Abstract

For an internal combustion engine having two cylinder banks forming a V-shaped cylinder block, a turbocharger system including a high pressure turbocharger disposed in a valley between the cylinder banks, a first low-pressure turbocharger disposed adjacent an outer side of one of the cylinder banks, and a second low-pressure turbocharger disposed adjacent an outer side of the second cylinder bank. Intake and exhaust ducts connect the components of the engine and turbocharger system to and electronically controlled valves associated with the ducts permit the system to operate either in a split series mode or a low-pressure-only mode.
