MCE-5 Development    LYON   France
Jul 12, 2005 Designed to replace fixed compression engine blocks, Variable Compression Ratio Model MCE-5 integrates power transmission and compression ratio control. Main structure gives hydrodynamic bearings optimum geometrical environment. Roller-guided piston is not subjected to slap or radial stress, and engine block has no negative effects on other components or vehicle. Exhaust and transmission connections are identical to conventional engines.
