摘要： A railroad locomotive includes a naturally-aspirated reciprocating internal combustion engine, and a traction generator driven by the engine. A throttle position sensor produces a signal corresponding to the throttle position selected by the locomotive's operator. A load regulator receives a speed signal derived from the throttle position signal and outputs an excitation signal for the traction generator which is modified by a controller in response to air availability so that engine speed and load are controlled independently of the selected throttle position, so as to limit the exhaust smoke output of the engine.

摘要： An improved high viscosity fuel injection pressure reduction system and method is disclosed for use in an internal combustion engine. The system may include a first fuel line and a second fuel line. The first fuel line may be configured to be coupled upstream of a combustion chamber of the engine when the engine is operated with the first fuel and to provide a first pressurized volume when installed. Likewise, the second fuel line may be configured to be coupled upstream of the combustion chamber of the engine when the engine is operated with the second fuel and to provide a second pressurized volume when installed. The first and second volumes of the fuel lines may provide peak injection pressures lower than a desired pressure when the engine is operated with the first and second fuels, respectively.

摘要： Pumps and injectors utilize a control valve having a valve body with a valve stem having a step adjacent to the seating surface. The step extends a limited distance away from the seating surface to provide limited pressure relief when the valve body is at an intermediate position that is between the opened and closed positions. Step cross-section and axial length may be configured based on desired hydraulic behavior. In a preferred embodiment, the control valve step is configured for injection rate shaping.
