METHOD OF FILLING A FUEL TANK WITH LIQUEFIED GAS AND LIQUEFIED GAS FUEL SYSTEM

摘要

The invention relates method of filling a fuel tank (12) with liquefied gas, in which method liquefied gas is brought into the tank so that gas in introduced to a lower section (12.1) of the tank below the surface of the liquefied gas in the tank, and during a first phase of the filling procedure while gas in introduced to a lower section of the tank the pressure of the tank is maintained below a predetermined set pressure by spraying of liquefied gas into a gas space in the upper section (12.2) of the tank above the surface of the liquefied gas in the tank. In the method at a predetermined state of the filling procedure a second phase of the procedure is initiated during which the spraying liquefied gas into a gas space in the upper section (12.2) of the tank is decreased and the second phase is practised until a predetermined filling stage of the tank is reached to fuel (14.1).
