    摘要： One concept relates to power generation system, comprising a diesel engine, an exhaust manifold, a turbocharger, and an exhaust line in which are configured a fuel reformer and a LNT. A fuel injector is configured to inject fuel into the manifold upstream of the turbine. The high temperatures upstream of the turbine cause the fuel to crack into smaller molecules, releasing heat and providing a boost to the turbocharger. The fuel injected into the manifold also undergoes intense mixing as it passes through the turbocharger. Injecting fuel in this manner provides several benefits for reformer operation. Another concept relates to a manifold fuel injector used to provide fuel for heating a DPF.

    摘要： Rhodium utilization in LNT/SCR-based exhaust after treatment systems for medium and heavy duty trucks is reduced by operating inline fuel reformers in a certain manner. The fuel processors are operated at steam reforming temperatures to produce a reformate-containing exhaust having a hydrogen to CO ratio of at least about 3:2 or at least about 3% hydrogen, This generally involves operating the fuel reformers at temperatures from about 500 to about 625° C. and with an overall fuel to air ratio from about 1.10 to about 1.40. In this manner, regeneration can be efficiently carried out while limiting the catalyst loading of the fuel processors to no more than about 1.0 grams rhodium per liter maximum displacement of the diesel engine and the catalyst loading of the LNTs to no more than about 0.50 grams rhodium per liter maximum displacement of the diesel engine.
