摘要： An engine exhaust aftertreatment system including a selective catalytic reduction (SCR) system. The SCR system includes a reductant injection system configured to introduce a reductant into a exhaust stream of a engine, a SCR catalysts configured to reduce NOx in the presence of a reductant, and a SCR monitoring system configured to determine temperatures associated with the SCR system. The SCR system also includes a heat source configured to raise the temperature of the exhaust stream and a controller configured to operate the heat source to reach exhaust stream temperatures in the SCR system of at least about 400 degrees Celsius based on the temperature associated with the SCR system.

摘要： Fuel injectors having control passages with relatively large volumes may have limited responsiveness. The injector described herein may help to reduce the control passage volume and improve responsiveness by providing a chamber for receiving a fluid, a control valve, a flow passage, and an insert. The control valve may be moveable between a first position and a second position. The flow passage may extend between the control valve and the chamber, and the flow passage may define a first volume. The insert may be located within the flow passage, and the insert may occupy a second volume. The placement of the insert within the flow passage reduces the volume of the flow passage that is available to receive the fluid to a third volume equal to the first volume less the second volume.
摘要翻译： 具有相对较大体积的控制通道的燃料喷射器可能具有有限的响应性。 本文所述的喷射器可以通过提供用于接收流体的腔室，控制阀，流动通道和插入件来帮助减少控制通道体积并提高响应性。 控制阀可以在第一位置和第二位置之间移动。 流动通道可以在控制阀和腔室之间延伸，并且流动通道可以限定第一容积。 插入件可以位于流动通道内，并且插入件可以占据第二容积。 插入件在流动通道内的放置将可用于接收流体的流动通道的体积减小到等于第一体积的第三体积，而第二容积小于第二体积。
