Abstract
A power system comprising an engine that produces exhaust, a fuel system that injects a fuel into the engine, an aftertreatment system that treats the exhaust, and a controller. The aftertreatment system includes an oxidation catalyst that converts NO from the engine into NO2, a particulate filter that traps soot from the engine, and a sensor that provides an indication of the amount of soot in the particulate filter. The controller increases an engine fuel injection pressure when the amount of soot in the particulate filter is above a threshold.
