Abstract

Methods and systems are provided for a piston. In one example, system may comprise a piston comprising a chamber in which a piston bowl may actuated independent of an oscillation of the piston. The chamber may receive a hydraulic fluid in order to adjust a position of the piston bowl within the chamber, thereby adjusting a compression ratio of a combustion chamber in which the piston may oscillate.
