Classification: CPC F  Y | IPC F

Claim 0:
1. An aftertreatment system, comprising:
a selective catalytic reduction catalyst including a vanadium substrate structured to receive first exhaust gas from a first fuel source of a dual fuel engine system and second exhaust gas from a second fuel source of the dual fuel engine system, a first fuel of the first fuel source differing from a second fuel of the second fuel source;
an ammonia slip catalyst positioned downstream of the selective catalytic reduction catalyst to receive a flow of exhaust gases from the selective catalytic reduction catalyst without an intervening catalyst;
an oxidation catalyst positioned downstream of the ammonia slip catalyst to receive the flow of exhaust gases from the ammonia slip catalyst without an intervening catalyst; and
one or more processing circuits configured to control the dual fuel engine system, the one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
send a feedback substitution rate command to the dual fuel engine system based on a system out emissions value to control operation of the dual fuel engine system using a feedback substitution rate that is updated based on a substitution rate table.
