In this paper the newly developed Engine Dynamics Library is presented. Ever increasing consumer and regulatory demand for improved fuel economy and lower emissions forces the engines and Engine After-Treatment Systems (EATS) to be improved continuously. Since the complete system is very complex; models are useful in order to be able to cost efficiently develop new control strategies and select hardware. The library is based on a mean-value combustion model and the focus lies on modeling the gas exchange with real-time like simulation times; useful for engine optimization and for evaluation of control strategies. The library contains models of the standard engine components such as manifolds; pipe; turbines; compressors; valves; mechanics; etc. Simulation results from Dymola for a 13 L Volvo truck engine demonstrates that the models capture the engine dynamics and has sufficient accuracy to be useful in engine optimization. The model have been calibrated using surface fitting of maps and least-squares estimation of parameters in Matlab; as well as parameter optimization using JModelica and FMI.
