Single sensor monitoring system for multiple after-treatment systems on engines

An aftertreatment system comprises a first passageway to receive a first portion and a second passageway to receive a second portion of the exhaust gas from the engine. The first and second passageways can have the same length. A first selective catalytic reduction system is fluidly coupled to the f...

Beschreibung
Zusammenfassung:	An aftertreatment system comprises a first passageway to receive a first portion and a second passageway to receive a second portion of the exhaust gas from the engine. The first and second passageways can have the same length. A first selective catalytic reduction system is fluidly coupled to the first passageway to receive and treat the first portion. A second selective catalytic reduction system is fluidly coupled to the second passageway to receive and treat the second portion. A plurality of sensors are disposed on the first passageway and/or the first selective catalytic reduction system to sense operational parameters of the first portion of the exhaust gas. A controller is in electronic communication with the plurality of sensors to determine the operational parameters of the first portion and to determine operational parameters of the second portion of the exhaust gas based upon the first operational parameters.
