Patent ID: 8407998

Claim:
A heat recovery system for an engine including an exhaust and an exhaust gas recovery system, the heat recovery system including: a first loop including fluid, a conduit, a first heat exchanger, a second heat exchanger and a valve wherein the fluid flows through the conduit, the first heat exchanger conducts heat energy between the fluid and the exhaust gas recovery system and the second heat exchanger conducts heat energy between the fluid and the exhaust and the valve is configured to control the amount of fluid passing through the second heat exchanger; a second loop including a third heat exchanger, a fluid, a conduit and a heat conversion device, wherein the fluid flows through the conduit, the third heat exchanger transfers heat from the exhaust gas recovery system to the fluid, and the heat conversion device converts heat from the fluid; and a fourth heat exchanger transfers heat from the first loop to the second loop.
