An engine and after treatment system comprising an engine with an exhaust line engaged to upstream after treatment components, the upstream after treatment components engaged to a selective catalytic reduction converter, a means for bypassing the upstream after treatment components to allow engine exhausts to warm a catalyst within the selective catalytic reduction converter.
