Majority of internal combustion engine not able to convert all chemical energy into mechanical energy. Nearly 25% of heat energy used is transferred to exhaust system. Exhaust heat power recovery system can be used exhaust heat for generation of electricity which is used for charging the car battery. Exhaust heat power generation system helps to reduce load on the car alternator and enhancing fuel efficiency by saving fuel. Major OEMs such as BMW, Honda, Renault already focusing on exhaust heat recovery system by using thermoelectric generators. Latest stringent emission norms by regulatory bodies owing to environmental issues, growing demand for fuel efficiency of the vehicles likely to drive the market of exhaust heat power generation system during forecast period. To meet all stringent norms and fuel efficiency demand OEMs are developing exhaust heat power generation system. However, in developing countries norms regarding vehicle emission are not stringent as compare to...
