Abstract
A method of operating an exhaust gas after-treatment device with a substrate having a catalyst thereon directs exhaust gas through a first portion of the substrate during a cold-start of the after-treatment device, where the first portion of the substrate less than an entirety of the substrate. After light-off of the catalyst in the first portion of the substrate, exhaust gas is directed through the entirety of the substrate. An exhaust gas after-treatment device for carrying out the method includes a flow control device having a cold start configuration and a light off configuration, wherein the cold start configuration directs exhaust gas through the first portion of the substrate, and the light off configuration directs exhaust gas through the entirety of the substrate.
