METHOD TO ENRICH ICE LUBRICATION SYSTEM OIL BY NON-FERROUS METAL ALLOYING ELEMENTS AND DEVICE TO THIS END (VERSIONS) Russian patent published in 2010 - IPC F01M9/02 

FIELD: engines and pumps.

SUBSTANCE: invention relates to machine building, namely engine production, and can be used in friction assemblies of machinery operated in various industrial branches. Method to enrich ICE lubrication system oil by non-ferrous metal alloying elements consists in exposing non-ferrous metal layer to oil effects. Note here that non-ferrous metal engine part is continuously dissolved by corrosion in lubrication system oil. Said engine part arranged in oil pan is isolated from pan case by gasket and connected in engine electric circuit as an anode. Device to enrich ICE lubrication system oil by non-ferrous metal alloying elements represents water-to-oil heat exchanger arranged in oil pan and incorporated with engine cooling system. Heat exchanger tubes, or one of them, are made from bronze or materials containing copper and zinc and permanently dipped in oil. Note here that outer surface of said tube is continuously washed by engine oil while tube inner surface of said heat exchanger is washed by circulating cooling fluid. In compliance with another version, proposed device represents additional part, an insert, made from non-ferrous metal and mounted on oil pan bottom part, e.g. drain plug, insulated from engine chassis and connected into engine electric circuit.

EFFECT: higher efficiency of enriching continuously ICE lubrication system oil by non-ferrous metal alloying elements.
