CI engine waste energy conversion to electric power by using TEG.

All internal combustion engines have a high rate of energy loss while operating; the cooling and exhaust systems of the engine squander the vast majority of the energy generated during combustion. The use of this energy improves engine efficiency. One application of this power is to improve the efficiency of the engine's air pumping, which is done via a turbocharger. Use thermoelectric generators (TEGs) to convert heat energy into electrical energy. A thermoelectric generator type (12715) mounted outside the exhaust terminal was used in this study. A system consisting of four thermoelectric generators was set up and linked in series and parallel. The current, voltage, power, and temperature variations via the thermoelectric generator's two sides were measured using measurement instruments. At an ambient air temperature of 37°C, with the engine speed at 2400 rpm, a fuel consumption of 0.69 kg/hr, and a brake power of 1.93 kW, the practical phase of the study was completed. The empirical results show that the greatest voltage and power that can be produced by connecting four thermoelectric generators in series is 23.4 volts and 68.8 watts, respectively. Additionally, when the thermoelectric generator was connected in parallel, the highest current production was 10.8 imper.
