Abstract

Language:

An internal combustion engine (IC engine) represents a vital source of energy in transportation; however, a significant portion of the heat produced is wasted, necessitating effective recovery methods. This study investigates the potential of utilizing waste heat from an IC engine through a thermoelectric generator (TEG) to optimize power generation. The research focuses on the electrical characterization of TEG under varying configurations, particularly comparing series and parallel connections, to enhance the overall efficiency of energy recovery. Individual tests conducted on two TEG units were aimed at determining the influence of the heat source temperature on electrical output, voltage, and current performance. The results reveal that a series configuration yields a higher voltage output, whereas the parallel setup exhibits greater reliability. Ultimately, the series connection of TEG demonstrated the highest maximum output power derived from the waste heat of the IC engine. The study concludes by emphasizing the need for further research on improving heat exchanger designs to augment airflow and temperature differentials, thereby enhancing the efficiency of TEG power generation systems.
