Abstract

The present application concerns a fuel supply system, an internal combustion engine, a propulsion system, a use of a vacuum ejector, and a method for operating an internal combustion engineThe fuel supply system (100) for supplying a fuel, in particular methanol, ammonia, LNG, or LPG, to an internal combustion engine (200), in particular having at least one cylinder (210) with a bore having a diameter of at least 200 mm, comprises a double-walled fuel pipe (10) for guiding the fuel to at least one fuel injector (1) of the large combustion engine (200). The double-walled fuel pipe (10) comprises a fuel line (12) and a fuel pipe space (11i, 11o) at least partly surrounding the fuel line (12), wherein the double-walled fuel pipe (10) comprises an outside fuel pipe section (10o) arrangeable outside of an engine room (226) hosting the at least one cylinder (210) and an inside fuel pipe section (10i) arrangeable inside of the engine room (226). The fuel supply system (100) further comprises a double-walled return pipe (13) comprising a return line (15) and a return pipe space (14i, 14o) at least partly surrounding the return line (13). The double-walled return pipe (13) comprises an outside return pipe section (13o) arrangeable outside of the engine room (226) and an inside return pipe section (13i) arrangeable inside of the engine room (226). The fuel pipe space (11i, 11o) is fluidly connected or connectable to the return pipe space (14i, 14o), and the fuel supply system (100) comprises a leakage line (20) which is fluidly connected or connectable to the fuel pipe space (11i) of the inside fuel pipe section (10i) and to the return pipe space (14i) of the inside return pipe section (13i).
