CYLINDER SLEEVE (VERSIONS) AND ENGINE

摘要

FIELD: engines and pumps. ^ SUBSTANCE: invention relates to engine production. Cylinder sleeve for casting with embedded elements used in producing cylinder block has multiple ledges on its outer peripheral surface. Every ledge features narrowed shape. Metal material film is formed on cylinder sleeve outer peripheral surface and ledge surfaces. Thermal conductivity of aforesaid film exceeds that of sleeve or cylinder block. Film extends axially from one edge of the sleeve to its center. Film thickness in sleeve upper part is smaller than that in its lower part. Invention covers internal combustion engine comprising described sleeve. ^ EFFECT: sufficient strength of sleeve-to-cylinder block joint and heat withdrawal into cylinder block. ^ 21 cl, 22 dwg
