The present research work is focused on electricity generation from the heat energy which is wasted through the burnt exhaust gas (BEG) of an internal combustion (IC) engine.  A horizontal tube straight pass duct (HTSPD) type heat exchanger (HE) with a thermoelectric generator (TEG) was used for energy recovery. The HTSPD type HE was designed, fabricated and experimentally investigated the capacity for power generation in connection with TEG. In HTSPD type HE, water was used as the working fluid to transfer heat from the burnt exhaust gas to the TEG modules. A 6-kW diesel engine was used for the experimental analysis and the load on the engine was varied from 25% to 100% in steps of 25%. It was observed that a maximum of 0.27 kW of electricity was produced when the fluid temperature in the heat exchanger (HE) was maintained at 138°C, and the engine was operated at 100% load condition. The electricity produced by TEG modules enhances the overall efficiency, and this method also considerably reduced the thermal pollution due to high-temperature exhaust emissions.
