METALLIC SURFACE C BY DEEPENING, SUBSTITUTED HUMS IT BY LASER BEAM, FILLED WITH MATERIAL C BY LOW THERMAL CONDUCTIVITY; TWO-SHAFT CRANK; MECHANISM THE ENGINE OF INTERNAL COMBUSTION (TWO VERSIONS), WHEREIN THE B THE FIRST VERSION IS USED ONLY ABOVE-MENTIONED METALLIC SURFACE, AND IN THE SECONDARY VERSION ARE USED POINT OUT ABOVEED METALLIC SURFACE AND TWO-SHAFT CRANK MECHANISM

摘要

FIELD: engines and pumps.;SUBSTANCE: invention can be used in power converters incorporated with, for example, ICEs. Heat-exchange metal surface (1) has recesses (2) filled with material with heat conductivity lower than that of surface material (1). Recesses (2) are made by laser and feature the following sizes: diameter - 0.001-1 mm, depth - 0.2-10 of said diameters. Invention discloses design versions of engines, cylinder surfaces, those of pistons and their heads provided with heat-exchange metal surface (1) with recesses (2).;EFFECT: lower heat losses.;3 cl, 19 dwg, 1 tbl
