Abstract:
One exemplary embodiment is a system comprising a dual-fuel engine structured to selectably combust a first fuel type and a second fuel type, and an electronic control system in operative communication with the dual-fuel engine. The electronic control system is structured to control a transition of the dual-fuel engine from a dual-fuel mode to a single-fuel mode. After initiating the transition from the dual-fuel mode to the single-fuel mode, the control system stops provision of the second fuel type, requires combustion using control parameters configured for the dual-fuel mode until a transition ventilation condition is satisfied, permits non-emergency commanded engine shutdown only if the transition ventilation condition is satisfied.
