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

Abstract An aftertreatment system (100) comprises a first passageway (1 12a) to receive a first portion and a second passageway (1 12b) 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 sys...

Zusammenfassung:	Abstract An aftertreatment system (100) comprises a first passageway (1 12a) to receive a first portion and a second passageway (1 12b) 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 (250a) 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 (153, 155, 157, 159) 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 (170) 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.
