Abstract
A method and system for controlling engine temperature by derating torque output of the engine. The method and system operate in cooperation with an electronic control module which is programmable for controlling temperature in the engine by derating maximum engine torque output based on an engine temperature rate of change. This permits the derating to be finely tuned to maximize available torque.
