Methods and systems are provided for regenerating an after-treatment system of a vehicle. A first operational parameter of a first component of the after-treatment system is monitored and a second operational parameter, different to the first operational parameter, of a second component of the after-treatment system is monitored. It is determined if the first operational parameter of the first component is outside a first threshold range and if the second operational parameter is approaching a second threshold and, in response to the first operational parameter being outside the first threshold range and the second operational parameter being within the second threshold range, a regeneration sequence of the after-treatment system configured to regenerate at least the first component of the after-treatment system is initiated.

Systems and methods for maintaining aftertreatment capability during vehicle life

Methods and systems are provided for a bleed valve assembly for an engine. In one example, a method (or system) may include a fastener comprising a threaded shank received within a bore of the engine, a bleed bore within the fastener, and a bleed plug including a threaded portion received within the bleed bore of the fastener. The bleed plug may include an internal passage extending from one end of the bleed plug and a side port in fluidic communication with the passage so that when the bleed plug is in an open position fluid from an engine fluid chamber may flow through the passage of the bleed plug and out of the port.
