Novel concept of exhaust gas tract improves turbocharging in combustion engines

The basic idea of the MEDUSA control concept is to divide the turbine inlet into several sectors. Turbochargers significantly increase engine performance and efficiency. Combustion engines currently possess various control elements that operate using different modes and restrictions. At the University of Stuttgart, a concept was developed to better control turbochargers. The innovative MEDUSA concept … Weiterlesen »

Enhanced ball screw drive with increased lifetime through novel double nut design

An invention of the University of Stuttgart combines a high precision with a minimum of preload. Ball screw drives with preloaded nuts are frequently used in machine tools. They are typically exposed to rather high load forces and must be in addition preloaded for high precision requirements. An excessive amount of preload, however, will cause … Weiterlesen »
