Also in modern combustion engines, the maximal energetic efficiency is lower than 45%, which means that 55% of the supplied energy is lost and released to the environment. Automobile manufacturers and R&D partner suppliers are taking a special concern in investigating heat energy from exhaust gases, with the aim of recovering part of the heat by means of a Rankine Process and using it for energy cogeneration in the automobile. In the context of this Master Thesis, a new calculation software of the different thermodynamic states of the waste heat recovery system has to be programmed and used together with the rest of the available calculation tools. Another objective of this Master Thesis is the set up of valid simulation models for the different components of the heat recovery system based on measured testing data. This technical conditions and on the other hand the cycle requirements with the final objective of finding optimized states for each component. Finally, in order to reflect the behaviour of the system as a whole, the integration of the different simulated components of the waste heat recovery model would come in very useful. A complete simulation of the system would enable the estimation of optimization issues of the different parameters and operating points of the cycle.
