Abstract:
An operation mode of an engine and after-treatment system is determined based on a reductant-to-fuel cost ratio. The operation mode optimizes fuel consumption and reductant consumption in an engine system including an internal combustion engine and a selective catalytic reduction (SCR) catalyst while satisfying a target emissions emission level.
