOD FOR TREATMENT OF PISTONS OF INTERNAL COMBUSTION ENGINES MADE OF ALUMINIUM, TITANIUM AND THEIR ALLOYS Russian patent published in 2012 - IPC C25D11/08 C25D11/26 F02F3/12

Abstract RU 2439211 C1

FIELD: electricity.

SUBSTANCE: method includes oxidation of piston bottom in electrolytic solution based on orthophosphoric acid by means of simultaneous piston motion in regard to free surface of electrolyte so far as coating is formed at piston bottom; at that the opposite side is cooled by compressed air.

EFFECT: method allows reduction of specific fuel rate, increase of effective power and effective efficiency of engine, increase average effective pressure of operating cycle and reduce toxicity of exhaust gases.
