Abstract: Methods and systems are provided for regulating evaporative emissions from a fuel system. In one example, a method may comprise spinning an engine unfueled responsive to a hydrocarbon concentration at a fresh air end of a fuel vapor canister increasing above a first threshold. The method may comprise spinning the engine to pull hydrocarbons away until a hydrocarbon concentration at a purge end of the fuel vapor canister, opposite the fresh air end, increases above a second threshold.

Abstract: Methods and systems are provided for indicating a restriction in a fuel system vapor recovery line. Responsive to such an indication, methods and systems are provided for taking mitigating actions such that an entirety of a vehicle fuel system and evaporative emissions system, including a fuel filler system, may be diagnosed as to a presence or absence of undesired evaporative emissions, even with the restriction in the vapor recovery line present. In this way, undesired evaporative emissions may be reduced or avoided, completion rates for such tests may be increased, and customer satisfaction may be improved.

Abstract: The present invention relates to a method for removing cesium in a clay mineral using hydrogen peroxide. According to the present invention, cesium in a clay mineral is removed using hydrogen peroxide, which serves to induce interlayer expansion of the clay mineral to allow a cation to easily enter an interlayer of the clay mineral, and thus cesium desorption efficiency can be further improved. Also, the method according to the present invention can be efficiently used to restore soil in residential areas widely contaminated with a radionuclide when a major accident such as Fukushima nuclear accident occurs as well as various sites of atomic energy facilities contaminated with a radionuclide. Also, since radiation-contaminated soil is treated with only hydrogen peroxide and cations, secondary environmental pollution caused by wastes can be significantly reduce and the waste disposing cost can also be saved.

Abstract: This disclosure is directed to vehicle fuel systems capable of isolating the energy within a fuel tank from the vehicle user. An exemplary fuel system may include a first valve located within a fuel inlet conduit and a second valve located within a vapor recovery recirculation line of the fuel system. The first and second valves may be controlled based on the pressure inside a fuel tank of the fuel system. Fuel may only be transferred into the fuel tank when the fuel tank is within a predefined threshold pressure range. A depressurization sequence of the fuel tank may be automatically initiated when a fuel door of the fuel system is moved to an open position. The positioning of the fuel door may be monitored by a fuel door position monitoring device.

Abstract: Methods and systems are provided for diagnosing a vehicle fuel system for a presence or absence of undesired evaporative emissions. In one example, a method comprises evacuating the fuel system of a vehicle to a variable vacuum target as a function of a volatility of fuel in a fuel tank positioned in the fuel system and a loading state of a fuel vapor storage canister configured for capturing and storing fuel vapors from the fuel tank. In this way, analysis of a pressure-bleedup portion of the diagnostic may be more reliable and completion rates of the diagnostic may be improved, while conducting the test in an environmentally fashion.

Abstract: Methods and systems are provided for regulating fuel flow in a fuel tank. In one example, a method may comprise fueling a fuel tank by receiving a nozzle into a filler tube which extends into a fuel tank to fuel the fuel tank, and directing fuel through the tube against vanes in a baffle which forms a compartment within the tank. Additionally, the method may comprise enabling the vanes to open so that pressure within the compartment remains below a level which would otherwise cause shut off the nozzle during the fueling.

In one example, during a plug-in event to recharge a battery of the vehicle, the fuel tank is isolated and the fuel pump is actuated to agitate fuel within the tank and increase fuel vapors until the plastic fuel tank becomes aged to a predetermined degree by fuel vapors generated therein. In this manner, the fuel tank is aged more rapidly, resulting in more accurate fuel level readings and less noise and vibration.

The radionuclide absorbent, compared to conventional zeolite, may more selectively remove radioactive cesium (Cs+) and/or strontium (Sr2+) ions even in the presence of various competitive ions (e.g., Na+, K+, Mg2+, and Ca2+) in groundwater or seawater. In addition, the radionuclide absorbent may be prepared by a simple method of thermally treating a mixture of sulfur and zeolite, and thereby, sulfur may be uniformly dispersed in zeolite.
