摘要： Systems and methods for controlling an internal combustion engine include determining presence of charge dilution and selecting a spark restrike mode to provide multiple spark events during a single combustion cycle. Charge dilution may be determined based on commanded air/fuel ratio and exhaust gas recirculation, for example. Multiple spark events may be controlled using time-based restrike or current-based restrike in response to one or more operating parameters or conditions.

摘要： A system and method for controlling a variable displacement internal combustion engine having dedicated actuators associated with a group or bank of cylinders pre-positions actuators associated with the deactivated cylinders based on operating conditions associated with the activated cylinders to reduce torque excursions during reactivation. In one embodiment, a variable cam timing mechanism associated with the deactivated bank of cylinders is pre-positioned to achieve the stead state air charge based on engine speed and manifold pressure of the activated cylinders.

摘要： Systems and methods for controlling an internal combustion engine include adjusting fuel delivered to a cylinder during a transient event by an amount indexed by number of combustion events after detecting the transient event. A base fueling parameter may be adjusted by an adaptive correction value indexed by combustion events after the transient event is detected, with the adaptive value determined using air/fuel ratio difference of previous combustion events during similar transient operating conditions associated with the same combustion event index number. Ionization sensor signal characteristics may be used to determine actual air/fuel ratios used to determine the air/fuel ratio difference and corresponding adaptive correction values. The adaptive values may be modified in response to a vehicle refueling event based on an amount of added fuel relative to existing fuel in the vehicle fuel tank.

摘要： A system and method for detecting an operating mode of an engine or engine component modulate a first engine parameter and analyze a change in a second engine parameter in response to modulating the first engine parameter to detect a current operating mode based on changes in at least one of the first and second engine parameters. In a variable compression ratio (VCR) engine embodiment, the system and method modify ignition timing of at least one cylinder until engine knock is detected and determine whether the cylinder is operating in the lower compression ratio mode or the higher compression ratio mode by comparing the ignition timing change required to cause engine knock to a corresponding threshold.
