POWER PRODUCTION BY THERMOELECTRIC CELLS USING ENGINE EXHAUST GAS

摘要

The internal combustion engine used in majority of cars at the present time do not use their fuel input very efficiently.A majority of this energy is dissipated as heat in the exhaust.The related problems of global warming and dwindling fossil fuel supplies has led to improving the efficiency of the internal combustion engine being a priority.One method to improve the efficiency is to develop methods to utilize heat in car exhausts that is usually wasted.Two promising technologies that were found to be useful for this purpose were thermoelectric cells and heat pipes.Therefore this project involved making a bench type, proof of concept model of power production by thermoelectric cells using heat pipes and hot engine exhaust gases.8 cells were used and managed to produce 6.03W when charging the battery.
