Abstract
Methods and systems for damping an impact velocity in an engine system are provided. In one example, the engine system comprises a variable compression ratio (VCR) mechanism including a rod length adjustment assembly configured to adjust a distance between a crankshaft interface and a piston interface. The rod length adjustment assembly also includes a fluid control circuit including a damping cavity positioned between a first rod section and second rod section and configured to dampen a relative motion between the first and second rod sections during a compression ratio adjustment to reduce noise, vibration, and/or harshness (NVH).
