Nikolaus Held presents selected special combustion processes and their injection strategies for modern passenger car diesel engines in this study. As a representative example, the author initially designs a control system for the combustion position and shape during particulate filter regeneration. This significantly enhances combustion stability, as demonstrated by experiments. Subsequently, Held investigates a model-based combustion control. Using a semi-empirical approach based on cylinder pressure, he models the temperature before the turbine and quantifies the influence of the accumulated post-injection on mean pressure and exhaust gas temperature. In addition to the rapid responsiveness of the control concept, the approach to characterizing post-combustion also provides added value compared to the current state of the art.
