This paper presents the development of a high performance Low Pressure Turbine for turbocompounding applicationsindownsized gasoline engines. The LPT was designed to fill the existing technology gap where no commercially available turbines can operate effectively at low pressure ratios (1.05 - 1.3), in order to drive a small electric generator with continuouspower output of 1.0 kW. The newly designed LPT was tested in a gas test stand and its impact on Brake Specific Fuel Consumption was assessed with on engine testing carried out on a 1.0L EcoBoostgasoline engine.
