A gas tank arrangement for an internal combustion engine, the gas tank arrangement comprising a gas tank for containing a combustible gas, a first fuel pump arranged downstream the gas tank and arranged to increase the pressure level of the combustible gas to a first pressure level, wherein the gas tank arrangement further comprises a second fuel pump arranged downstream the first fuel pump and arranged to increase the pressure level of the combustible gas to a second pressure level, wherein the second pressure level is higher than the first pressure level.

Gas tank arrangement

The present invention relates to a gas tank arrangement () for an internal combustion engine (), said gas tank arrangement () comprising a gas tank () for containing a combustible gas, a first fuel pump () arranged downstream said gas tank () and arranged to increase the pressure level of the combustible gas to a first pressure level, wherein the gas tank arrangement () further comprises a second fuel pump () arranged downstream the first fuel pump () and arranged to increase the pressure level of the combustible gas to a second pressure level, wherein said second pressure level is higher than said first pressure level.

A gas tank arrangement for an internal combustion engine is provided, the gas tank arrangement including a gas tank configured to contain a combustible gas, and a first additional gas tank positioned in downstream fluid communication with the gas tank, wherein the gas tank arrangement further includes a second additional gas tank positioned in downstream fluid communication with the gas tank and in upstream fluid communication with the first additional gas tank. A vehicle including such a gas tank arrangement is also provided.

A fuel tank arrangement for a dual fuel internal combustion engine includes a fuel tank arranged to supply liquid fuel to the dual fuel internal combustion engine, wherein the fuel tank arrangement includes a return conduit connected to the fuel tank and configured to supply leaked fuel from the dual fuel internal combustion engine to the fuel tank, wherein the fuel tank arrangement includes a first fuel separation arrangement positioned in fluid communication between the fuel tank and an outlet to an ambient environment thereof.

A safety arrangement for a DME fuel tank of a vehicle, adapted to release an excessive pressure from the fuel tank, including a spring-loaded pressure release valve adapted to open at a predefined pressure level, where the safety arrangement further includes a housing mounted on the fuel tank and having an outer opening closed by a lid, where the pressure release valve is arranged in the housing and where the housing is provided with an outlet pipe having an outlet opening, and where the lid is adapted to melt at a predefined temperature, thereby allowing gas to exit the pressure release valve through the outer opening of the housing when the pressure release valve is open and the lid has melted. A small gas leakage caused by an excessive pressure can be discharged downwards through the outlet pipe and outlet opening towards the ground, and a large gas leakage, caused by e.g. a fire, can be discharged outwards from the fuel tank, away from the fire.

Safety arrangement for a vehicle tank

A filter device, particularly an air breather filter device for venting a fuel tank, includes a housing with a first port provided as an inlet in normal operation of the filter device and a second port provided as an outlet under normal operation of the filter device. The housing encloses at least one filter and an air passage extends from the first port to the second port passing through the filter. Inside the housing a baffle unit is arranged in the housing for covering the at least one first filter in relation to the second port, wherein the baffle unit is arranged to deflect a fluid flow entering the filter device through the second port.

Filter device and arrangement for ventilating a tank comprising a filter device

A tank arrangement for a vehicle, particularly a truck, includes at least a first fuel tank and a second fuel tank which are connected by a balancing pipe, a suction pipe for feeding fuel to an engine and a return pipe for feeding fuel from the engine to at least one of the fuel tanks. The balancing pipe is provided with a first end to supply fuel to the first tank and a second end to suck fuel from the second tan, wherein a check valve is arranged upstream of the return pipe in the balancing pipe between the at least two tanks allowing a flow direction from the second tank to the first tank and blocking a flow in the reverse direction. Suction of fuel to the engine is from the first tank only. The check valve provides an automatic purging of the system.

Tank arrangement and vehicle with a tank arrangement

Cabling for a motor vehicle includes at least one fluid hose, a first cable for heating the fluid hose and at least one electrical connector for connecting the cable to an electrical supply, and at least one hose connector for connecting the fluid hose to a cooperating connector means. The hose connector may be provided with an electrically heated device arranged to heat at least part of the hose connector.

Heated coupling

A device for heating a first medium which is in liquid state and/or frozen state includes a reservoir disposed on an engine-driven vehicle and an element for heating the first medium present in the reservoir. The heating element is disposed inside the reservoir for direct heating of the first medium.
