  • Selective catalytic reduction warmup system
    Patent number: 9840956
    Abstract: 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. One version allows indirect warming of the catalyst by providing a pathway for engine exhausts thru a warming cavity located on an outer region of the selective catalytic converter and then back thru the upstream after treatment components.
    Type: Grant
