Patent ID: 8214115

Claim:
A method of managing heat produced by an internal combustion system including an internal combustion engine coupled to a transmission, the method comprising: monitoring an engaged drive ratio of a transmission during operation of an internal combustion system, the transmission including at least a low drive ratio and a high drive ratio; storing in a controller a plurality of different performance curves including a first performance curve and a second performance curve, each performance curve selectable by the controller to operate the internal combustion engine; selecting a performance curve from the plurality of different performance curves based in part on the engaged drive ratio monitored from the transmission; operating the internal combustion engine in accordance with the performance curve selected; cooling the internal combustion engine with a cooling system rated for engine operation under the second performance curve; wherein the first performance curve is selected when the transmission is engaged in the low drive ratio and the first performance curve increases torque output of the internal combustion engine; and the second performance curve is selected when the transmission is engaged in the high drive ratio and the second performance curve reduces torque output of the internal combustion engine.
