Abstract: An exhaust treatment fluid system includes a tank housing for storing an exhaust treatment fluid. A suction tube includes a first end positioned within the housing. A first sensor is positioned within the tank housing for determining at least one of a fluid level and a concentration of the exhaust treatment fluid. A skirt is positioned in the tank to peripherally surround the first sensor.

Abstract: An exhaust treatment fluid system includes a tank housing for storing an exhaust treatment fluid. A suction tube includes a first end positioned within the housing and a second end in communication with a suction port of the housing. An elongated laminar flow device is secured to a discharge port of the housing such that exhaust treatment fluid flows along surfaces thereof as the exhaust treatment fluid is returned to the tank housing. The laminar flow device includes a non-circular cross-section.

Abstract: The present invention relates to engines having multiple hydraulic devices. For instance a multi-cylinder diesel engine might include both an a fuel injector and an engine compression release brake. Traditionally, each of these hydraulic devices has been controlled by an individual actuator control valve. However, engineers have learned that decreasing the number of engine components can increase engine robustness. In addition, engineers have learned that de-coupling fluid pressure to the needle valve member hydraulic surface from fluid pressure lines to other injector components can result in greater control of the injector. Therefore, the present invention utilizes a single actuator control valve to control both hydraulic devices for an engine cylinder and to provide independent control of fluid pressure to the needle valve member closing hydraulic surface.

Abstract: Engineers have determined that the ability to front end rate shape injection events can result in a number of advantages, including improved injector performance and a reduction in undesirable emissions. In addition, engineers have learned that it is desirable for the needle valve to open slowly at the beginning of an injection event and to close abruptly to end the injection event. Therefore, the present invention utilizes at least one orifice member that is movably positioned in an injector body such that fluid flowing away from the needle valve member closing hydraulic surface flows through a relatively restricted flow path and fluid flowing toward the needle valve member flow through a relatively unrestricted flow path.

Abstract: Particularly in an engine that has been inactive for a substantial period of time at a cold temperature, fluid forces acting on moving members, such as electronically-activated fluid control valves, may be significant until the engine warms up. A way to reduce the fluid forces and their detrimental effects is to reduce the volume of fluid which are creating the fluid forces, including venting all or some of this fluid to drain. Additionally, fluid that gathers can be drained away. In order to accomplish such venting, the present disclosure includes a fluid control valve having a body with at least one fluid passage connected to a bore, a movable member in the bore, an actuator connected to the movable member to move the movable member, and at least one vent passage opening into the bore between the fluid passage and the actuator. The disclosure may include additional drain passages to drain away gathered fluid from actuating components.
