FIELD: engines and pumps.
SUBSTANCE: present invention relates to ICE with variable compression degree. Mechanism (10) of variable compression degree, which changes engine compression ratio depending on angular position of first control shaft (14), and drive, which changes and holds angular position of first control shaft (14). Connecting mechanism connecting drive and first control shaft (14), has a lever (24) connected to first control shaft (14). Upper section of shoulder part (25), extending radially outward from centre of first control shaft (14), and one end of lever (24) are connected with possibility of rotation by first connecting pin (26). At least when installed on highest degree of compression, first connecting pin (26) is submerged below (α1) oil level of oil tray (6).
EFFECT: reduced wear of support part, improved lubrication, reduced values of noise and vibration.
