DeNox Project starts


In September 2017, RWTH Aachen University together with further partners started a joint research project on new exhaust aftertreatment systems for ultra-clean engines with highest efficiency. The project “Efficient DeNox strategy for lean combustion engines” is sponsored by the Federal Ministry of Education and Research (BMBF).


The project consortium consists of the RWTH facilities Institute for Combustion Engines (VKA), Institute of Inorganic Chemistry (IAC), Institute of Technical and Macromolecular Chemistry (ITMC) and the Central Facility for Electron Microscopy, the Institute for Materials Synthesis and Processing (IEK-1) at the Institute of Energy and Climate Research of Forschungszentrum Jülich GmbH as well as the companies Clariant AG, FEV Europe GmbH, Ford-Werke GmbH, DEUTZ AG, Sasol Germany GmbH and Umicore AG & Co. KG.

Future emission limits are only achievable through conceptual and technical modifications in the exhaust gas aftertreatment. For this purpose the known catalyst technologies – the storage catalyst and the SCR catalyst – shall be combined with the help of new materials resulting in a novel catalyst technology. The project offers the possibility to represent catalysts in its entirety for the first time: from material research to the production of materials and catalysts as well as the simulation and development of operation functions to the integration of the catalysts into the vehicle. Besides passenger cars, commercial vehicles and machines with combustion engines are included. The project consortium moreover researches the optimization of the used materials based on models, the adaption of material production at suppliers, the improvement of coating for catalyst carriers, and the development of control-unit functions for the operation directly out of models. Moreover, the newly developed catalyst system will be tested on engine test benches before its implementation into the vehicle.
