Abstract
The present application generally relates to a diesel engine and, more particularly, to a control system and method for an exhaust aftertreatment system for a locomotive diesel engine. In accordance with an embodiment of the present system, a two-stroke uniflow scavenged diesel engine system including an exhaust aftertreatment system is described for reducing NOX emissions and achieving desired fuel economy. More specifically, a system and method for controlling the exhaust aftertreatment system is provided. The present system being adapted to monitor and control select components of the exhaust aftertreatment system. Specifically, the control system may be adapted to control select components of an exhaust aftertreatment system to adaptively regulate filtration based on various operating conditions of the locomotive.
