International Journal of Engineering and Technical Research (IJETR) ISSN: 2321-0869, Volume-2, Issue-12, December 2014 81 www.erpublication.org Abstract — Fuel Economy and environment pollution of I.C. engine is severe problem worldwide, as fuel prices touching high value, increasing in number of vehicle. Use to make more pollution so to vanish this effect and to have economical engine in terms of fuel saving management. From 100% of Heat supplied to fuel only 40-45% of Heat is converted into mechanical work and other is frictional power so to use exhaust gases as a source of heat supplied again to engine can reduces pollution the desired system known as Exhaust Gas Recirculation System and other way to incorporate power from exhaust gas is thermo electric generation as exhaust gas of I.C. engine have ample amount of energy so to utilise it system is necessary called as thermo electric generator so as to impart stream of exhaust gas on surface of it and to generate small electric D.C .type of current depending upon temperature difference across intercooler or heat exchanger is installed in path of Exhaust Gas Recirculation running on Seebeck effect. So this is nothing but duel effect of waste heat can be used to reduce pollution as well can be able to generate small electric current D.C. type so can be able to charge battery ,tail lamp, head lamp. Parking light, door light, Indicator Lamp, G.P.S. system, Night Vision Camera etc.so as to reduce Frictional Power against alternator can save fuel.

INTRODUCTION In recent years the scientific and public awareness about increasing prices of fuel and pollution issues has bought in major interest to the research and technology field especially highly efficient internal combustion. In cylinder no. of cycles i.e. irreversibility‟s cycles playing its important role of caring work output by engine by heat supplied. All those processes carried out in cylinder and due to these transfer from the fluid to the cylinder wall and piston assembly and to the piston crown. According to four stroke cycle exhaust stroke contain the un burnt particles, exhaust gas after completion of power stroke except from exhaust manifold and exhaust valve & last to the exhaust pipe in these waste heat large amount of energy bounded with exhaust stream so can be used to generate electricity In these particular study engine used for research work is single cylinder four stroke water cooled C.I. Engine under which current study shows the overall use of waste exhaust gas in to usable form i.e. 1] Used to reduce pollution mainly NO by EGR system 2] Thermo electric generation.

So, significantly due to higher efficiency and lower fuel consumption by improving fuel economy indirectly and also reduce harmful gases such as oxides of nitrogen NO. Zhang X,Chau,KT states that the waste heat generated from petrol engine is as high as 30-35% also from 100%,25% of heat is utilized to produced the vehicle and technical description is well discussed in paper[15].Author Miller EW [9] investigated the percentages of fuel energy that would be converted into useful work i.e. 11% and also found the heat energy containing exhaust stream is of 27% is of no use. The second law i.e. exergy about fuel analysis shows the fuel energy is converted in to brake power and got a value by experimentation as 9.7% and exhaust about 8.4% respectively. The value of exhaust gas mentioned as a 18.7%of total fuel consumption and can be saved up to 33.9% by installing intercooler or heat Exchanger.[2,3].
