Abstract
According to the disclosed embodiments, a thermoelectric generator (TEG) insert is used for recovery of engine waste heat. The embodiments include an engine having an exhaust manifold outlet, and an exhaust pipe having an inlet and an outlet. The TEG insert, which is configured to convert heat from exhaust gas leaving the engine into electrical power, may be disposed between the exhaust manifold outlet of the engine and the inlet of the exhaust pipe. The location of the TEG insert may maximize the thermal conversion of heat to electricity. Further, the size of the TEG insert may be minimized through the use of a high-efficiency nano-material. As a result, overall fuel economy may be maximized, the size of ancillary components, e.g., alternator, coolant pump, oil pump, etc., may be reduced, and minimal engine design change may be required to accommodate the TEG insert described herein.
