Abstract

A method for controlling regeneration within an after-treatment component of an engine comprises receiving a signal indicative of whether the engine is in an operating state or a non-operating state and detecting, based on the signal, when the engine has departed an operating state and entered a non-operating state. When the engine has departed an operating state and entered a non-operating state, a regeneration event is initiated. The regeneration event comprises causing a stream of air to flow through the after-treatment component and initiating a flow of fuel into the stream of air.
