Abstract As current internal combustion engine has the ability to convert 25% of heat into mechanical work under normal driving condition. Nearly 55 to 80% of the heat is carried away by the coolant and the exhaust. Where the electrical energy needed in the vehicle alternator is also consuming the particular amount of fuel indirectly. So, by using seeback effect the exhaust heat is converted into electricity which will reduce the load on the alternator where fuel consumption is reduced. But as the overall conversion efficiency of thermoelectric generator by using seeback effect is only 5%.It can be improved by optimizing the parameter such as temperature difference of hot exhaust and water inlet junctions, Load on the engine, Speed of the engine, Thermoelectric material. Since the material is fixed as J type material (chromel- constantan) due to its low cost it can’t be changed. Where by optimizing the best parameter for single module thermocouple. The total emf on series connection is increased considerable amount. Thus in this paper, the best operating parameters for single J type thermocouple are analyzed and the maximum emf generated in using seeback effect is identified and the total fuel consumption saved by seeback effect in diesel engine is calculated.
