Modeling Post-Injections for HiL-Simulations

In this paper a model of the diesel combustion is introduced, which can simulate post-injections for the regeneration of diesel particulate filters. The combustion process is modeled with two phases. The intended use is a HiL-simulator for engine control units. The model must therefore be executed in realtime.

For comparison a model based on the work of Constien (Constien, 1991) is also described. This model is currrently used for HiL-applications.

Evaluation plots of the accuracy of the models are included as well as plots of the execution time on HiL-hardware.
