The present invention relates to an energy recovery system (51), which withdraws heat from a feed medium (52) containing heat energy, and—which has a heat transfer system (53) for this purpose, in order to transfer heat energy from the feed medium to a useful medium (54). According to the invention—the heat transfer system (53) has a separation system (57) which spaces apart the two media (52, 54); the heat transfer system (53) has at least one first exchanger zone (35), which allows the transfer of heat from the feed medium (52) to the useful medium (54) as long as the temperature of the feed medium is higher than that of the useful medium (54, 54′); and—the heat transfer system (53) has at least one second exchanger zone (56), which allows the transfer of heat from the feed medium (54, 54′), even when the temperature of the feed medium is lower than that of the useful medium.

The cooling pipe 3 is in tight attachment to the outer circumferential surface of the thermoelectric power generation module 2.

An exhaust component assembly for a vehicle exhaust system includes a housing defining an internal cavity configured to receive an exhaust gas after-treatment component. A first chamber is in fluid communication with the internal cavity upstream of the exhaust gas after-treatment component. A first nozzle introduces fluid into the first chamber and a first valve controls flow of the fluid from the first chamber into the internal cavity. A heat source is associated with the first nozzle or first chamber. A second chamber is in fluid communication with the internal cavity upstream of the exhaust gas after-treatment component, and the second chamber is a non-heated chamber. A second nozzle introduces fluid into the second chamber and a second valve controls flow of the fluid from the second chamber into the internal cavity. A controller controls the first and second valves based on at least one predetermined operating condition.

Disclosed is an efficient recycling system for exhaust energy of an internal combustion engine. Firstly, a thermoelectric generation device recycles high-temperature waste heat energy in the exhaust of the internal combustion engine and recycles high-temperature heat that originally radiates into the ambient atmosphere on the surface of the volute (24). Secondly, pressure energy in the exhaust of the internal combustion engine is efficiently recycled by using a turbocharging device, and the efficiency of the turbocharging device is improved through the graphite sealing device. Finally, low-temperature waste heat energy in the exhaust of the internal combustion engine is efficiently recycled by using an organic Rankine cycle device. The risk of decomposition caused by the fact that the working medium used by organic Rankine cycle works in a high-temperature environment is avoided, thereby ensuring the cycle efficiency and the working reliability of the organic Rankine cycle.
