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

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.
