Abstract:
1. A turbocharger mixing manifold for promoting a uniform mixture and distribution of exhaust gas into a filtration system of an exhaust aftertreatment system for reducing pollutants in exhaust gas expelled from a locomotive diesel engine, the turbocharger mixing manifold comprising: a mixing manifold intake coupled to a turbocharger and adapted to receive exhaust gas expelled from the locomotive engine via the turbocharger; a mixing manifold outlet for directing the exhaust gas into said filtration system of said exhaust aftertreatment system; a mixing chamber, sized and shaped to promote a stable and uniform flow field of exhaust gas allowing for a thorough mixing of exhaust gas and for even distribution of the exhaust gas to said filtration system via said mixing manifold outlet; and a heating device and DOC/DPF dosers, wherein the heating device includes an outlet positioned so as to introduce the heated exhaust gas downstream of the flow field of the exhaust gas entering said mixing chamber at said mixing manifold intake but upstream from the location of said DOC/DPF dosers for injecting fuel into said mixing chamber.
