Application of a Modular Simulation Approach: Optimizations from Combustion to Vehicle Management 2015-24-2505
The world of diesel is becoming more technically complex due to the increasingly restrictive legislation regarding emissions, fuel consumption, and real driving emissions evaluations (RDE). Simulation provides a mechanism for the investigation and optimization of diesel engine performance, new engine concepts, RDE, and after-treatment design. This can contribute to solve the problems that the restrictive legislation creates.
In addition to these generally valid capabilities of simulations, our model development is focused on the mission to use correctly sized models to reduce the usage of resources and make simulation an even more rapid and cost effective method.
In this contribution, we present our approach for simulation as an advanced integrated tool capable of answering challenging questions presented by emission and fuel consumption reduction in future legislation frameworks. Furthermore, the application of this approach is shown for different simulations of NOx storage catalysts that can be used either for exhaust gas treatment (EGT), calibration strategy optimization (lean model), or for EGT system layout definition (detailed chemical model).
