Abstract
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.
