The energy lost in all internal combustion engines throughout the operation process is high; the most significant part of the energy produced during the combustion process is wasted meantime the engine cooling and exhaust systems. The exploitation of this energy is gained in terms of raising the efficiency of engines. This power can be used to enhance the air pumping to the engine to boost the effectiveness of combustion through the use of a turbocharger or used to raise the temperature of the incoming air into the combustion chamber within certain limits to increase the temperature at which the heat is added. The thermal energy enables to turn into electrical energy by employ thermoelectric generators (TEG). In this research, the thermoelectric generator was used which installed on the outer wall of the exhaust terminal. The four thermoelectric generators were installed and connected in series and parallel. The temperature changes through the two sides of the thermoelectric generator; current, voltage and power were measured by using instrumentation tools. The practical part of the research was accomplished operation condition of an engine speed of (2200 rpm), the fuel consumption of (0.67kg/hr) brake power of 1.87kw and an ambient air temperature of 11°C. The experimental outcomes show that the maximum voltage generated from the four thermoelectric generators when connected in series is (17.01volt), and the maximum power generation. Also, the maximum current generation was 15.49 imper when connecting the thermoelectric generator in parallel
