FIELD: motors and pumps.
SUBSTANCE: jacket of cylinder liner (1) of liquid-cooled internal combustion engine has an annular cavity (2) between the external surface of cylinder liner (1) and the walls (3) of the cylinder block, through which the cooling fluid circulates. In the cavity (2) a corrugated housing (4), forming with the external surface of the cylinder liner (1) a sealed camera (5), filled with heat-transfer fluid is located, the boiling temperature of which is higher, than the boiling temperature of the cooling fluid. The corrugated housing (4) is designed using the material with the shape memory effect.
EFFECT: minimising of cooling of the cylinder liner during start-up and warm-up of the motor.
