    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 steady-state (SS) delay module determines a SS delay period for SS operating conditions based on an air per cylinder. A dynamic compensation module determines a predicted delay period based on first and second dynamic compensation variables for dynamic operating conditions, the SS delay period, a previous predicted delay period. The first dynamic compensation variable corresponds to a period between a first time when fuel is provided for a cylinder of an engine and a second time when exhaust gas resulting from combustion of the fuel and air is expelled from the cylinder. The SS and predicted delay periods correspond to a period between the first time and a third time when the exhaust gas reaches an exhaust gas oxygen sensor located upstream of a catalyst. A final equivalence ratio module adjusts fuel provided to the cylinder after the third time based on the predicted delay period.
