Abstract : Heat energy exhausted from an automobile, is expelled into atmosphere without being utilized. This energy can be utilized for constructive purposes if it is directed properly. Thermoacoustic engine uses the principal of Stirling Cycle which develops a reciprocating motion of the piston with the help of Thermal energy. This reciprocation plays an important role in the extraction of Heat Energy and converting them into Electric Energy. The proposed system will be referred as Thermoacoustic Convertor. It aims to be a technical permute in the field of automobile engine design as a Thermoacoustic Convertor intends to replace the Alternator, both physically and operationally. Basically, the principal used in this theory involves the interactions between temperature, fluid density and pressure gradient of the acoustic wave. The components used are stacks, resonating tube, cold heat exchanger, connecting rod, piston, dynamo, flywheel, ceramic chamber. Apart from the basic electricity generation, this paper also depicts a study of Thermoacoustic Exhaust Cleanser(TEC). The stacks are placed in a special arrangement which is designed precisely to reduce NOx, CO and HC which are eliminated as the product of combustion in an automobile. This piston-driven Thermoacoustic engine achieves an efficiency of 0.22 to 0.35 which is comparable to the common IC Engines. An alternator utilizes energy from the crankshaft. Thus, by the installation of a Thermoacoustic Convertor, some amount of energy can be saved. Keywords - Thermoacoustic Convertor, Technical Permute, Thermoacoustic Exhaust Cleanser
