Abstract

In an arrangement for locating fuel leak in connection with a large combustion engine (5), particularly a large diesel engine, fuel is fed into several fuel injectors (8) from a common fuel space (9, 10), and a fuel injection system comprises a double wall (15) fuel pipe system (11, 12, 3), which in turn comprises an inner flow space (14) for fuel and outer flow space (16) for possibly leaking fuel. The fuel injection system comprises at least one leaking fuel detection arrangement (18, 18', 18", 18"') in connection with an outer flow channel (16) of at least one section of the pipe system (11, 12, 13). <IMAGE>
