    摘要: A fuel control system for regulating fuel to cylinders of an internal combustion engine during an engine start and crank-to-run transition includes a first module that determines a raw injected fuel mass based on a utilized fuel fraction (UFF) model and a nominal fuel dynamics (NFD) and a second module that regulates fueling to a cylinder of the engine based on the raw injected fuel mass until a combustion event of the cylinder. Each of the UFF and NFD models is calibrated based on data from a plurality of test starts-that are based on a pre-defined test schedule.

    摘要: A fuel control system for regulating fuel to cylinders of an internal combustion engine during an engine start and crank-to-run transition includes a first module that determines a plurality of step-ahead cylinder air masses (GPOs) for a cylinder based on a plurality of GPO prediction models. A second module regulates fueling to a cylinder of the engine based on the plurality of step-ahead GPOs until a combustion event of the cylinder.

    摘要: An engine control system for an auto-stop/start vehicle, comprising: an actuator control module, a correction determination module, and a spark adjustment module. The actuator control module determines a target spark timing for a first time that is between a second time when engine cranking begins and a third time when a measured engine speed becomes greater than a predetermined engine speed after the second time. The correction determination module determines a spark timing correction for the first time based on a target engine speed and a measured engine speed. The spark adjustment module sets a spark timing for the first time based on the target spark timing and the spark timing correction.

    摘要: An engine control system for an auto-stop/start vehicle includes an auto-stop/start module and an actuator control module. The auto-stop/start module selectively generates an auto-stop command for shutting down an engine while an ignition is in an ON state. The actuator control module disables fuel to the engine when the auto-stop command is generated and closes a throttle valve to a predetermined throttle opening when the auto-stop command is generated.
