System Optimization of Turbo-Compound Engine (First Report: Compressor and Turbine Pressure Ratio) 2009-01-1940

A turbo-compound engine system is considered to be an effective way to improve the thermal efficiency of diesel engine. In this study, the sensitivity of the design parameters of turbo-compound system, such as the compressor pressure ratio and the turbine expansion ratio, has been analyzed using a numerical analysis. And the potential of the improving effects of the thermal efficiency by turbo-compound system has been also examined. As the results, it was found that there are the optimum values of compressor pressure ratio and turbine expansion ratio to maximize the thermal efficiency of turbo-compound engine.
