Projectnumber EXC 2186
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.

Title

Cyclic variations in highly optimized spark-ignition engines: experiment and
simulation of a multiscale causal chain

Acronym FOR 2687
Funding Deutsche Forschungsgemeinschaft (DFG)
Projectnumber FOR 2687
Description

The main aim of this research group is the systematic analysis of cyclic variations as the basis for further optimization of modern si combustion methods. Currently, the operational range of highly optimized si engines is limited by abnormal combustion phenomena such as misfiring, incomplete combustion or engine knock, which are all significantly influenced by cyclic variations. Existing strategies to minimize these phenomena always reduce the thermal efficiency and thus increase CO2-emissions. To further optimize future si engines it is therefore necessary to expand the operational range with a detailed understanding of the chain of effects regarding cyclic variations and enabling stable and efficient operation close to the stability limit. Causes and effects of cyclic variations are currently neither completely understood nor predictable.

Using novel, experimental procedures in combination with innovative model developments and simulation procedures, a detailed understanding of the mechanisms of action is achieved through forward and backward analysis of the multiscale chain of effects and predictive simulation methods are developed.

Title

Optimization-Based Multiscale Control of Low-Temperature Combustion Engines

Homepage Research Unit 2401
Funding

Deutsche Forschungsgemeinschaft (DFG)

Projectnumber FOR 2401
Description

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.

Title Integrated Energy Supply Modules for Roadbound E-Mobility
Homepage mobilEM
Funding Deutsche Forschungsgemeinschaft (DFG)
Projectnumber GRK 1856
Description

This demanding topic is addressed by a new post graduate program "Integrated Energy Supply Modules for Roadbound E-Mobility" (mobilEM) at RWTH Aachen University and has started on October 1st, 2013. The program is funded by Deutsche Forschungsgemeinschaft (DFG) and explores the physical foundations of electro-chemical energy storage and its combination with novel fuel-operated range extender units. Fuel-operated range extenders allow a reasonable dimensioning of the electrical energy storage system size and its thermal conditioning. Additionally, an efficient air conditioning of the passenger compartment can be achieved.
