| description | Turbo compounding is one of the ways to recover wasted energy in the exhaust. This paper presents the effectiveness of series and parallel turbo compounding on a turbocharged diesel engine. A power turbine is coupled to the exhaust manifold, either in series or in parallel with the turbocharger, to recover waste heat energy. The effectiveness and working range of both configurations are presented in this paper. The engine in the current study is a 6 cylinder, 13 L diesel engine. Both the configurations were modeled with one dimensional simulation software. The current study found that series and parallel turbo compounding could improve average brake specific fuel consumption (BSFC) by 1.9% and 2.5%, respectively. When the power turbine is mechanically connected to the engine, it could increase the average engine power by 1.2% for the series configuration and 2.5% for the parallel configuration. |
