摘要： A system for treating an exhaust stream from an engine includes a main exhaust passageway adapted to receive the exhaust stream from the engine. A side branch is in communication with the main exhaust passageway. A regeneration unit is positioned within the side branch for combusting a fuel and heating the exhaust flowing through the main exhaust passageway. A lean NOx catalyst is positioned within the main exhaust passageway downstream of the regeneration unit. A reductant injector is positioned downstream of the regeneration unit and upstream of the lean NOx catalyst to inject reductant particles into the exhaust stream. A controller operates the regeneration unit to increase the exhaust temperature as well as operates the reductant injector to reduce NOx within the lean NOx catalyst.

摘要： An emissions system for reducing nitrogen oxides in engine exhaust includes an emissions catalyst having an inlet adapted to receive an exhaust from the engine. A fuel tank is adapted to provide fuel for combustion within the engine. A first injector is operable to inject fuel into the exhaust upstream of the catalyst. A second injector is operable to inject supplemental reductant from a supplemental reductant tank into the exhaust upstream of the catalyst. A controller is operable to control the first and second injectors and vary the supply of fuel and supplemental reductant into the exhaust to reduce nitrogen oxides within the exhaust.

摘要： In one arrangement the data is transmitted from the first transceiving station to the second transceiving station according to a frame structure comprising a payload portion for transmitting payload data and a synchronisation portion for transmitting synchronisation data. The frame structure is selected from candidate frame structures, the candidate frame structures having differing durations of the synchronisation portion, according to a data loading factor, the data loading factor depending on the amount of data that is required to be transmitted. Thus in embodiments of the invention the payload capacity may be optimised by reducing the duration of the synchronisation portion when a large amount of data is required to be transmitted.
摘要翻译：在一种布置中，根据包括用于发送有效载荷数据的有效载荷部分和用于发送同步数据的同步部分的帧结构，将数据从第一收发站发送到第二收发站。从候选帧结构中选择帧结构，根据数据加载因子，候选帧结构具有不同持续时间的同步部分，数据加载系数取决于需要发送的数据量。因此，在本发明的实施例中，可以通过在需要发送大量数据时减少同步部分的持续时间来优化有效负载容量。
