Embodiment Construction
[0020] figure 1 A liquefied gas fuel feed system 10 is schematically shown, suitable for feeding a gaseous fuel to an internal combustion piston engine 12 , for example in a land-based or marine power plant. A liquefied gas fuel feed system 10 for an internal combustion piston engine 12 includes a reservoir 14 . The reservoir 14 is configured to store fuel at low temperatures, which means that it is provided with suitable thermal insulation. Likewise, the reservoir is configured to store fuel which is typically only at moderate pressure (eg, about 100 kPa to 400 kPa, or at least below 1 MPa). Thus, in use, ie when filled with gas, the reservoir (more precisely the inner space of the reservoir) comprises a liquefied gas space 14.1 with a surface 14.2 and an empty space 14.3 above this surface.
[0021] The gaseous fuel feed system 10 also includes a fuel supply line 16 . The fuel supply line 16 is arranged to extend from the reservoir 14 to the internal combustion piston eng...
