Abstract
Methods and systems are provided for a VCR engine. In one example, the VCR engine includes a VCR mechanism that mechanically locks the engine pistons at a high compression ratio or a low compression ratio, utilizing locking pins that engage with eccentrics. Movement of the locking pins may be actuated by a valve that controls hydraulic pressure in the VCR mechanism where varying the hydraulic pressure adjusts engagement/disengagement of the locking pins.
