    摘要: A diesel engine (E) has a combustion chamber (C), a piston (T) movable in the chamber, air intake and exhaust valves (IV, EV), and a nozzle (N) injecting fuel into the combustion chamber. By controlling characteristics of an air-fuel mixture, emissions produced by combustion of the air-fuel mixture in the chamber are reduced to levels which satisfy the Tier 2 requirements established by the Environmental Protection Agency (EPA) for the engine. This may include controlling hydraulic flow characteristics through the nozzle, increasing the compression ratio within the combustion chamber, lowering the manifold air temperature (MAT), and retarding the start of fuel injection (SOI) within the chamber.

    摘要: A method and system for controlling a compression ignition engine in railroad locomotives and other land or marine-based large propulsion or power generation equipment operable in a selected one of a plurality of engine throttle notches is provided. Each throttle notch is indicative of a respective load condition of the engine. The engine has an intercooling system using a predetermined cooling fluid and the engine is configured to receive a predetermined combustion-supporting fluid (e.g., air) into a plurality of cylinders through respective intake manifolds. The method allows for sensing the selected throttle notch, and for selectively actuating the intercooling system to adjust a predetermined operational parameter (e.g., intake manifold air temperature) based on the sensed throttle notch and/or environmental conditions.

    摘要: A fuel injection timing control system for diesel engines operating at high altitude, including a sensor for a parameter of the engine intake air, such as engine intake air pressure or turbocharger speed. This sensor communicates with a barometric pressure timing controller, and a throttle position sensor communicates with the barometric pressure timing controller. Nominal values of the engine intake air parameter at various throttle notch settings and various engine performance parameters are stored in a table, for a nominal barometric pressure. The barometric pressure timing controller determines the instantaneous barometric pressure by adjusting the nominal barometric pressure based on the difference between the instantaneous value for the engine intake air parameter and the nominal value for the engine intake air parameter, at the known throttle notch setting and the known engine performance parameters. The barometric pressure timing controller then adjusts fuel injection timing in response to the thusly determined barometric pressure and the sensed throttle position, by advancing or retarding the fuel injection timing by predetermined values as the barometric pressure or the throttle position changes. The predetermined values of fuel injection timing are selected to reduce exhaust emissions and increase engine efficiency and performance under various barometric pressure conditions so that the engine may be operated continually and optimally under various barometric pressure conditions.

    摘要: A common rail fuel injection apparatus (1) for a multi-bank, diesel locomotive engine (10). A common rail (20,22) is disposed proximate each bank (20,22) of cylinders (12) of the engine to provide high pressure fuel (30) to a fuel flow control apparatus (14) associated with each respective cylinder. A plurality of high-pressure fuel pumps (34) provides high-pressure fuel to at least one of the common rails. A fluid cross connection (38) is provided to convey high pressure fuel between the two common rails, thereby providing for the continued delivery of fuel to all cylinders in the event of a failure of one of the high pressure pumps. The high-pressure pumps are motivated by fuel lobes (64) located on camshaft sections (50a, 50b, 50c) adjoined at a gear driven end 58 of the camshaft (50). Camshaft sections (50d, 50e, 50f) adjoined at an idler end (60) of the camshaft carry lower torque loads than those sections having fuel lobes and may be formed from a lower strength material or may have a smaller shaft diameter.

    摘要: A method is provided including determining a first power level required from a diesel powered system. The first power level corresponds to a first proportion of a maximum power. The method also includes determining an emission output for a mission based on the first power level. The method further includes determining a second power level corresponding to a second proportion of the maximum power, wherein alternate use of the second power level and at least one of the first power level or a third power level results in a lower emission output for the mission, with the overall resulting power being proximate the minimum power required. The method also includes automatically controlling operation of the diesel powered system by using the second power level alternately with at least one of the first power level or the third power level.
