Abstract

A powertrain system is provided and may include a combustion engine, a crankshaft, and a turbo-compounding system. The combustion engine may include an intake manifold and an exhaust manifold. The crankshaft may be driven by the engine. The turbo-compounding system may be configured to drive the crankshaft and may include a first turbine and a drive system. The first turbine may include an inlet fluidly communicating with the exhaust manifold. The drive system may include an input shaft driven by the first turbine, and an output shaft engaged with the crankshaft. The drive system may be configured to drive the output shaft at more than one drive ratio relative to the input shaft.
