Abstract:
1. A method of determining an amount of fuel to include within exhaust gases to facilitate regeneration of a particulate filter, the particulate filter being in fluid communication with an engine to capture particulates emitted in exhaust gases therefrom, the method comprising: determining a first fuel injection value as a function of an open loop fuel injection control strategy; determining a second fuel injection value as a function of a closed loop fuel injection control strategy; adjusting the first fuel injection value as a function of the second fuel injection value; determining a third fuel injection value as function of an open loop emissions fuel injection control strategy; and determining the amount of fuel to include within the exhaust gases to facilitate regeneration of the particulate filter as a function of the adjusted first fuel injection value and the third fuel injection value.
