Around 30-40% of the heat supplied in an internal combustion engine is rejected through the exhaust gases. So, the engine overall efficiency can be improved if this waste heat was converted to usable energy. Thermoelectric generators are solid states devices which can be used to convert thermal energy to electrical energy depending on the See beck effect principles. In the present work; Sahin 131 H1 016; which is an old car model, was tested for thermoelectric generators device. The temperature distribution along the exhaust pipe was measured at different car speeds (0; 40; 60 and 80 km/h) with two loads. Also, the temperature distributions were measured with and without exhaust pipe insulation. The exhaust gases were analyzed to point out the car engine performance. Exhaust pipe temperature distribution can be utilized to estimate the power gain by thermoelectric generators.
