VARIABLE COMPRESSION CONTROL SYSTEM

摘要

The present invention is intended to facilitate installation of a variable compression control system in a vehicle and reduce the cost of said system. A variable compression control system 1 is provided with: an actuator unit 5 accommodated in a first area 41 within a housing 4 attached to an engine block having a control shaft for varying the compression ratio of an internal combustion engine, said actuator unit 5 allowing the rotation position of the control shaft to be varied; and a control unit 6 housed within a second area 42 separated from the first area 41 within the housing 4 by a partition wall 43, said control unit 6 controlling actuating of the actuator unit 5.
