determining, by a processing unit, a fueling interaction quantity indicating an amount of fueling interaction between a pilot pulse and a main pulse of a multipulse fuel injection event;

determining, by the processing unit, an adjustment to be made to the pilot pulse or the main pulse using a fueling interaction model involving the multipulse fuel injection event based on the amount of fueling interaction, the determining including (a) in response to a target main injection pulse quantity exceeding the fueling interaction quantity, subtracting the fueling interaction quantity from the target main injection pulse quantity to determine a first adjusted fuel quantity as the adjustment and (b) in response to the target main injection pulse quantity not exceeding the fueling interaction quantity subtracting the target main injection pulse quantity from the fueling interaction quantity and adding an adjustment term to determine a second adjusted fuel quantity differing from the first adjusted fuel quantity as the adjustment; and

performing, by the processing unit, the determined adjustment on the pilot pulse or the main pulse.
