ABSTRACT: Internal combustion engine (ICE) efficiency improvement represents the most important challenge facing IC engine’s manufacturer. Through the recent decades, a significant improvement has been accomplished regarding IC engine efficiency improvement. However, all these improvements couldn’t increase the efficiency more than 45% or less. This means that about half of the fuel energy is lost as a heat discarding to the environment. This project aims to find an approach to use this lost heat energy and get a mechanical energy out of it. This lost heat represents a very good chance to use as a heat source for a steam generation. Then, this steam could use to run a steam engine. This approach could improve the total system (i.e. IC and steam engine) efficiency by about 8%. Moreover. This increasing in the efficiency may decrease the fuel consumption about 15%.
