摘要： An internal combustion engine includes a crankshaft and first and second cam actuated intake valves. A method for operating the engine includes providing a first intake cam configured to actuate the first cam actuated intake valve, and providing a second intake cam configured to actuate the second cam actuated intake valve. The second intake cam is phase adjustable relative to the crankshaft independently of the phase of the first intake cam relative to the crankshaft. A controller is provided and configured to selectively retard the phase of the second intake cam to effect later closing of the second cam actuated intake valve sufficiently to reduce the effective compression ratio of the engine. Additionally, the first intake cam may be phase adjustable relative to the crankshaft independently of the phase of the second intake cam relative to the crankshaft and the controller may additionally be configured to selectively advance the phase of the first intake cam to effect earlier opening of the first cam actuated intake valve sufficiently to increase internal exhaust gas recirculation.

摘要： A variable valve actuation (VVA) system comprises a spark control module and a phaser control module. The spark control module maintains a spark timing of a cylinder at a maximum braking torque (MBT) spark timing during engine idling. The phaser control module, during the engine idling, adjusts an intake valve timing of the cylinder away from a predetermined intake valve timing. The predetermined intake valve timing corresponds to a maximum air per cylinder (APC) for the cylinder at a current engine speed. The adjustment of the intake valve timing produces an APC that is less than the maximum APC.
