摘要: Abstract Automotive fuel efficiency can be increased by thermoelectric power generation using exhaust waste heat. A high-temperature generator (TEG) that converts engine heat into electricity is simulated based on a light-duty passenger vehicle with 4-cylinder gasoline engine. Strategies to optimize TEG configuration and exchanger design for maximum improvement are provided. Through comparison of stainless steel silicon carbide exchangers, it found both the optimal increase highly dependent thermal conductivity material. Significantly higher obtained exchangers at taller fins longer along flow direction when compared exchangers. Accounting major parasitic losses, 2.5% achievable newly developed nanostructured bulk half-Heusler modules.
