Systems and methods may be provided for monitoring a fuel level of a vehicle. The fuel may be a gaseous fuel, such as natural gas. An electronic control unit may be able to receive a signal from one or more sensors. The electronic control unit may provide a command to drive a fuel gauge to display the fuel level. The electronic control unit may determine the gauge command based on the received signal and a filling compensation scheme. The electronic control unit may be initialized through a user interface. A filling compensation scheme may be selected during initialization. The electronic control unit may be capable of communicating various sensors, gauges, devices, controls and/or other ECUs of varying specifications.

An integrated cryogenic fluid delivery system includes a cryogenic liquid tank having an interior, a wall and a geometry. The interior of the cryogenic liquid tank contains a supply of cryogenic liquid. A fuel pickup line is positioned within the interior of the tank and is in fluid communication with a vaporizer so that the vaporizer receives and vaporizes cryogenic liquid from the tank. The vaporizer is positioned outside of the tank and is secured to the wall. The vaporizer also has a shape that conforms with the geometry of the tank.

A fuel level measurement system and method for liquified natural gas (LNG) powered machines is disclosed. An engine control module (ECM) receives fuel line pressure levels at a first time (e.g., a key-off event) and, again, at a second time (e.g., a key-on event). The ECM predicts an expected change in pressure from the key-off event to the key-on event based on various factors. If the change in pressure detected is greater than a threshold level different from the predicted change in pressure, the ECM determines a fill event and resets a current fuel level. The ECM tracks mass flow commands used to provide fuel to the engine to determine the consumption of fuel from the fuel tank and to determine a new current fuel level based on the amount of fuel consumed. The current fuel level is displayed on a fuel gauge.

An integrated fill system is provided for a vehicle. The integrated fill system can include a receptacle, a cap that mates with the receptacle, and a fill line that is in fluid communication between the receptacle and a container. The integrated fill system can further include a valve between an opening on an end of the container and an end of the fill line to allow one-way fluid communication for entry of compressed material into the container. The integrated fill system can further include a draw line on an opposite end of the container to maintain separate lines for filling and drawing compressed material into/from the container.

The invention relates to a system for supplying a gaseous fuel that comprises a low temperature tank for receiving the fuel in its liquid aggregate state achieved by cooling and comprises a rail that is fluidically connected to at least one injector device for discharging gaseous fuel into a combustion space. The system is characterized in that it has a pressure store that is configured to receive gaseous fuel and that is fluidically connectable to both the low temperature tank and the rail to buffer fuel coming from the low temperature tank and to supply it to the rail.

A device for monitoring the use of a pressure container system of a piece of equipment, such as a motor vehicle, is designed to ascertain equipment-side usage data relating to previous use of the pressure container system. The device is additionally designed to compare the equipment-side usage data with equipment-external usage data relating to the previous use of the pressure container system and to initiate one or more measures relating to further use of the pressure container system on the basis of the comparison.
