Generation of Electricity from the Waste Heat of an IC Engine Using Thermo Electric Device

Abstract:

Electricity is very vital in our day to day life. The motive of our journal is to generate electricity from the from the exhaust gases of an internal combustion engine by the principle of Seebeck effect.Exhaust gases from an automobile bring out the excess heat generated which would be very high.The idea is to convert this exhaust heat to another form of energy i.e., electricity with the help of thermoelectric devices like thermocouples, thermopiles, Peltier device. The voltage generated by the thermocouple is very small and many thermocouples are required to make a practical thermoelectric generator. If a loop is made from wires using two dissimilar metals, a voltage will appear between the junctions of the wires if one junction is hotter than the other. Such a loop made with dissimilar metals is known as a thermocouple and the phenomenon is named the Seebeck effect. A semi conductor thermocouple device named Peltier device is used to convert the exhaust heat generated from an automobile into electricity.
