Abstract: A shock absorber has a pressure tube with a piston assembly slidably disposed within the pressure tube and attached to a piston rod. The piston assembly divides the pressure tube into an upper working chamber and a lower working chamber. The piston assembly includes a frequency dependent valve assembly attached to the piston rod which defines a housing attached to the piston rod and a piston disposed within the housing. The piston moves within the housing to control the fluid flow through a bypass fluid passage that bypasses the piston assembly.

Abstract: An exhaust aftertreatment system may include an oxidation catalyst, a soot sensor, a filter and a control module. The oxidation catalyst may be disposed in an exhaust gas passageway and may receive exhaust gas discharged from an engine. The soot sensor may be at least partially disposed in the exhaust gas passageway downstream of the oxidation catalyst. The filter may be disposed in the exhaust gas passageway downstream of the soot sensor. The control module may be in communication with the soot sensor and may determine a face-plugging condition of the oxidation catalyst based on data received from the soot sensor.

Abstract translation: 废气后处理系统可以包括氧化催化剂，烟灰传感器，过滤器和控制模块。 氧化催化剂可以设置在废气通道中并且可以接收从发动机排出的废气。 煤烟传感器可以至少部分地设置在氧化催化剂下游的废气通道中。 过滤器可以设置在煤烟传感器下游的废气通道中。 控制模块可以与烟尘传感器连通，并且可以基于从烟灰传感器接收的数据来确定氧化催化剂的面部堵塞状况。
