摘要：PROBLEM TO BE SOLVED: To provide a urea injection control system for exhaust aftertreatment.SOLUTION: A selective catalytic reduction (SCR) catalyst 135 is in fluid communication with an exhaust stream generated from an engine 105. An oxidation catalyst (OC) 115 is upstream of the SCR catalyst 135 and in fluid communication with the exhaust stream. A gaseous reductant injector 125 is upstream of the SCR catalyst 135, downstream of the OC 115, and in fluid communication with the exhaust stream. A first gas sensor 145 is upstream of the OC, and a second gas sensor 145 is downstream of the SCR catalyst 135. A controller 155 receives signals representative of gas concentrations detected in the exhaust stream by the first gas sensor 145 and the second gas sensor 145, and estimates concentrations of nitric oxide (NO) and nitride dioxide (NO) in the exhaust stream from the gas concentrations.
