Abstract
Official abstract text for this publication.
An engine command override may occur when a diesel particulate filter (DPF) requires regeneration. The need for regeneration may be indicated by regeneration level. The engine may be operated in a normal mode when the DPF regeneration level is below a regeneration level threshold, wherein the engine command is based on the throttle input. Additionally, the engine may be operated in an override mode when the DPF regeneration level is above a regeneration level threshold and the engine is operating in the idle state, wherein the engine command is based on a predetermined throttle regeneration setting.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of automatically controlling an engine to override a throttle input setting and operate at a predetermined throttle regeneration setting sufficient to initiate a regeneration event for a diesel particulate filter associated with a machine and operably coupled to the engine, the engine including a controller configured to generate an engine command setting, the method comprising: determining a DPF regeneration level indicative of a need to regenerate…
