PhD position with research focus on exhaust gas aftertreatment for large ammonia engines (m/f/d)

Ammonia is currently the subject of increased interest as potential renewable energy carrier and alternative fuel for large internal combustion engines. However, the use of ammonia as a fuel brings new challenges not only regarding the combustion concept but also for the exhaust gas aftertreatment. In order to meet the increasingly demanding requirements for minimum pollutant and greenhouse gas emissions (e.g., NH3, NOx, N2O), it is necessary to develop advanced exhaust gas aftertreatment systems (EAS). Of particular importance in this context is N2O, as it is a highly potent greenhouse gas. For this reason, it is necessary to obtain a detailed understanding of the N2O formation and reduction processes in the exhaust path.
For the research area “Integrated Systems”, we are therefore seeking a motivated and innovative PhD student to investigate, analyze and validate EAS concepts for spark ignited and pilot-diesel ignited ammonia engines based on experiments with a flexible EAS test system on the single-cylinder engine test bed and to identify key influencing parameters of N2O formation in ammonia combustion environments by developing and applying an appropriate simulation model.
