Methods and systems are provided for a variable compression ratio engine. In one example, an engine system may comprise: varying a compression ratio of a cylinder by selectively releasing combustion charge from the cylinder through a bleed valve on a cylinder head; and transforming the released combustion charge into usable electrical power at a turbine generator coupled downstream of the bleed valve. In this way, the compression ratio may be varied based on engine operating conditions to promote better engine performance and efficiency while producing electrical power from the charge gas bled from one or more cylinders in the engine.
