Abstract
A system is provided that includes a controller configured to determine one or more propulsion-generating vehicles in a group of propulsion-generating vehicles that have an increased risk for damage to an engine system based on operation at a fueling level that is less than a designated threshold fueling level for at least a designated time period. The controller is further configured to determine respective power outputs for the propulsion-generating vehicles in the group such that the one or more propulsion-generating vehicles having the increased risk for damage to the engine system do not operate below the designated threshold fueling level for longer than the designated time period.
Claims20
A system comprising:
- a controller configured to determine one or more propulsion-generating vehicles in a group of propulsion-generating vehicles that have an increased risk for damage to an engine system based on operation at a fueling level that is less than a designated threshold fueling level for at least a designated time period, wherein during the designated time period the one or more propulsion-generating vehicles in the group that have an increased risk for damage to the engine system can operate below the designated threshold fueling level without at least a designated amount of oil being present in exhaust emitted by the one or more propulsion-generating vehicles, and
- the controller is further configured to determine respective power outputs for the propulsion-generating vehicles in the group such that the one or more propulsion-generating vehicles having the increased risk for damage to the engine system do not operate below the designated threshold fueling level for longer than the designated time period.
A method comprising:
- determining one or more propulsion-generating vehicles in a group of propulsion-generating vehicles that have an increased risk for damage to an engine system based on operation at a fueling level that is less than a designated threshold fueling level for at least a designated time period, wherein during the designated time period the one or more propulsion-generating vehicles in the group that have an increased risk for damage to the engine system can operate below the designated threshold fueling level without at least a designated amount of oil being present in exhaust emitted by the one or more propulsion-generating vehicles;
- and
- determining respective power outputs for the propulsion-generating vehicles in the group such that the one or more propulsion-generating vehicles having the increased risk for damage to the engine system do not operate below the designated threshold fueling level for longer than the designated time period.
A system comprising:
- a controller configured to determine if a propulsion-generating vehicle has a risk for damage to an exhaust-based system of that vehicle based at least in part on operation of the vehicle at a fueling level that is less than a designated threshold fueling level for at least a designated time period, the exhaust-based system configured to receive exhaust from an engine of the respective propulsion-generating vehicle, wherein during the designated time period the one or more propulsion-generating vehicles in the group that have an increased risk for damage to the engine system can operate below the designated threshold fueling level without at least a designated amount of oil being present in the exhaust from the engine and the risk of damage to the exhaust-based system increases over time;
- and
- the controller is further configured to determine a respective power output for the propulsion-generating vehicle so that the propulsion-generating vehicle does not operate below the designated threshold fueling level for longer than the designated time period.
