Abstract
A control system for an engine includes a parameter determination module and a period determination module. The parameter determination module determines a first fuel injection parameter based on a rate of change of a quantity of fuel injected during a period, and determines a second fuel injection parameter based on an initial quantity of fuel injected during the period. The period determination module determines a desired fuel injection period based on a desired fuel injection quantity, the first and second fuel injection parameters, and at least one of mass air flow (MAF) rate, intake air temperature (IAT), fuel injector pressure (FIP), engine coolant temperature (ECT), and exhaust gas air/fuel (A/F) ratio.
