Investigations on the Deposit Formation and Decomposition from Urea in SCR Systems

Abstract

The research project (FVV project no. 1262) was performed by the Institute of Chemical Technology and Polymer Chemistry (ITCP) of the Karlsruhe Institute of Technology (KIT) under the direction of Prof. Dr. Olaf Deutschmann and Prof. Dr. Jan-Dierck Grunwaldt and by the Institute of Powertrains and Automotive Technology (IFA) at the TU Wien (TUW) under the direction of Prof. Dr. Bernhard Geringer. Based on a decision taken by the German Bundestag, it was supported by the Federal Ministry of Economic Affairs and Energy (BMWi) and the AIF (German Federation of Industrial Research Associations e. V.) within the framework of the collective research networking (CORNET) program (IGF/CORNET no. 177 EN). The work of TU Wien was funded by the Federal Ministry of Transport, Innovation and Technology (BMVIT) through the Austria Research Promotion Agency (FFG). The project was conducted by the expert group "Deposits from AdBlue" led by Johannes Scholz (IAF). The authors gratefully acknowledge the support received from the funding organizations, from the FVV (Research Association for Combustion Engines e. V.) and from all those involved in the project.
