  "textContent": "A fuel injector (10) configured to inject a predetermined volume of fuel, such as heavy fuel oil, is disclosed. The disclosed injector (10) includes an injector body (11) that defines a fuel inlet (19), a fuel passageway (21), and an orifice (25). The injector (10) also includes a needle (23) disclosed at least partially within the injector body (11). The needle (23) is movable between a closed position where the needle (23) blocks the orifice (25) and an open position where the needle (23) at least partially unblocks the orifice (25). At least the injector body (11) and the needle (23) define a nozzle chamber (22). The nozzle chamber (22) is in communication with a high pressure fuel passageway (21) and the orifice (25). The fuel passageway (21) and nozzle chamber (22) have a combined volume greater than the predetermined injection volume. The combined volume of the nozzle chamber (22) and fuel passageway (21) act as a damper to alleviate the effects of pressure overshoot, pressure oscillations and water hammer.",
