摘要： A fuel system component may include a body arranged for use in storing or moving fuel within the fuel system, and an indicator associated with the body to provide an indication when the body is subjected to a condition outside of a threshold. The indicator may be responsive to one or more environmental or system conditions outside of a threshold. For example without limitation, the indicator may be responsive to one or more of temperature, pressure, corrosion and electrical conditions to provide an indication when at least one condition exceeds a threshold for that condition.

摘要： A high flow rate, two stage fuel vapor vent valve assembly utilizing two float valves that provide a progressive closing of a vapor outlet to control the venting of fuel vapors from a fuel tank and the addition of liquid fuel to the tank. A first float closes a portion of the vapor outlet in response to liquid fuel at a first level relative to the valve. A second float closes the remainder of the vapor outlet in response to liquid fuel at a second level higher than the first level. One or more separate baffles are constructed and arranged to prevent the escape of liquid fuel through the vapor outlet.

摘要： A fluid distribution system may include a by-pass fluid filter that combines high volume, in-tank fluid filtration with low volume fluid delivery to an external device such as an SCR injector. One or more outlet ports located along the fluid filter housing can be configured to discharge fluid toward other fluid distribution system components. In systems such as SCR systems, where the liquid reducing agent may freeze when not in use, directing already thawed liquid toward other system components can help thaw the frozen reducing agent at desired locations first. The fluid distribution system can also be arranged so that flow through the filter is in the same direction during the distribution cycle and during the purge cycle.

摘要： A fluid distribution system of a selective catalytic reduction (SCR) system may include a storage tank and a fluid distribution module disposed at least partially within the storage tank. The distribution module includes a pump assembly comprising a fluid pump having a pump inlet configured to receive liquid from an inner volume of the tank, and a pump outlet fluidly connected to a module outlet port. The distribution module further includes a fluid discharge jet fluidly connected to the pump outlet and operable to discharge liquid from the pump outlet and into the tank volume. In an exemplary embodiment, the distribution module still further includes a valve disposed between the pump outlet and the discharge jet operable to selectively allow liquid fluid flow from the pump outlet to the discharge jet when one or more predetermined criteria are met.

摘要： A selective catalytic reduction system includes a fluid distribution system for supplying an exhaust gas reducing agent. The system includes a liquid storage tank and a fluid distribution module with a fluid pump that draws liquid reducing agent from the tank volume and provides the liquid at a module outlet port, while simultaneously discharging excess liquid from a circulation line outlet within the tank volume. The circulation line outlet can be located at a bottom portion of the tank volume near other distribution module components to promote liquid circulation around the module components during a fluid distribution period, to promote thawing of frozen reducing agent at and around the module components, and to ensure a continuous supply of liquid to the fluid pump. The distribution module is also capable of purging liquid from fluid lines located outside the storage tank and returning the purged liquid to the tank volume.

摘要： In at least some implementations, a fluid level sensor for sensing the level of a fluid within a tank includes a fluid tube through which fluid flows under pressure, a pressure pulse inducer, a fluid level responsive member and a pressure sensor. The pressure pulse inducer is disposed within the fluid tube so that at least some of the fluid flowing through the fluid tube engages the pressure pulse inducer. The fluid level responsive member is operably associated with the pressure pulse inducer to provide a force on the pressure pulse inducer that varies as a function of the fluid level in the tank. And the pressure sensor at senses the pressure of the fluid flowing through the tube, where the pressure pulse inducer induces changes in the pressure of the fluid as a function of the fluid level and the changes in pressure are sensed by the pressure sensor.

摘要： A method of relieving hot soak pressure in a fuel rail of a fuel injected internal combustion engine includes pressurizing fuel with a fuel pump when the engine is operating, and conveying the pressurized fuel through a check valve that prevents backflow of fuel from the fuel rail toward the fuel pump. A bypass path is in fluid communication between a location downstream of the check valve and a location downstream of the fuel pump and upstream of the check valve. The bypass path is opened when the engine is not operating so as to relieve fuel pressure downstream of the check valve to a level below a system operating pressure. Apparatuses are provided for carrying out the method.
