摘要： A fuel reforming system includes an inlet device for a reactor having a housing defining a frustoconical interior region having an inlet opening and an outlet opening. A tube mixer having a helical divider may be optionally employed to transfer fluid into the inlet opening. A retention member is placed at each of the openings and a plurality of particles is contained within the frustoconical interior region between the retention members. An insulator placed between the outlet opening and the catalyst reaction surface minimizes temperature non-uniformities over the catalyst surface area, which preserves the catalyst contained within the reaction surface and prevents premature onset of the reaction prior to contact of a reactant mixture with the reaction surface. As a reactant fluid material passes through the inlet device it forms a homogenous reactant fluid material which then flows onto a catalytic reaction surface to form a reformate. Even distribution of the reactant fluid material onto the catalyst reaction surface provides uniform reactivity of the various components (e.g. fuel, air and exhaust gas mixture) comprising the reactant mixture, which helps reduce carbon build-up in the system and increases thermal efficiency.
摘要翻译：燃料重整系统包括用于反应器的入口装置，其具有限定具有入口开口和出口开口的截头圆锥形内部区域的壳体。可以任选地使用具有螺旋分隔器的管式混合器将流体输送到入口开口中。保持构件被放置在每个开口处，并且多个颗粒包含在保持构件之间的截头圆锥形内部区域内。放置在出口和催化剂反应表面之间的绝缘体使催化剂表面积上的温度不均匀性最小化，这保留了反应表面内含有的催化剂，并防止反应物与反应表面接触之前的过早开始。当反应物流体材料通过入口装置时，其形成均匀的反应物流体材料，然后流入催化反应表面以形成重整产物。反应物流体材料在催化剂反应表面上的均匀分布提供包含反应物混合物的各种组分（例如燃料，空气和废气混合物）的均匀反应性，这有助于减少体系中的碳积累并提高热效率。

摘要： An engine control system for a vehicle includes an oxygen mass flow rate module, an oxygen per cylinder module, and a fuel control module. The oxygen mass flow rate module generates a mass flow rate of oxygen flowing into an engine based on a mass air flow rate (MAF) into the engine and a percentage of oxygen by volume measured using an intake oxygen (IO) sensor in an intake system. The oxygen per cylinder module generates a mass of oxygen for a combustion event of a cylinder of the engine based on the mass flow rate of oxygen flowing into the engine. The fuel control module controls fueling to the cylinder for the combustion event based on the mass of oxygen.

摘要： The present invention is an aftertreatment system for lean burn internal combustion engines. The present invention provides a multiple branch lean NOx trap, or LNT, with a diverter valve operable to selectively direct lean exhaust flow to one portion of the LNT while another portion of the LNT regenerates in a low oxygen environment. Additionally, the present invention employees a continuously operating side stream exhaust fuel reformer that delivers a reductant, such as partially oxidized (POx) gas or reformate, to the LNT for regeneration. The present invention also provides a method of exhaust aftertreatment of a lean burn internal combustion engine utilizing the system provided.

摘要： A thin layer of low mean-pore-size filter material that permanently accommodates the accumulation of exhaust particulates (as soot or a soot cake) is carried on a porous ceramic support. The supported filter material is closely coupled with the exhaust manifold of the engine, for the purpose of passive regeneration of stored particulates, and removes particulate matter from the exhaust which is directed through the filter layer and ceramic support. The oxygen content of the exhaust oxidizes the particulate matter on the filter material. In a preferred embodiment, a thin layer of the filter material is supported on inlet channel walls of a wall flow-through ceramic filter body to remove the particles from the exhaust. The filter body comprises an upstream exhaust gas flow inlet face with openings to a plurality of inlet channels and a downstream face with a like plurality of openings from outlet channels. The inlet channels are closed at the downstream face and the outlet channels are closed at the inlet face. So the exhaust stream enters the inlet channels and flows through the filter layers and supporting channel walls to an outlet channel. The filtered exhaust stream exits the outlet end of the filter body and is combined into an exhaust passage downstream of the filter body for further treatment as may be necessary.
