FIELD: mechanical engineering; piston machines.
SUBSTANCE: according to invention, rods made of non-ferrous metal or alloy are fitted flush, with guaranteed interference, in through radial holes of cylinder liner walls. Rods are arranged in rows along liner generatrixes in staggered order relative to each other. Sides of ends of lower rods pointed inwards liner are overlapped by sides of above rods. Invention is aimed at providing uniform distribution of non-ferrous metal or alloy separated from rods by friction of piston rings over entire surface of liner at relatively simple design and increased heat transfer from combustion chamber into cooling jacket owing to opening of rods made of non-ferrous metal or alloy into cooling jacket.
EFFECT: improved cooling of engine cylinders.
