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： 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.

摘要： This disclosure relates to a fuel injector for an internal combustion engine. The injector comprises an injector body forming a plunger bore, and a plunger reciprocably mounted in the bore. The plunger reciprocates between a retracted position and a forward position, and a fuel receiving or metering chamber is formed at the forward end of the bore when the plunger is in the retracted position. A fuel supply passage is formed in the body and conducts fuel to the chamber when the plunger is in the retracted position. When the plunger is moved forwardly in an injection stroke, it ejects the fuel from the chamber through spray holes formed in the body. The injector further includes means for selectively opening or closing the supply passage when the injector plunger is in the retracted position. Such means includes a land formed on the plunger adjacent the supply passage, a groove formed in the land, and means for rotating the plunger between two angular positions. When the plunger is retracted and the plunger is in one angular position, the groove connects the supply passage to the chamber and in the other position the groove is displaced from the passage and the land closes the passage.
摘要翻译：本公开涉及一种用于内燃机的燃料喷射器。喷射器包括形成柱塞孔的喷射器主体和可往复运动地安装在孔中的柱塞。柱塞在缩回位置和向前位置之间往复运动，并且当柱塞处于缩回位置时，在孔的前端处形成燃料接收或计量室。燃料供给通道形成在主体中并且当柱塞处于缩回位置时将燃料传导到腔室。当柱塞在注射行程中向前移动时，其通过在体内形成的喷孔将燃料从腔室喷出。喷射器还包括当喷射器柱塞处于缩回位置时选择性地打开或关闭供给通道的装置。这种装置包括形成在柱塞上的与供给通道相邻的台面，形成在槽脊中的槽，以及用于在两个角位置之间旋转柱塞的装置。当柱塞缩回并且柱塞处于一个角度位置时，凹槽将供应通道连接到室，并且在另一位置，凹槽从通道移位，并且平台关闭通道。
