Recent developments in converting the thermal energy of exhaust gasses of  automobiles into electric power directly, require an extensive simulation  and design of appropriate thermoelectric generation system. This work aims  to create a physical model of engine exhaust system using Simscape language  to simulate waste heat recovery from the exhaust gasses using (Na, K)  co-doped polycrystalline tin selenide (SnSe) thermoelectric material. This  particular material exhibits a high Seebeck coefficient and extremely low  lattice thermal conductivity in power generation because of phonons  scattering by the rattlers (Na, K atoms) and Nano-structuring. In the  MATLAB/Simulink environment, a transient simulation is done for the recovery  of waste heat from a 1.5 liters engine using these specific material-based  thermoelectric modules. According to the results obtained, at the  temperature gradient of 285 K across its sides, electrical power of 10.4  watts with a conversion efficiency of almost 5 percent is produced from one  module. The total system output power was 477 watts at the exhaust gas inlet  temperature of 900 K to the octagonal heat exchanger on which the modules  are mounted.
