DESIGN AND FABRICATION OF EXHAUST GAS ASSISTED AIR COOLING SYSTEM

The main objective of this paper is to recover the waste heat from the automotive engine exhaust into useful electrical energy by using thermo electric power generator. Converting the waste heat energy of the exhaust gases into electric power would bring some measureable advantage. Modern automobiles equipped with combustion engines tend to have large number of electronically controlled component. Contemporary car engines exhaust up to 30-40% of heat generated in the process of combustion into useful mechanical work and losing the remaining power in the form of heat to environment. Thermoelectric device could convert some of this waste heat into useful electricity. Therefore, even partial use of the waste heat would allow us to recharge the battery significantly. Since voltage generated is lower than our requirement, we placed a booster circuit to increase the output voltage and to store in the vehicle battery.
