Abstract | A system and method for controlling operation of an internal combustion engine having at least one fuel injector. A controller is configured to selectively command the at least one fuel injector to deliver a primary fuel injection of a first fuel quantity and a secondary fuel injection of a second fuel quantity. The first fuel quantity is above a predefined threshold and the second fuel quantity is at or below the predefined threshold. The controller is configured to command a primary pulse width and a secondary pulse width, based in part on a respective desired fuel injection mass and respective initialized values of fuel injector slope. Operation of the fuel injectors is controlled based in part on a converged primary fuel injector slope and a converged secondary fuel injector slope determined at partially from a comparison of a calculated fuel mass and an estimated fuel mass. |
