Abstract: Systems and methods for controlling operation of dual fuel internal combustion engines in response to a load shedding event are disclosed. The control techniques mitigate the amount of uncombusted gaseous fuel passing into the exhaust and/or aftertreatment system and reduce the rate at which uncombusted gaseous fuel enters the cylinders to reduce engine torque output and/or speed in response to the load shedding event.
