Abstract
An engine control system for controlling engine operation in activated and deactivated modes in a displacement on demand (DOD) engine includes an impulse charging device that is disposed upstream of an intake port of a cylinder of the DOD engine and that is operable to regulate air flow into the cylinder. A first module initiates impulse charging to regulate air flow into the cylinder when a desired engine torque output nears a first threshold engine torque output during engine operation in the deactivated mode.
