Abstract
An engine exhaust heat recovery system includes an engine exhaust heat conduit that interacts with a two-phase fluid that exists in liquid and gaseous states within a single closed loop. A first heat exchanger, which may be a boiler, interfaces with and receives heat from the engine exhaust conduit. Exhaust heat energy converts the fluid from the liquid state into the gaseous state for transfer into a heat expander situated downstream of the first heat exchanger. The heat expander utilizes the gaseous heat energy to rotate a flywheel, and a system of clutches is situated and adapted to permit the flywheel to transfer mechanical energy for subsequent, selective production of work upon demand. In one disclosed embodiment, the heat expander may be a high-speed turbine with a rotary power shaft coupled to a transmission and a plurality of clutches adapted to engage and actuate the flywheel.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
