Gear Design and Dimensioning Study for a Variable Compression Ratio Engine 2005-01-3131

The MCE-5 VCR engine includes a gear mechanism, which transmits the piston motion to the crankshaft via the connecting rod.
This arrangement reaches main VCR engines requirements in respect of conventional engines characteristics such as piston kinematics, combustion chamber shape, or vehicle integration.
In addition, the MCE-5 design includes a roller-guided piston, which allows for a significant friction losses reduction while ensuring a great compatibility with high supercharging pressures on high mileage.
To ensure a safe operation and to meet all operational requirements, different studies have been carried out to design appropriate safe high loaded gears.
Several hundred hours of tests have been carried out on test bench under various operating conditions to validate the gear fatigue resistance and lubrication of the gear MCE-5 device. Positive results lead to various gear improvements and mass production perspectives.
