Design of the Modelica Library VehProLib with Non-ideal Gas Models in Engines

This thesis covers the reconstruction and the redesign of the modeling library VehProLib, which is constructed in the modeling language Modelica with help of the modeling tool Wolfram SystemModeler. The design choices are discussed and implemented. This thesis also includes the implementation of a turbocharger package and an initial study of the justification of the ideal gas law in vehicle modeling. The study is made with help of Van der Waals equation of states as a reference of non-ideal gas model. It will be shown that for the mean-valueengine- model, the usage of ideal gas law is justified.
