摘要

A power system comprising an engine that produces exhaust, a particulate filter that traps soot from the engine, and a controller that switches the power system from a first operation mode into a second operation mode to regenerate the particulate filter wherein a transition between the first operation mode and the second operation mode occurs at a slower rate when an amount of soot in the particulate filter changes relative to a threshold than when a load on the engine changes.
