Abstract: An electrically adjustable hydraulic shock absorber includes a piston positioned within a tube that divides a fluid chamber into a first working chamber and a second working chamber. A piston rod is attached to the piston and projects. An electronically-controlled valve is positioned within a rod guide. A circuit board is in communication with the electronically-controlled valve. A carrier includes an inner wall and an outer wall interconnected by a bottom wall thereby defining a pocket. A circuit board is positioned within the pocket.

Abstract: A waste heat recovery system may include a pump, first and second heat exchangers, an expander, and a valve. The first heat exchanger receives working fluid from the pump. The expander receives working fluid from the first heat exchanger and includes an output shaft that is powered by the flow of working fluid through the expander. The second heat exchanger may include a first fluid path and a second fluid path that is shorter than the first fluid path. The valve controls fluid flow through the first and second fluid paths. A sensor may measure a parameter of the working fluid that indicates whether the working fluid is in a gaseous state, a liquid state or a mixture of gas and liquid. A control module in communication with the sensor may control a position of the valve based on a value of the parameter measured by the sensor.

Abstract: An exhaust aftertreatment system may include a tank, an injector, a supply conduit, a pump, a pressure sensor, and a control module. The tank may contain a volume of a fluid. The injector may be configured to inject the fluid into a stream of exhaust gas discharged from the combustion engine. The supply conduit may fluidly connect the tank and the injector. The pump may pump the fluid from the tank to the injector. The control module may be in communication with the pressure sensor and the pump and may control the pump based on first and second measurements from the pressure sensor. The first measurement may be indicative of a first pressure within the supply conduit when the pump is operating. The second measurement from the pressure sensor may be indicative of a second pressure within the supply conduit when the pump is not operating.

Abstract: A system for treating the exhaust output by an internal combustion engine includes a regeneration positioned upstream from a diesel particulate filter. The regeneration unit combusts a fuel to heat the exhaust entering the diesel particulate filter. An air pump supplies a secondary source of compressed air to the regeneration unit and is adapted to be driven by the internal combustion engine. A speed sensor is coupled to the air pump and operable to output a signal indicative of a rotational speed of an air pump component. A controller receives the speed sensor signal and determines an operating speed of the internal combustion engine based on the speed sensor signal. The controller controls the regeneration unit based on the engine operating speed.

Abstract: A system for controlling the temperature of an exhaust stream from an engine at a location upstream from an exhaust aftertreatment apparatus 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. An ion sensor is operable to output a signal indicative of the presence of fuel combustion. A controller selectively operates the regeneration unit to increase the exhaust temperature. The controller is operable to control a supply of fuel to the regeneration unit based on the ion sensor signal.
