Abstract: A computer-implemented method for multi-mode operation of a combustion system, a combustion system, and a heat engine are provided. The method includes initializing combustion of a fuel/oxidizer mixture, determining whether conditions at the combustion system meet or exceed a first threshold operating parameter, transitioning to detonation combustion of the fuel/oxidizer mixture if conditions at the combustion system meet or exceed the first threshold operating parameter, and maintaining or increasing fuel flow through a deflagrative fuel circuit if conditions at the combustion system do not meet or exceed the first threshold operating parameter.

Abstract: A vehicle control system examines characteristics of an upcoming segment of a trip of a hybrid vehicle. One or more locations in the upcoming segment of the trip are identified based on the characteristics as places where an engine of the vehicle is incapable of generating enough energy to power the vehicle through the locations. Operational settings of the vehicle are calculated based on the locations to operate the vehicle in a way that charges an energy storage device with energy that can be used to replace or supplement the energy provided by the engine to propel the hybrid vehicle over or through the locations. The one or more processors are configured to one or more of automatically control or generate a control signal for automated operation of the hybrid vehicle according to the one or more operational settings that are calculated.

Abstract: A fuel and gas mixing structure for an engine is provided. This mixing structure includes a body configured to be positioned between a fuel injector and a cylinder of an engine. The body defines an interior volume that is configured to receive gas from outside the body and to receive one or more streams of fuel from the fuel injector in the interior volume. The body also defines one or more mixture conduits configured to conduct plumes of the fuel and gas, while mixing, from the interior volume to one or more exit ports and therethrough to the cylinder.

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: 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.

Abstract: A controller for controlling emission of an internal combustion engine, that is configured to: determine an aging parameter(s) of the engine over a period of time; control an operating parameter(s) of the engine, based on the aging parameter(s); and then maintain emissions from the engine at a substantially constant value, based on the controlling. Also method of controlling emissions of an engine comprises: over a time period, determining a change in operating hours of the engine; emissions of the engine; and/or quantity of a fuel being dispensed by a fuel nozzle; controlling an operating parameter(s) of the engine during the time period, based on the determining, thereby maintaining the emissions of the engine substantially at a constant level during the same time period. A system and non-transitory computer readable media for controlling emissions of an engine are also disclosed.

Abstract: Various methods and systems are provided for adjusting an air-fuel ratio for combustion in an engine. In one embodiment, a method for an engine (e.g., a method for controlling an engine system) comprises responding to a sensed change in a load on the engine, or indications of engine knock or misfire, by one or more of: altering a speed of the engine, adjusting a fueling flow rate into at least one cylinder of the engine, and adjusting a position of a valve in a bypass passage configured to direct compressed intake air away from cylinders of the engine to obtain a determined air-fuel ratio; and thereby maintaining an air-fuel ratio in a determined range.
