Abstract: A control system for an engine is disclosed. The control system may have a first gaseous-fuel injector configured to inject gaseous fuel into a first intake passage associated with at least a first cylinder and a second gaseous-fuel injector configured to inject gaseous fuel into a second intake passage associated with at least a second cylinder. The control system may also have a variable orifice disposed within the second intake passage upstream of the first gaseous fuel injector. The control system may additionally have a sensor configured to provide a signal indicative of a performance parameter of the engine and a controller 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.
