MCE-5 VCR engines help defeat global warming
MCE-5 of France has launched the MCE-5 VCR engine block - a mechanical solution that allows the mass production of VCR (Variable Compression Ratio) engines to the required environmental standards. The MCE-5 VCR engine block is designed to replace traditional fixed-compression engine blocks. The MCE-5 technology is an all-in-one VCR engine block that combines power transmission and compression-ratio control.
VCR is a major technical innovation that makes it possible to tackle the main environmental and energy issues affecting the automotive industry. VCR will permit the production of attractive, powerful and fuel-efficient vehicles that meet European Union and global objectives of reducing greenhouse gases and pollutant emissions. VCR strategy induces a fuel-consumption reduction of about 30% while remaining compatible with the simplest and most efficient after-treatment device - the three-way catalyst.
The MCE-5 integrates long-life gears and an exclusive roller-guided piston that is not subject to slap or radial stress. This feature ensures exceptional durability and reliability for high-loaded VCR engines on high mileages. This means that the MCE-5 meets one of the greatest challenges for downsized engines with extreme power and torque density - durability.
The great strength of the MCE-5 VCR engine block also results from the rigidity of its crankshaft and of its main structure, which give the hydrodynamic bearings an optimum geometrical environment and a long lifespan. The MCE-5 VCR engine block has no negative effects on the other components or the vehicle. Exhaust and transmission connections are precisely the same as those of a conventional engine.
Designed in 1997, the MCE-5 VCR engine block has been tested and improved in successive stages. The new MCE-5 generation is suitable for marketing and its components are manufactured using mass production techniques. Its production cost is in line with the profitability criteria sought in the car manufacturing industry.
Mastery of production costs and exclusive features means that the MCE-5 will help produce powerful, attractive and fuel-efficient vehicles that are more competitive and profitable for the automotive industry than diesel or hybrid vehicles. The MCE-5 VCR technology will also open the way to a set of decisive strategies that will enable the car industry to tackle future issues.
Based in Lyons, in south-east France, the MCE-5 Development Company was established in 2000 by a small group of engineers to carry out the MCE-5 R&D programmes. The MCE-5 Development Company is supported by major French institutions for energy saving, innovation and transportation - PREDIT programme (French programme for energy and transportation), ADEME (French Agency for Environment and Energy Management), ANVAR (French Agency for Innovation), French Ministry of Research and French Ministry of Industry.
A DVD is available from the company on request. It presents - in English or in French - all the MCE-5 technology in images. A short version lasts for four minutes and the one-hour version includes interviews.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
