Abstract:
A variable compression ratio engine comprises a stationary engine block in which movable members interact to enable a piston to translate in a combustion cylinder of the engine block, defining a stroke of the combustion piston The engine further comprises a self-contained device for adjusting the position of the top dead center of the combustion piston, the self-contained device being connected to or built into at least one of the movable members and having a high-pressure hydraulic chamber to counteract the combustion and inertial forces at the bottom dead center, a low-pressure hydraulic chamber to counteract the inertial forces at the top dead center, at least one calibrated conduit to enable hydraulic fluid to flow between the high- and low-pressure hydraulic chambers, and return means to bring the device back to a nominal position.

Claim (Index 20):
The variable compression ratio engine according to  claim 19 , wherein the average characteristics of the mechanical return device and the calibrated conduit enable adjustment of the top dead center of the combustion piston to average tension and compression forces in compliance with a predetermined equation.
