An internal combustion engine system that converts thermal energy from an exhaust of an engine to mechanical energy includes a heat exchanger thermally coupled to an exhaust from an internal combustion process. The heat exchanger receives a heat transfer fluid therein. A generator is coupled to the heat exchanger. The heat transfer fluid expands and evaporates in the generator in response to heat from the exhaust of the internal combustion process. The expansion of the heat transfer fluid vapor converts thermal energy of the heat transfer fluid to mechanical energy.
