Abstract
A system, apparatus, and method are disclosed for controlling a fuel injector using multipulse fuel injection. According to at least one aspect of the present disclosure, the system includes a fuel sequence controller configured for use with a fuel injector having an injector configuration modeled by a body pressure characteristic that includes a rail pressure and an injection rate shape, where the fuel sequence controller is structured to determine an estimate of the injected fuel quantity delivered from the fuel injector at the determined body pressure characteristic.
