Abstract: A system includes a conversion circuit of a vehicle system that conductively couples a conversion device with first motors of the vehicle system. The electrical conversion device converts non-electrical energy into conversion-based electric current that is conducted to the first motors. The system also includes a storage circuit of the vehicle system that conductively couples a storage device with second motors of the vehicle system. The storage device supplies stored electric current to the second motors of the vehicle system. The system also includes a controller configured to control the second motors to brake and generate charging electric current that is conducted through the storage circuit to charge the storage device. The conversion circuit and the storage circuit are separate circuits such that the storage device is not charged with the conversion-based electric current conducted in the conversion circuit.

Abstract: Fuel injector wear methodologies for use with internal combustion engines include a method that determines power of the engine and/or fuel flow of a fuel injector(s) associated with a cylinder the engine; obtains a duration of a fuel injection event from the injector(s) associated with the cylinder(s) of the engine; compares the power, the fuel flow, and/or the duration with a reference value; and then adjusts the fuel injection timing of the fuel injector(s), based on the comparison. Another method adjusts operation of an engine includes: comparing two (or more) engine models, wherein one model is related to a fuel injection event duration of the engine or a modeled fuel quantity being supplied to the engine and then adjusting the fuel injection timing of a fuel injector(s) of the engine, based on the comparison.

Abstract: A system includes an engine coupled with a primary shaft that drives a first electric generator for generating electrical power via a gear subsystem. The system also includes a turbocharger assembly having at least one gas turbine engine configured for driving the primary shaft and coupled in parallel with the engine. The turbocharger assembly includes multiple compressors configured to provide a flow of compressed fluid into both the engine and the at least one gas turbine engine and multiple turbines configured to utilize exhausts from both the engine and the one gas turbine for driving the primary shaft. Further, the system includes a controller configured to operate a plurality of valves for controlling optimal intake fluid pressure into the engine and the turbocharger assembly and fuel injections into the engine and the at least one gas turbine engine.

Abstract: A system in one embodiment includes at least one cylinder, a supplemental boost supply, and a supply line. The at least one cylinder is configured for use in a reciprocating internal combustion engine, and includes a combustion portion and a crank portion on opposite sides of a piston. The at least one cylinder also includes an intake port and an exhaust port in fluid communication with the combustion portion. The supplemental boost supply is configured to provide a supplemental air supply to the combustion portion of the engine when the engine is idling to increase pressure in the combustion portion. The supply line couples the supplemental boost supply to the intake port.
