  "textContent": "A fuel injector in a dual fuel system forms a first nozzle supply passage for a first fuel, a multi-channel nozzle supply path for a second fuel, and a combined-fuel outlet passage. The fuel injector further forms a valve seat and a check control chamber, and includes a control valve movable between a first position and an open position, to control a hydraulic pressure of the second fuel in the check control chamber. The fuel injector further includes a nozzle check movable from a closed position blocking the plurality of nozzle outlets from the combined-fuel outlet passage, to an open position to inject a combined fuel charge containing both the first fuel and the second fuel. The multi-channel nozzle supply passage provides flow area especially for operating the dual fuel system in a diesel-only mode. e",
