Abstract
Methods and systems are provided for a VCR engine. In one example, the VCR engine includes a VCR mechanism that relies on electric power to adjust a compression ratio of the VCR engine. The compression ratio is maintained by hydraulically-assisted engagement of a mechanical locking pin with an S-link of the VCR mechanism, holding a position of the VCR mechanism while an electric motor, used to adjust a position of the S-link, may be deactivated.
