Simulation was employed to estimate the fuel economy enhancement from the application of an exhaust heat recovery system using a thermoelectric generator (TEG) in a series hybrid. The properties of the thermoelectric elements were obtained by self-assessment and set as the conditions for estimating the fuel economy. It was concluded that applying exhaust system insulation and forming the appropriate combination of elements with differing temperature properties inside the TEG could yield an enhancement of about 3% in fuel economy. An actual vehicle was also used to verify the calculation elements in the fuel economy simulation, and their reliability was confirmed.
Exhaust heat recovery ofautomobile using thermoelectric generators (TEGs) has strong potential fbr improving fuel economy.In this studM simulation was performed to estimate the fuel economy improvement using an exhaust heat recovery system with thermoelectric generators in a series hybrid. The study investigates on fuel economy benefit from electrical power generation along with quick warm-up of engine due to heat transfer from exhaust gas to coolant accompanied with pewer generation and estimates benefit of TEGs against future fuel economy regulatiens.It is concluded that electrical output generated by TEG using exhaust heat and quick warm-up of engine coolant could yield an improvement of about 3% in fuel economy in US 5 cycles fuel economM and additional benefit toward futureCorperate Average Fuel Economy (CAFE) and Greenhouse gas (GHG) regulations could be expected. engine control and makes fuel economy worse compared to hot start. It is known that an exhaust heat recovery system which transfers heat from exhaust gas to engine coolant is effective to improve fuel efficiency after a cold Copyright @ 2012 by the Japan Society of Mechanical Engineers -50-NII-Electionic
