Abstract :

<p>&nbsp;<b style="text-align: justify; font-size: 12px;"><span style="font-size: 10pt; line-height: 115%; font-family: &quot;Times New Roman&quot;, serif;">This paper deals with the generation of electricity from heat of the exhaust gases using thermoelectric Generator (TEG). Thus produced electricity is stored in a battery for later consumption. A thermoelectric generator, also called a Seebeck generator, is a solid state device that converts heat flux directly into electrical energy (a form of thermoelectric effect). Thermoelectric generators function like heat engines, but are less bulky and have no moving parts. A cylindrical pipe is provided in between the exhaust manifold and the catalytic convertor .On this pipe, thermoelectric generators are mounted. When the exhaust gases flow through this pipe as the engine is turned on, the pipe gets heated. This heat is converted into electricity by these TEGs. The TEGs are mounted in such a way that their hot side is in contact with the pipe and a coolant is provided to the cold side. Due to the temperature difference provided the electrons and holes of the thermoelectric semiconductors will try to move towards the junction. The flow of these electrons produces a voltage in the circuit. Since all the TEGs are connected in series the EMF produced by each TEG sums up. The voltage thus produced is stored in external batteries and used for further purposes.</span></b>< /> <b><span style="font-size: 10pt; line-height: 115%; font-family: &quot;Times New Roman&quot;, serif;">< clear="all" style="page-eak-before:always;&#10;mso-eak-type:section-eak" /> </span></b></p>
