FIELD: machine building.
SUBSTANCE: invention relates to machine building, namely to propulsion engineering. Internal combustion engine with variable compression ratio includes housing 1, cylinder 2, piston 3, guides 4 that prevent distortion of cylinder at movement, corrugated elastic seal 5, combustion chamber 6. Lower part of cylinder 2 is connected with corrugated elastic seal 5 to case 1. Corrugated elastic seal 5 is made from material with shape memory effect. At change of temperature of engine parts, martensitic conversion occurs in material of corrugated elastic seal, its crimps change their shape, thus changing height of corrugated elastic seal and moving cylinder 2 changing therein compression ratio of engine.
EFFECT: technical result is higher operation reliability and simplified design of engine.
