    • An exhaust treatment system is provided. The system may include a particulate trap configured to remove one or more types of particulate matter from an exhaust flow, the exhaust flow including at least a portion of a totality of exhaust gases produced by an engine. The system may further include a burner assembly configured to increase a temperature of gases in the exhaust flow at a location upstream from the particulate trap. The burner assembly may include an exhaust inlet oriented in a direction along a first axis and configured to direct the exhaust flow into the burner assembly and an exhaust outlet oriented in a direction along a second axis at an angle relative to the first axis, the exhaust outlet being configured to direct the exhaust flow out of the burner assembly toward the particulate trap. The burner assembly may also include a fuel injector having a longitudinal axis in substantial alignment with the second axis. In addition, the burner assembly may include a cylindrical combustion chamber member defining a combustion chamber, having a longitudinal axis in substantial alignment with the longitudinal axis of the fuel injector, and configured to house a flame that is fueled by the fuel injector within the combustion chamber. The burner assembly may further include an exhaust flow distribution member configured to substantially evenly distribute exhaust about the combustion chamber member and in a heat exchange relation to the combustion chamber member.
    • 提供排气处理系统。 该系统可以包括构造成从排气流中去除一种或多种类型的颗粒物质的微粒捕集器,该排气流包括由发动机产生的全部废气的至少一部分。 该系统可以进一步包括燃烧器组件,该燃烧器组件构造成在微粒捕集器上游的位置增加排气流中的气体的温度。 燃烧器组件可以包括沿着第一轴线的方向定向的排气入口并且构造成将排气流引导到燃烧器组件中,并且排气出口沿着第二轴线的方向以相对于第一轴线成一定角度定向,排气口 出口构造成将废气流引导到燃烧器组件朝向颗粒捕集器。 燃烧器组件还可以包括具有与第二轴基本对准的纵向轴线的燃料喷射器。 此外,燃烧器组件可以包括限定燃烧室的圆柱形燃烧室构件,其具有与燃料喷射器的纵向轴线基本上对准的纵向轴线,并且构造成容纳由燃料喷射器在燃烧中燃料的火焰 房间。 燃烧器组件还可包括排气流分配构件,其构造成基本均匀地分布燃烧室构件周围的排气并且与燃烧室构件以热交换关系。
