    Steel pistons for more efficient diesel engines

    With a new cooling concept, an automotive industry supplier is expanding the range of applications for steel pistons in diesel engines. The Stuttgart-based company is testing a liquid alloy comprising sodium and potassium, which dissipates heat from the particularly thermally loaded piston head. This innovative steel piston concept is designed to enable even further increases in the specific power of car diesel engines. In the case of long-running engines for industrial applications and commercial vehicles, the component and engine oil load is significantly reduced while the expected service life and oil change intervals are prolonged.  more...
     

    TU Darmstadt opens research factory

    Last week, the ETA model factory officially opened its doors. Here, scientists at the Technical University (TU) Darmstadt are researching under real conditions and at full scale how industry can use energy more efficiently by linking all building and production components. By considering the entire system – consisting of machines, energy storage systems, building technology and the building envelope – the intention is to reduce the primary energy requirement in production by 40 per cent.  more...

    Once coated, everything runs smoothly

    The wear and energy consumption of machinery increase dramatically if the machines are not optimally lubricated. In many cases, however, ideal lubrication is impossible, for example, in free-running motorcycle chains or agricultural machinery. To meet these operating conditions, researchers are therefore developing new coatings, and lubricants adapted to them, as part of the CHEOPS3 project. The twelve project partners from industry and science want to achieve long-term protection against wear, even with minimal lubrication and dry friction, so as to increase the efficiency of machines.  more...

    Hybrid building machinery

    Hybrid drives make construction machinery not only more economical and quieter – the power from the two engines also provides power reserves for special loads. The advantages of combining a combustion engine with an electric drive have been demonstrated by the DEUTZ engine manufacturing company from Cologne using an excavator. In order to realise the full savings potential, the engineers have also closely examined the auxiliary units as part of the Green Industrial Diesel (GRID) project.  more...
     

    Start signal for model factory

    Mechanical engineers, construction engineers, architects and industry experts have developed a new production facility: the so-called ETA factory. The foundation stone was laid for it on 12 August 2014. This initiates the start of construction of the model factory at the Technische Universität Darmstadt, in which in future machines, building technology and the building envelope can be energetically linked and perfected. It is scheduled to open in October 2015.  more...
     

    Research funding for the energy turnaround increasing

    Energy research contributes towards the development of the processes and technologies necessary for achieving the goals of the energy turnaround. The German government has been continuously increasing funding for energy research since 2006. In 2013 alone, it spent 100 million euros more on this than in the prior year. This reinforced above all the research areas of energy efficiency and renewable energy sources. It provided just under 300 million euros for each of these subjects.  more...

    Researching in the global network

    International research collaborations are becoming increasingly important. Germany is involved in a variety of ways in international energy research. An important pillar in this regard is its involvement in the International Energy Agency (IEA). Germany is a founding member of this organisation. An IEA field of activity particularly relevant to energy research is its energy technology network.  more...
     

    Durable diesel engine with electronic control

    The engine manufacturers Hatz developed a diesel engine in the performance class of up to 56 kW with a common-rail injection system. Combined with a more compact design, the Lower Bavarian engineering company significantly reduced consumption. They also reduced both nitrogen oxide emissions with exhaust gas recirculation, and soot particle emissions with an entirely new combustion system. The engine concept developed in the research project is the foundation for a new line of water-cooled diesel engines.  more...
     

    “Heat pumps are ready for the smart grid”

    Over the last few years, heat pumps have become more efficient. In a recent interview, Marek Miara, head of the heat pump unit at the Fraunhofer Institute for Solar Energy Systems ISE, talked about research results and future development potential. His team has completed three large-scale monitoring projects in old and new buildings.  more...
     

    Highly efficient pump technology becomes obligatory

    The age of unregulated, glandless circulation pumps is coming to an end. Several technically outdated series with electronic controls will also no longer be available next year. They do not meet the strict efficiency requirements of the new EU ordinance subject to the European Ecodesign Directive (ErP), which comes into force in 2013.  more...
