MCE-5 VCR engines help defeat global warming

12.07.2005


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.

About MCE-5

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.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
