Cyclic variations in highly optimized hydrogen engines: Experiment and simulation of a multiscale chain of cause and effect
|Funding||Deutsche Forschungsgemeinschaft (DFG)|
In addition to electrified drive systems, hydrogen-fueled internal combustion engines can represent a possible carbon-neutral solution in the transportation sector if the hydrogen is produced by electrolysis from renewable energy sources. The overarching goal of the research group is the systematic analysis of cyclic variations as a prerequisite for the further development and optimization of hydrogen combustion engines.
The physico-chemical properties of hydrogen require the further development of existing methods that were developed in the first funding period. These include combustion modelling, optical as well as thermodynamic experimental investigations and a forward and backward analysis of the multiscale chain of cause and effect.

|Description||The increasing availability of non-fossil energy technologies opens unprecedented possibilities to re-design the interface of energy and material value chains towards a sustainable future. The fundamental research in the Cluster of Excellence “The Fuel Science Center – Adaptive Conversion Systems for Renewable Energy and Carbon Sources” (FSC) aims to integrate renewable electricity with the joint utilization of bio-based carbon feedstocks and CO2 to provide high-density liquid energy carriers (bio-hybrid fuels), which enable innovative engine concepts for highly efficient and clean combustion. FSC will generate fundamental knowledge as well as novel scientific methodologies to replace today’s fossil fuel-based static scenario by adaptive production and propulsion systems that are based on renewable energy and carbon resources under dynamic system boundaries.|

Optimization-Based Multiscale Control of Low-Temperature Combustion Engines
|Homepage||Research Unit 2401|
Deutsche Forschungsgemeinschaft (DFG)
The ecological and economic energy supply poses a central challenge for society. For realization of high efficiency with simultaneously low pollutant emissions, the FOR2401 investigates the promising low temperature combustion. For successful realization of the multiscale control concepts, fundamental research questions from the disciplines of chemistry, combustion science, engine technology, numerical methods, and control technology have to be addressed.
Based on this knowledge, tailored control methods shall be developed which rely on real-time optimization and allow for control on time scales that are smaller than the ones achievable with state-of-the-art concepts. The research is conducted in close collaboration between scientist of pure and applied science disciplines from the University of Bielefeld, University of Freiburg and RWTH Aachen University.
