Abstract
Various embodiments of methods and systems for varying the compression ratio in opposed-piston engines are disclosed herein. In one embodiment, an opposed-piston engine can include a first phaser operably coupled to a first crankshaft and a second phaser operably coupled to a corresponding second crankshaft. The phase angle between the crankshafts can be changed to reduce or increase the compression ratio in the corresponding combustion chamber to optimize or at least improve engine performance under a given set of operating conditions.
