    Car engines are becoming increasingly compact with a greater specific power. This reduces the weight, moving masses and fuel consumption. In the engine, however, the temperatures and pressures rise for individual components. This causes conventional pistons made of aluminium to reach their limits. The new BINE Projektinfo brochure entitled "Steel pistons for more efficient diesel engines" (14/2016) presents a cooling concept for engine pistons using a liquid metal alloy. Compared with aluminium, steel offers greater strength against thermal and mechanical loads.

  • The energy-saving data glasses

    Data glasses mirror information to the eye without interfering with the wearer‘s vision. However, the battery runs down quickly, because the electronics consume a great amount of electricity while playing back the images. Fraunhofer researchers have developed an energy-saving display that reduces the power consumption to a fraction. The new display will be presented at the electronica trade fair in Munich from November 08-11, 2016.
