用于柴油发动机的集成发动机控制和冷却系统
摘要：
一种机车包括发动机(12)、中间冷却器(16)和油冷却器(28)，所述发动机、中间冷却器和油冷却器的每个具有形成在其中的相应冷却通道。该机车也包括与相应冷却通道选择性连通的冷却系统(10)，从而选择性地将第一冷却剂(56)和温度高于第一冷却剂的第二冷却剂(52)供给至冷却通道。一种操作冷却系统的方法，包括在第一模式下将第一冷却剂流(26)供给至中间冷却器，将处于不同于第一冷却剂流的第一温度的第二冷却剂流(30)供给至油冷却器，从而实现中间冷却器的优选冷却。该方法也包括在第二模式下将第一冷却剂流供给至中间冷却器，将处于不同于第一冷却剂流的第二温度的第二冷却剂流供给至油冷却器，从而实现油冷却器的优选冷却。
摘要（英）：

A locomotive includes an engine (12), an intercooler (16), and an oil cooler (28), each having respective cooling passages formed therein. The locomotive also includes a cooling system (10) in selective communication with the respective cooling passages for selectively providing a first coolant (56) and a second coolant (52) at a higher temperature than the first coolant to the cooling passages. A method of operating the cooling system includes providing, in a first mode, a first coolant flow (26) to the intercooler and a second coolant flow (30) to the oil cooler at a first temperature different than the first coolant flow to achieve preferential cooling of the intercooler. The method also includes providing, in a second mode, the first coolant flow to the intercooler and the second coolant flow to the oil cooler at a second temperature different than the first coolant flow to achieve preferential cooling of the oil cooler.
