Beschreibung
Zusammenfassung:	A control system (18) for an engine (12) is disclosed. The control system may have a first gaseous-fuel injector (36) configured to inject gaseous fuel into a first intake passage (30) associated with at least a first cylinder (22) and a second gaseous-fuel injector (38) configured to inject gaseous fuel into a second intake passage (32) associated with at least a second cylinder (22). The control system may also have a variable orifice (70) disposed within the second intake passage upstream of the first gaseous fuel injector. The control system may additionally have a sensor (72) configured to provide a signal indicative of a performance parameter of the engine and a controller (68) electronically connected to the variable orifice and the sensor. The controller may be configured to move the variable orifice to adjust a ratio of air-to-fuel in the first and second intake passages based on the signal.
