INTERNAL COMBUSTION ENGINE Russian patent published in 2018 - IPC F02B75/04 F02B75/32 

FIELD: motors and pumps.

SUBSTANCE: invention relates to an internal combustion engine with a variable compression ratio mechanism. When the stop portion is brought into contact closely with stop portion (35) on the high compression side of the housing, when viewed in the axial direction of the control shaft, the configuration is performed, so that the distance between stop surface (42) on the high compression side of the housing and stop surface (40) on the high compression side of the control shaft becomes relatively longer, when it is closer to the center of control shaft rotation. Similarly, when the stop portion is brought into contact closely with stop portion on the low compression side of the housing, when viewed in the axial direction of the control shaft, distance between the stop surface on the low compression side of the housing and the stop surface on the low compression side of the control shaft becomes relatively longer when it is closer to the center of control shaft rotation.

EFFECT: technical result is the prevention of the load, which is formed in both stop portions.
