Abstract: A liquid fuel injector such as for a dual fuel system in an internal combustion engine includes two-way injection control valves for controlling twin outlet checks. A first set of orifices are arranged in an A-F-Z pattern, and a second set of orifices are arranged in an A-F-Z pattern, within the fuel injector, among a high-pressure inlet passage, a low-pressure space, and first and second outlet check control chambers, respectively. A common nozzle supply cavity is fluidly connected to the high-pressure inlet passage and supplies each of two sets of nozzle outlets opened and closed by the twin outlet checks.
