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, and an additional gas tank () arranged in upstream fluid communication with said internal combustion engine (), wherein the gas tank arrangement () further comprises a valve arrangement () positioned in fluid communication with the internal combustion engine (), wherein the valve arrangement () is further arranged in upstream fluid communication with the gas tank () and the additional gas tank () for controllably direct combustible gas from the internal combustion engine () to either the gas tank () or the additional gas tank ().

Gas tank arrangement

A fuel system for an internal combustion engine includes a liquefied gas tank that stores liquefied gas and a pressurized gas production unit connected to the liquefied gas tank to produce pressurized gas from the liquefied gas. A fuel rail is connected to the pressurized gas production unit. The fuel rail receives the pressurized gas and delivers the pressurized gas to a fuel injector that injects the pressurized gas into a cylinder of the engine. The pressurized gas production unit receives the liquefied gas via a mixing unit that is provided between the liquefied gas tank and the pressurized gas production unit. The mixing unit receives excess gas in the form of vaporized gas from the liquefied gas tank and/or pressurized gas from the fuel rail and mixes the excess gas with the liquefied gas received from the liquefied gas tank.

Fuel system for an internal combustion engine

A gas tank arrangement for a dual fuel internal combustion engine includes gas tank for containing a combustible gas, wherein the gas tank arrangement further includes an additional gas tank downstream the gas tank, wherein the additional gas tank is configured to be arranged in upstream fluid communication with an air inlet of the dual fuel internal combustion engine for delivery of combustible gas to the dual fuel internal combustion engine via the air inlet.

Gas tank arrangement for a dual fuel internal combustion engine

Method and arrangement for providing an underrun protection arrangement for a vehicle ( ) having a frame ( ), an impact element ( ) arranged in a position that corresponds to an anticipated stress from a force, F, in the event of a possible collision with another vehicle ( ). At least one link element ( ) is also included that is firmly connected to the impact element ( ) and is fixed so that it can pivot in relation to the said frame ( ). An energy-absorbing element ( ) is provided that connects the impact element ( ) to the frame ( ) and which is designed to compress in the event of a pivoting movement on the part of the impact element ( ). At least one locking element ( ) is included that is designed to permit the pivoting movement only in the event of a stress acting on the impact element ( ) with a force that exceeds a predetermined limit.

Arrangement for underrun protection in vehicles

Apparatus is dislosed for protecting vehicles including a crossbeam and a console mounting the crossbeam to the frame of the vehicle at a location which corresponds to the expected point of impact of a force generated by a collision, the console including an upper portion connected to the frame and comprising a hardened portion thereof, a lower portion comprising a non-hardened portion of the console, and a boundary area between these upper and lower portions comprising a weakened area of the console whereby upon impact the console is adapted to pivot about the weakened area for deformation of the console thereabout.
