Simulation was employed to estimate the fuel economy enhancement from the application of an exhaust heat recovery system using a thermoelectric generator (TEG) in a series hybrid. The properties of the thermoelectric elements were obtained by selfassessment and set as the conditions for estimating the fuel economy. As a result of the investigations is shown that the reduction in fuel consumption with a TEG installed in a series hybrid about 3% fuel economy enhancement could be expected. By using high-temperature type elements on the upstream side of the TEG, where exhaust gas temperatures are high and low-temperature type elements on the downstream side, where the temperatures are lower, the recovery efficiency was increased by about 30% compared to when high-temperature elements are used alone. The appropriate combination of elements upstream and downstream in the TEG was effective in fuel economy enhancement. The application of insulation in the exhaust system yielded a fuel economy enhancement, particularly in the high-temperature type elements where heat input can be effectively increased. A verification of the accuracy of the calculation elements in the fuel economy simulation was also conducted and the credibility of those elements was confirmed.
