Study of a Gear-Based Variable Compression Ratio Engine 2004-01-2931

At the end of four years Research & Development programme, the bench test results for the MCE-5 VCR engine are presented.
Downsized supercharged Variable Compression Ratio engines allow for a 30% fuel consumption reduction while providing high power and torque and opening the way to numerous pollutants emissions reduction strategies.
In this context, piston to crankshaft transmission by means of gears gives new opportunities for future mass production of rigid and robust low friction engines that conform to VCR requirements while improving piston and rings operation.
Through development programmes, the MCE-5 gear-based compression ratio control device proved its robustness and reliability, as well as its ability to allow the design of compact and efficient VCR engines which are easy to integrate into all vehicles.
