摘要： Urea injection system wash cycle methods and systems are disclosed. An exemplary wash cycle method includes operating a urea injection system to provide urea solution to a first inlet of a blending chamber, provide pressurized gas to a second inlet of the blending chamber, and output a combined flow of pressurized gas and urea solution from the blending chamber. A pressure of the combined flow at a location downstream from the first inlet and the second inlet is monitored. A wash cycle is performed based upon the monitored pressure wherein the flow of pressurized gas is turned off and urea solution is provided to the blending chamber. An exemplary system includes a controller configured to control a urea injection system to perform a wash cycle in accordance with the exemplary method.

摘要： Apparatuses and methods for urea dosing of an exhaust after treatment system are disclosed. Exemplary apparatuses include a chamber configured to receive pressurized gas at a first inlet, receive urea solution at a second inlet, and provide a combined flow of pressurized gas and urea to an outlet, a flow passage extending from the first inlet to a seating surface, and a valve member configured to move between an open position in which the valve member is spaced apart from the seating surface and a closed position in which the valve member contacts the seating surface. As the valve member moves from the open position to the closed position the valve member contacts the seating surface at a first location and wipes an area of the seating surface extending from the first location in a direction toward the flow passage.

摘要： A system includes a cylindrical blend chamber having two inlets and one outlet. The outlet is fluidly coupled to a transfer line, and a nozzle is positioned downstream of the transfer line. The nozzle is fluidly coupled to an exhaust stream of an internal combustion engine. The system further includes a first inlet fluidly coupled to a diesel exhaust fluid (DEF) stream, and a second inlet fluidly coupled to an air stream. The DEF stream and the air stream intersect at a divergent angle.

摘要： Urea solution pumps having leakage bypass flowpaths and methods of operating the same are disclosed. Certain embodiments are pump apparatuses including an inlet passage in flow communication with a source of urea solution and a pump chamber, an outlet passage in flow communication with the pump chamber and an exhaust after treatment system, a diaphragm facing the pump chamber and coupled with an actuator, a first housing member coupled with a second housing member form a seal around the pumping chamber, a leak collection chamber surrounding the seal, and a return passage in flow communication with the leak collection chamber and the inlet passage. Urea solution that leaks from the pump chamber past the seal is received by the leak collection chamber and flows through the return passage to the pump inlet passage.
