Abstract
The invention relates to a common rail fuel injectionsystem(1) for a piston engine with several cylinders (12). The fuel injection system (1) comprises at least one pressure accumulator (7, 8, 18) for pressurized fuel, injectors (6) for injecting pressurized fuel into the cylinders (12) and a leakage channel arrangement (24) for removing fuel leaking from the injectors (6). The leakage channel arrangement (24) is provided with a leak detector (28) for detecting a fuel leak.
