While more than 65 percent of the fuel energy is lost as waste heat in the form of hot exhaust gases and cooling water, heat recovery promises one of the biggest fuel economy potential regarding the technologies available in the next 5 years.
Applied to trucks, buses or passenger cars, a bottoming Rankine Cycle (RC) on exhaust heat shows a great potential in fuel consumption reduction [
Founded in 2009, Exoès has been developing an axial piston expander accepting high temperature vapor of water or ethanol, whose hot side can run oil-free. We will explain the key points of this technology, our technical options and last simulation and tests results with a focus on gasoline passenger cars.
