Abstract
A method for starting gas delivery from a liquefied gas fuel system includes a fuel tank filled with liquefied gas by a filling procedure and the filling procedure resulting in the pressure in the tank being at least at an operational pressure required by the engine. The method pressure in the tank is controlled by controlling the operation of a pressure build up system including the pressure build up evaporator which is arranged in a conduit leading from the bottom section of the tank to the upper section of the tank. The pressure build up system is controlled by controlling the flow rate of the evaporated gas in the conduit while the heat transfer medium is allowed to flow unconstrained through the pressure build up evaporator.
