A gas supply system includes: high-pressure tanks having at least different longitudinal lengths; supply pipes each connected to corresponding one of the high-pressure tanks; a supply-side manifold to which the supply pipes are connected; solenoid valves disposed in the respective supply pipes; a first pressure sensor configured to acquire a pressure related to an internal pressure of the high-pressure tanks; a second pressure sensor configured to acquire a pressure at the supply-side manifold; and a control device that controls the solenoid valve corresponding to the high-pressure tank, among the high-pressure tanks, having the largest ratio of the longitudinal length to a short-side width, to open first when a value obtained by subtracting the pressure detected by the second pressure sensor from the pressure detected by the first pressure sensor is larger than a threshold at the time of activation of the gas supply system.

The present disclosure relates to a gas consumer system for a vehicle, the gas consumer system being configured to generate power by consuming gas, the gas consumer system comprising a gas consumer comprising an inlet configured to receive a flow of gas, at least one gas tank, the gas tank comprising a gas tank outlet, a conduit connecting the gas tank outlet of the tank to the inlet of the gas consumer, and an elongated sleeve attached to the inlet of the gas consumer and to the gas tank outlet of the gas tank, wherein the conduit is housed within the elongated sleeve, the elongated sleeve comprising a sleeve outlet configured to convey leakage of gas between the gas consumer and the gas tank away from the gas consumer system.

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.

Systems are provided for an assembly for a urea tank system. In one example, coaxial tubes including an inner tube and an outer tube are used to separate a urea passage from a gas passage. An angled tube, which extends from a urea tank to a portion of the outer tube downstream of a filler head relative to a direction of urea flow directs gases from the urea tank to the gas passage. This decreases a packaging size of the urea tank system.

A vehicle includes a prime mover and a fuel system. The fuel system includes a tank, a regulator, a first shutoff valve, and a second shutoff valve. The tank is configured to provide a supply flow of fuel. The regulator is controllable to provide a regulated flow of fuel to the prime mover by modulating the supply flow of fuel. The first shutoff valve is positioned to facilitate selectively disengaging the prime mover from the fuel system. The second shutoff valve is positioned to facilitate selectively blocking the supply flow of fuel provided by the tank.

A hydrogen storage system includes: a first hydrogen tank provided in a fuel cell electric vehicle; a second hydrogen tank provided in the fuel cell electric vehicle and configured to store hydrogen independently of the first hydrogen tank; a manifold provided in the fuel cell electric vehicle and connected to the first hydrogen tank and the second hydrogen tank; a hydrogen supply line configured to connect the manifold and a fuel cell stack provided in the fuel cell electric vehicle; and a flow rate adjusting valve configured to adjust a flow rate of the hydrogen to be supplied to the manifold from at least one of the first hydrogen tank or the second hydrogen tank in accordance with a difference in pressure between the first hydrogen tank and the second hydrogen tank, so as to minimize a difference in pressure between the hydrogen tanks to improve safety and reliability.

A vehicle includes an engine, a tank configured to provide a supply flow of natural gas, a valve controllable to provide a regulated flow of natural gas to the engine by modulating the supply flow of natural gas, a first conduit extending between the tank and the valve such that the supply flow of natural gas is received by the valve from the tank, and a second conduit extending between the valve and the engine such that the regulated flow of natural gas is provided from the valve to the engine. The regulated flow of natural gas is not diverted from the second conduit at any point along a length of the second conduit.

The invention relates to a gas venting pipe (10) for a vehicle (100) having a forward tiltable cab, which gas venting pipe comprises: a first pipe section (12) mountable to a chassis of the vehicle; a second pipe section (14) mountable to a rear wall of the forward tiltable cab of the vehicle; and a flexible magnet connection (16) adapted to releasably interconnect the first and second pipe sections. The present invention also relates to a liquefied gas driven vehicle (100) comprising a gas venting pipe, and to a method of venting gas from a liquefied gas driven vehicle.

A combination vehicle includes a tractor and a trailer towed by the tractor. The trailer includes a first tank that is configured to store a high-pressure gas as a fuel used by the tractor to travel. The tractor includes a second tank that is configured to store a high-pressure gas as a fuel used by the tractor to travel. The combination vehicle is configured to travel using the fuel supplied from the first tank and the second tank.

A gas supply system includes: high-pressure tanks having at least different longitudinal lengths; supply pipes each connected to corresponding one of the high-pressure tanks; a supply-side manifold to which the supply pipes are connected; solenoid valves disposed in the respective supply pipes; a first pressure sensor configured to acquire a pressure related to an internal pressure of the high-pressure tanks; a second pressure sensor configured to acquire a pressure at the supply-side manifold; and a control device that controls the solenoid valve corresponding to the high-pressure tank, among the high-pressure tanks, having the largest ratio of the longitudinal length to a short-side width, to open first when a value obtained by subtracting the pressure detected by the second pressure sensor from the pressure detected by the first pressure sensor is larger than a threshold at the time of activation of the gas supply system.
