Abstract
A waste heat recovery system for an internal combustion engine. The internal combustion engine includes first and second raised temperature portions. The raised temperature is higher at the first portion than at the second portion. A first evaporating portion generates a first vapor from the first raised temperature portion. A second evaporating portion generates a second vapor from the second raised temperature portion and with a lower pressure than the first vapor. First and second energy converting portions of a displacement type expander converts expansion energy of the first and second vapor into mechanical energy. A condenser and a supply pump are also provided.
