FIELD: engines and pumps.
SUBSTANCE: invention can be used in internal combustion engines (ICE) fuel injection systems. Disclosed is a fuel system comprising fuel tank 200, configured to store a liquid fuel and a pressurised gaseous fuel capable of partially dissolving in the liquid fuel, buffer tank 270 and a refueling conduit 260. In the disclosed system, fuel from the buffer tank can be pumped to the fuel tank by means of pump 285 if it is necessary to refuel the fuel tank at the pressure and fuel level in the fuel tank below threshold levels and the fuel level in the buffer tank above the threshold level.
EFFECT: fuel or a pre-compressed mixture of fuels can be added to the fuel tank from the buffer tank at any time when the pressure in the fuel tank and the fuel level in the fuel tank are below the threshold values.
