A fuel system for a machine may include a fuel tank configured to hold cryogenic fuel, a pressure sensor, and an electronic control module (ECM). The ECM may determine a change in pressure of the fuel between a first time and a second time, determine a predicted change in pressure of the fuel between the first time and the second time, and determine that the change in pressure and the predicted change in pressure is greater than a threshold. Based on the change in pressure and the predicted change in pressure being greater than the threshold, a notification may be displayed associated with an integrity of the fuel tank.

A fuel storage and delivery system for a refrigerated cargo vehicle. The system includes a first fuel tank for storing natural gas and a second fuel tank for storing natural gas, at least the first fuel tank is for storing the natural gas as liquefied natural gas (LNG); a vehicle fuel supply line fluidly connected to the first fuel tank for supplying fuel from the first fuel tank to a vehicle engine; and a refrigeration unit fuel supply line fluidly connected to the second fuel tank for supplying fuel from the second fuel tank to a transport refrigeration unit engine.

A vehicle has a fuel system that includes a controller that determines when the vehicle is in a refuel mode or a run mode based on a connection of a refuel nozzle to a vehicle connection of the vehicle. The controller controls a fuel pump input selector, a vehicle fuel pump, and a fill/run fuel selector such that fuel is pumped from a storage tank external to the vehicle into a vehicle fuel tank by way of the vehicle fuel pump in the refuel mode, and fuel is pumped to an engine of the vehicle from the vehicle fuel tank by way of the vehicle fuel pump in the run mode.

A tank assembly includes a tank, at least one pressure relief valve, at least one heat transmission path, and at least one heat transmission element. The at least one pressure relief valve is configured to allow a pressure relief of the tank when a temperature threshold value at the pressure relief valve is exceeded. The heat transmission path and the pressure relief valve are connected via the at least one heat transmission element. The heat transmission element is changeable with respect to the heat transmission between the heat transmission path and the pressure relief valve.

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 high pressure container system is equipped with an upstream side pressure sensor that measures an internal pressure of high pressure containers upstream of a pressure regulating valve, a plurality of downstream side pressure sensors that measure the pressure of the fluid downstream of the pressure regulating valve, and a control device. At a normal time of the downstream side pressure sensors, a control device monitors the internal pressure of the high pressure containers on the basis of the measured values of the downstream side pressure sensors, and at an abnormal time when any one of the downstream side pressure sensors is abnormal, the control device monitors the internal pressure of the high pressure containers on the basis of the measured values of the downstream side pressure sensors, and the measured value of the upstream side pressure sensor.

An integrated fill system is provided for a vehicle. The integrated fill system can include a container configured to house a compressed gas having a first end and a second end. A first neck mount is configured to receive the first end of the container and configured to restrict movement, and a second neck mount is configured to receive the second end of the container and configured to enable movement. A housing is configured to encase the container and the first and second neck mounts. A fill line has a first end coupled to the first end of the container, and a draw line has a first end coupled to the second end of the container. A filter is arranged proximate to the fill line to prevent contaminants from entering the container.
