FIELD: engines and pumps.
SUBSTANCE: internal combustion engine combustion chamber limited by a piston bottom, a cylinder head and provided with a heat-insulating ceramic coating on which a heat-accumulating and heat-transfer layer is applied made of high-temperature metal with high metal heat capacity, which one surface is in contact with working gases, coated with a layer of high heat-conducting metal, the other one is in contact with the heat-insulating ceramic layer provided with a heat reflector, in this case, the ribs made of material with shape memory effect are arranged on the surface of the high-heat-conducting metal layer.
EFFECT: improved reliability of diesel start-up with a complicated multi-layer heat-insulating coating.
