Abstract: Systems and methods for controlling fuelling of dual fuel internal combustion engines are disclosed. The control techniques maximize the substitution rate of gaseous fuel for the liquid fuel by determining a target fuelling amount for the liquid fuel and then regulating an actual fuelling amount of the liquid fuel in response to engine speed and power variations and by modulating the flow rate of the gaseous fuel to the engine.

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.

Abstract: The present disclosure relates to systems and methods for managing engine output. A method includes receiving at least one of a torque input and an acceleration input; generating a torque request for an engine; receiving the torque request; and determining an amount of the torque request that can be provided by a fast response actuator including a spark timing actuator based on a governed torque fraction value based on existing operating conditions of the spark timing actuator and a torque fraction value indicative of a total torque request value and an anticipated future torque demand value. The method includes managing the spark timing actuator to produce the amount of torque; determining a remaining amount of the torque request that cannot be provided the fast response actuator based on an existing operating condition of the engine; and commanding a slow response actuator to provide the remaining amount of the torque request.

Abstract: A communications system having a network of nodes that may transmit and receive wireless signals. RF channel quietness may be measured at each node. A channel that is the best for all of the nodes may be selected. However, if all of the nodes except for one node determine that a particular channel is the best and not acceptable to the one node but that another channel is acceptable to all of the nodes, then the entire network may choose to operate on the other channel. The network may choose to operate on more than one channel in a time slotted fashion if a single acceptable channel cannot be found for all of the nodes. Channel quietness measurements may be facilitated by and uploaded to a host controller. The host controller may build a profile of measurements from the nodes for each channel.
