Abstract
A waste heat recovery apparatus for use with an internal combustion engine includes a working fluid circuit having a first heating line and a second heating line parallel to the first heating line, a first heat exchanger in the first heating line operatively connected to transfer heat energy to the working fluid from a waste exhaust flow of an internal combustion engine, a second heat exchanger in the second heating line operatively connected to transfer heat energy to the working fluid from recirculating exhaust gas the internal combustion engine, and a recuperative heat exchanger operatively connected to transfer heat energy to the working fluid in the first heating line from the working fluid at a junction of an expander outlet and condenser inlet.
