    • A diesel locomotive includes a number of auxiliary subsystems operating in conjunction with the locomotive diesel engine and deriving their energy, from the diesel engine. Included among the subsystems are various cooling systems, the battery charging system, and the electrical generation system, comprising one or more alternators drivingly coupled to the engine shaft. Each of the subsystems includes a component that is activated when one or more operational conditions associated with the subsystem are met. For instance, an engine cooling system fan motor is activated when the coolant temperature exceeds a predetermined value. Similarly, a battery charger is activated when the battery voltage falls below a predetermined value, and an alternator blower is activated when the main or auxiliary alternator temperature exceeds a predetermined value. The activation of these power consuming auxiliary devices while the diesel engine is transitioning from a first load state to a higher load state, causes the formation of excessive smoke emissions. According to the present invention, the activation of these auxiliary components is delayed until the diesel engine has reached steady-state operation, after which the elements are activated as required. Also, in the event a subsystem operational parameter exceeds a predetermined critical limit, the auxiliary device is immediately activated, even if the diesel engine is in a transition state to a higher load value.
    • 柴油机车包括与机车柴油机一起操作并从柴油发动机获得能量的多个辅助子系统。 子系统中包括各种冷却系统,电池充电系统和发电系统,包括驱动地连接到发动机轴的一个或多个交流发电机。 每个子系统包括当满足与子系统相关联的一个或多个操作条件时激活的组件。 例如,当冷却剂温度超过预定值时,发动机冷却系统风扇马达被启动。 类似地,当电池电压低于预定值时,电池充电器被激活,并且当主或辅助交流发电机温度超过预定值时,交流发电机被激活。 当柴油机从第一负载状态转换到较高负载状态时,这些功耗辅助装置的激活导致形成过多的烟雾排放。 根据本发明,这些辅助部件的启动被延迟,直到柴油发动机达到稳态运转为止,然后根据需要激活元件。 此外,在子系统操作参数超过预定的临界极限的情况下,即使柴油发动机处于过渡状态到更高的负载值,也立即启动辅助装置。
