[전기·전자] 열전변환 적용을 위한 가솔린차량의 전력 및 배열에너지 분석 연구

About 70% of energy input to internal combustion engine is rejected to atmosphere by heat. By utilizing this waste heat, a plenty of energy can be conserved in nationwide. One of possible ways is the thermoelectric generation to utilize engine's waste heat to provide auxiliary electric power. Under this concept. KIER has been developing the thermoelectric generation system to replace the alternator by converting the waste heat in the engine's exhaust directly to electricity, This system may reduce the shaft horse power of the engine. then improves the vehicle fuel economy and the exhaust emissions, This paper describes the preliminary study in which characteristics of the electric energy and exhaust heat energy in city and highway mode driving conditions are analysed. These results would be used to determine the optimum design parameters of the thermoelectric generation system.
