Abstract
A vehicle includes a combustion engine having at least one cylinder to burn a fuel, and a fuel injector to supply a fuel mass to the at least one cylinder. The vehicle also includes a controller programmed to cause the fuel injector supply a series of fuel pulses that sum to an aggregate target fuel mass. The controller is also programmed to adjust a commanded duration of a subsequent pulse of the series of pulses from a target pulse duration value based on at least one of a dwell time since a preceding pulse, a fuel mass of the preceding pulse, and an opening delay of the preceding pulse.
