Abstract: A traction loss warning system includes a warning controller configured to be disposed onboard a first vehicle and to determine a location on a route where a loss in traction of the first vehicle occurred and a vehicle controller configured to be disposed onboard a second vehicle, the vehicle controller configured to control movement of the second vehicle along the route. The warning controller also is configured to communicate a warning signal that notifies the second vehicle of the location where the loss in traction of the first vehicle occurred. The vehicle controller is configured to change the movement of second vehicle along the route during travel of the second vehicle over the location responsive to receiving the warning signal from the warning controller.

Abstract: A control system includes a communication device onboard a vehicle system approaching or entering an airflow restricted area along a route and one or more processors. The communication device configured to receive status messages that contain data parameters representative of ambient conditions within the airflow restricted area. The processors are configured to monitor the ambient conditions and determine different power output upper limits that a trail propulsion vehicle of the vehicle system can generate within the airflow restricted area based on the ambient conditions and different power outputs generated by a lead propulsion vehicle of the vehicle system. The processors further configured to communicate instructions to control the lead propulsion vehicle within the airflow restricted area to generate the power output of the different power outputs that results in the greatest total available power output of the vehicle system as the vehicle system travels within the airflow restricted area.

The rotating detonation combustor is configured for a rotating detonation process to occur within the at least one combustion chamber to generate a combustion flow including a first portion and a second portion. The turbine engine also includes a turbine coupled in flow communication with the rotating detonation combustor. The turbine is configured to receive the combustion flow from the rotating detonation combustor. The turbine includes a first blade and a second blade that rotate about an axis at a rotational frequency. The rotating detonation combustor and the turbine are configured for the combustion flow first portion to contact the first blade substantially continuously as the first blade rotates.

Abstract: A method includes controlling an engine speed based on: intake manifold air temperature and/or intake manifold pressure one, or more, of the following data parameters: an engine load as a function of a fuel level, a fuel injecting timing, an intake oxygen concentration, a constituent concentration from the exhaust gas flow, an engine power, and an engine torque. The method also recirculates a portion of the exhaust gas flow to the combustion cylinders of the engine via a recirculation channel, as a function of intake manifold temperature and/or intake manifold pressure at which the engine is operated. An engine system, other methods, and a non-transitory computer readable medium encoded with a program, to enable a processor-based control unit to control aspects of the engine are also disclosed.

Abstract: A system includes one or more processors configured to be operably coupled to a vehicle system configured to travel along a route during a trip. The vehicle system has a vehicle particulate filter (VPF) disposed within an exhaust passage of the vehicle system. The one or more processors are configured to determine, based on trip information about the trip of the vehicle system, one or more regeneration-incompatible (RI) portions of the trip. The RI portions are associated with operating conditions of the vehicle system that are unsuitable for contemporaneous active regeneration of the VPF. The one or more processors are further configured to schedule an active regeneration (AR) event for the vehicle system based on the one or more RI portions of the trip. The AR event occurs during a regeneration portion of the trip.

Abstract: Various methods and systems are provided for a multi-fuel capable engine. In one example, a system comprises an engine having at least one cylinder controlled via an intake valve, a first fuel system to deliver liquid fuel and a second fuel system to deliver gaseous fuel to the at least one cylinder, a variable valve timing actuation system to adjust one or more of an opening or a closing timing of the intake valve, and a controller. The controller is configured to, during a liquid fuel only mode, adjust the variable valve timing actuation system to close the intake valve at a first timing based at least on engine load, and during a multi-fuel mode, adjust the variable valve timing actuation system to close the intake valve at a second timing.
