Through Flow Models for Engine Turbocharging and Ezhaust Heat Recovery

摘要：

Transportation represents over 30% of energy consumption and 20% to 25% of the carbon dioxide (CO2) release in the atmosphere, and the shares of which tend to increase. Energy consumption and CO2 emission of engines are two indissociable factors. Advanced integrated energy system (IES) technology, which combines engine turbocharging system with turbo exhaust heat recovery system by through flow design and integrated cycle optimization, appears to be a promising way to improve engine efficiency and reduce CO2 emissions. Compressor and turbine through flow models of a turbocharger or a turbogenerator for IEs technology has been developed and validated. On the basis of through flow models, turbochargers/ turbogenerators, intake and exhaust systems, and engine systems integration can be coordinately designed and optimized.
