Abstract: An internal combustion engine includes a cylinder block defining first and second cylinders, and a cylinder head coupled to the block. The engine also includes a passage having a first outlet and a second outlet for exhausting post-combustion gasses from the cylinder head. The engine additionally includes a mechanism for selectively activating and deactivating the first cylinder and a turbocharging system having a low-flow turbocharger and a high-flow turbocharger. The low-flow turbocharger is driven by gasses from the first outlet and the high-flow turbocharger is driven by gasses from the second outlet. The turbocharging system also includes a first flow-control device that directs the gasses via the first and second outlets to the turbochargers when the first and second cylinders are activated. The first flow-control device also directs the gasses via the first outlet only to the low-flow turbocharger and blocks the second outlet when the first cylinder is deactivated.

Abstract: An internal combustion engine includes a cylinder block defining a cylinder, a cylinder head, an intake valve, an exhaust valve, and a variable exhaust valve timing mechanism. The engine also includes a turbocharging system configured to pressurize ambient airflow for delivery to the cylinder. The turbocharging system includes a low-flow turbocharger, a high-flow turbocharger, and a flow control device for selectively directing post-combustion gas to the low-flow and high-flow turbochargers. A controller directs the post-combustion gas to the low-flow turbocharger and selects a first predetermined exhaust valve timing when the engine operates below a predetermined speed and above a predetermined load. Alternatively, the controller directs the post-combustion gas to the high-flow turbocharger and selects a second predetermined exhaust valve timing at or above the predetermined engine speed. The first predetermined exhaust valve timing traps less post-combustion gas in the cylinder as compared to the second predetermined exhaust valve timing.
