METHOD AND DEVICE FOR HEAT RECOVERY AND ITS TRANSFORMATION INTO MECHANICAL POWER IN DRIVE SYSTEM OF VEHICLE Russian patent published in 2017 - IPC F02G5/02 F01K3/08 

FIELD: transportation.

SUBSTANCE: extending in a circulation loop operating means is evaporated by at least one integrated in the circulation loop operating means evaporator, using waste heat from the internal combustion engine of a vehicle, wherein the generated steam is supplied in connected with the internal combustion engine expander, and then the exhaust steam from the expander is transferred back to at least one condenser to the liquid phase again. The circulation loop operating means downstream of the at least one evaporator, integrated with at least one controllable and/or adjustable by a control and/or regulating device valve, and a steam battery, so that, in particular, when not required drive power expander, and/or running without combustion of the internal combustion engine, formed by pairs, preferably simultaneously closed expander, at least partially fed to a steam accumulator, and the accumulated steam to the accumulator steam, preferably immediately after a phase of accumulation of steam at the required drive power of the expander and/or during operation with an internal combustion engine fuel, where combustion is at least partially fed back again into the circulation.

EFFECT: invention improves the efficiency of the drive system.
