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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
