The global increase in energy demand has driven the automotive sector to
rely heavily on fossil fuels, contributing to harmful greenhouse gas
emissions. Recent advancements in exhaust gas recovery aim to enhance the
efficiency of internal combustion engines, thereby reducing fossil fuel
consumption and mitigating global warming. This study explores the
potential of thermoelectric heat recovery systems in automotive applications,
focusing on recovering heat from exhaust gases to generate electrical
energy. A prototype exhaust system using 27 thermoelectric generators was
developed, demonstrating its potential to improve fuel economy by
converting waste heat into usable electricity. The study achieved a maximum
current of 0.47 A, a voltage of 13.05 V, and 6 W of electrical power over a
five-hour operation period. However, the system required a cooling load of
1.792 kW to maintain functionality, highlighting challenges in efficiency and
integration.
