Abstract:

 

In this study, a waste heat recovery system (WHRES) design with a heat exchanger inside to generate electricity from the exhaust gas heat energy discharged from a single-cylinder gasoline motorcycle engine using a thermoelectric generator (TEG) and system performance measurements were made. It was desired that the WHRES should not interfere with the flow of exhaust gas and be easily mounted on any engine. Measurements of the electricity generation performance of the system and the temperature distributions on the hot and cold surfaces of the TEGs were made. In addition, the simulations of the system with Ansysy Fluent software were made and the test results and measurements were compared. Images were taken with a thermal camera to verify the temperature values measured during the experiments. A total of 6 TEGs, 3 above and 3 below, are placed on the heat exchanger symmetrically. The results were recorded during the engine's maximum power cycle of 5500 1 / min. Under this condition, 2W electrical power was obtained from TEGs at 30 ohm load resistance. The obtained waste heat recovery power can be used both for operating the LED warning lamps in the vehicles and for charging some mobile devices from USB. The average 371 K temperature measured on the cold surface of the TEGs yielded similar results with the average 374 K temperature recorded by thermal cameras and obtained by simulation. There is a difference of about 20 K between the hottest region and the coldest region on the cold surfaces of TEGs. Due to this difference, the electricity generation performance of TEGs decreases. This temperature difference can be reduced with changes to the WHRES design.
