Abstract:
An engine control system for an auto-stop/start vehicle includes a mode control module and an actuator control module. The mode control module selectively initiates an engine startup event when an engine startup command is generated. The actuator control module cranks an engine during the engine startup event, provides fuel to a first cylinder of the engine while the engine is being cranked, and selectively disables fuel to a second cylinder of the engine while the engine is being cranked. The second cylinder is after the first cylinder in a firing order.
