SYSTEM, METHOD, AND COMPUTER READABLE MEDIA FOR CONTROLLING COOLING IN A DIESEL FUELED POWER GENERATION UNIT
First Claim
1. A cooling system for a diesel powered system having at least one diesel-fueled power generation unit, an intercooler for cooling power generation unit intake air, and main oil cooler for cooling power generation unit lubrication oil, each having respective cooling passages formed therein, and a main coolant source for providing a first coolant flow to the cooling passages, the cooling system comprising:
- a first cooling circuit in communication with the intercooler and the main oil cooler configurable in a first mode for directing an oil coolant portion of the first coolant flow into the main oil cooler and a intercooler coolant portion of the first coolant flow into the intercooler when a cooling capability of the first coolant flow in the first cooling circuit is sufficient for cooling the lubrication oil to achieve a desired oil temperature and for cooling the intake air to achieve a desired emission level produced by the power generation unit, and configurable in a second mode for limiting the oil coolant portion provided to the main oil cooler;
a supplementary oil cooler for cooling a portion of the lubrication oil connected in parallel with the main oil cooler;
a supplementary coolant source for providing a second coolant flow to the supplementary oil cooler; and
a second cooling circuit in communication with the supplementary oil cooler configurable in the first mode for limiting the portion of the lubrication oil provided to the supplementary oil cooler and configurable in the second mode for directing the portion of the lubrication oil to the supplementary oil cooler.

Abstract
A system, method, and computer readable media for controlling cooling in a diesel fueled power generation unit. The system includes a first cooling circuit configurable in a first mode for directing an oil coolant portion into main oil cooler and an intercooler coolant portion into an intercooler and configurable in a second mode for limiting the oil coolant portion provided to the main oil cooler. The system also includes a supplementary oil cooler for cooling a portion of the lubrication oil and a supplementary coolant source for providing a second coolant flow to the supplementary oil cooler. The system also includes a second cooling circuit in communication with the supplementary oil cooler configurable in the first mode for limiting the portion of the lubrication oil provided to the supplementary oil cooler and configurable in the second mode for directing the portion of the lubrication oil to the supplementary air oil cooler.
