A fuel injector includes a first check valve member that seats on an injector body, and a second check valve member that seats on the first check valve member covers a first nozzle outlet set when in a closed position. When the first check valve member moves to an open position, gaseous fuel is injected through both a first nozzle outlet set and a second nozzle outlet set. When the second check valve member moves to an open position, liquid fuel moves through a through passage defined by the first check valve member to facilitate injection of the second nozzle outlet set. The first and second check valve members may be controlled by first and second control valves, respectively. |
