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 cool...

| 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. |
