From 22 to 25 July, the Chair of Vehicle Propulsion Systems was in Japan to work on the joint research project "Postoxidation" with Chiba University and Meji University.
The innovative goal of this research project is the development of a post-oxidation model for 0D/1D engine simulation. In order to develop such a model, a deeper understanding of the decisive mixing and oxidation process of purge air and fatty combustion products is required. Therefore, a mix-optimized exhaust manifold geometry will be developed and evaluated on the engine test bench. The resulting post-oxidation model will be used, among other things, to investigate critical acceleration manoeuvres in the RDE. In this way, limits to the applicability of post-oxidation can be identified, e.g. with regard to exceeding the maximum catalyst temperature. While the measurements are carried out by Chiba and Meiji Universitys in Japan, we at IFS take care of CFD simulations and 0D/1D model development. Last week we met our Japanese colleagues in Tokyo to exchange preliminary results and to communicate them to the participants of the project committee.
The project is supported by the following research associations:
- AICE (Research Association of Automotive Internal Combustion Engines | Research Association for Vehicle Engines)
- NEDO (Japanese New Energy and Industrial Technology Development Organisation)
- AiF (Association of Industrial Research Associations)
- FVV (Research Association for Internal Combustion Engines)
The project started in October 2018 and will continue until September 2020.
