Claim 5:
6. A system for an engine, comprising:
a fuel injector; and
a controller with computer-readable instructions stored on non-transitory memory that when executed cause the controller to:
inject fuel during a first set of multiple injections via the fuel injector during an engine cycle, learning each of a first opening time of a first injection of the first set and a second opening time of a second injection of the first set as a function of an inter-injection spacing between the first injection and the second injection; and
inject fuel during a second set of multiple injections via the fuel injector during a subsequent engine cycle, adjust a third opening time of another first injection of the second set based on the learned first opening time, and adjusting a fourth opening time of another second injection of the second set based on the learned second opening time.
