Abstract: This paper presents an original model-based approach to the system level development and calibration of diesel powertrains for passenger cars, implemented in a comprehensive software tool. The models for the different subsystems are coupled to execute optimisation loops, involving also the system calibration, and are characterised by flexibility of usage, limited tuning effort and reduced computational time. As an example of the general approach, the engine model is described and some results from its execution are shown and compared with the measurements. Finally, a practical example is given of the usage of the tool for system level optimisation through a specifically developed methodology.
