A system for controlling a hybrid propulsion system includes a computer programmed to obtain altitude and terrain information associated with a predetermined route for the hybrid propulsion system comprising a first energy source and a second energy source. The computer is also programmed to obtain current and forecast ambient weather information associated with the predetermined route of the hybrid propulsion system, determine a power requirement and a torque requirement of the hybrid propulsion system associated with the altitude and the terrain along the predetermined route of the hybrid propulsion system, generate a trip plan to optimize at least one of a plurality of performance parameters of the hybrid propulsion system as the hybrid propulsion system travels along the predetermined route, and preferentially select the first energy source and/or the second energy source based on the trip plan.

Hybrid propulsion system and method of controlling same

A turbine-compressor assembly includes a turbine-compressor device fluidly coupled with a heat source, a compressor, and a turbine via plural valves. A power device is coupled with the turbine-compressor device via a shaft. A controller can control operation of the plural valves to control the movement of fluids within the assembly to selectively switch between the turbine-compressor device operating in one of plural operating modes. In a first mode of operation, the turbine-compressor device can generate electrical power and direct the electrical power to the power device to control an amount of power provided to or extracted from the shaft by the power device. In a second mode of operation, the turbine-compressor device can receive electrical power from the power device to consumer the electrical power.

Turbine-compressor assembly and method

Various methods and systems are provided for generating exhaust energy and converting exhaust energy to electrical energy while an engine is not running. In one example, a system for an engine comprises: a first turbocharger including a first compressor driven by a first turbine, the first turbine disposed in an exhaust of the engine; a fuel burner fluidly coupled to the exhaust upstream of the first turbine; a generator coupled to one of the first turbine or an auxiliary, second turbine fluidly coupled to the exhaust downstream of the fuel burner; and one or more bypass valves configured to adjust a flow of air that bypasses the engine and is delivered to the fuel burner.

Method and systems for an energy recovery and energy converting unit for an engine

Various methods and systems are provided for controlling air flow through an engine by adjusting an electric turbocharger of a vehicle. In one embodiment, a system for a vehicle comprises an electric turbocharger comprising a compressor, an exhaust turbine coupled to the compressor via a shaft, and an electric machine mechanically coupled to the shaft; and a controller including a processor and instructions stored on a non-transient memory of the controller that, when executed, cause the controller to: adjust an amount of power provided to or extracted from the shaft by the electric machine based on at least one of a speed of the electric turbocharger, a cylinder pressure, and an exhaust gas temperature. By adjusting the amount of power provided to or extracted from the electric machine, the exhaust gas temperature and the speed of the electric turbocharger may be efficiently maintained within a desired operating range.

Methods and systems for electric turbocharger control

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 (e.g., air) from outside the body and to receive one or more streams of fuel from the fuel injector in the interior volume. The body also includes one or more upper channels and one or more lower channels that are configured to provide a substantially similar amount of flow relative to each other to 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.

Engine mixing structures

A piston crown for a combustion system is disclosed. The piston crown includes a piston bowl having a circumferential recess and a plurality of first recesses arranged spaced apart from each other along a circumferential direction. The circumferential recess is disposed proximate to a circumference of the piston crown. Each recess of the plurality of the first recesses extends between a center of the piston crown and the circumferential recess, and a width and a depth of each recess of the plurality of first recesses are extended along a radial direction for an entire length of each recess of the plurality of first recesses.

Piston crown for a combustion system and an associated method thereof

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.

Oil carryover reduction system

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.

Vehicle control system

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.

Various methods and systems are provided for skip-firing an engine. As one embodiment, a method for an engine includes firing all cylinders of the engine and not altering the closing timing of the intake valves when fueling demands are greater than a threshold. The method further includes skip-firing the engine when fueling demands are less than a threshold, and holding open the intake valves of skipped cylinders for a greater duration than intake valves of firing cylinders.
