Integrated engine control and cooling system for diesel engines
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)...

| description | 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. |
