Engine over temperature protection

摘要

A method of operating an engine during an over temperature condition to protect the engine, an information recording medium incorporating a computer program implementing this protection method, and an electronic control module that performs this protection method are disclosed. A torque value representative of an engine generated torque is recorded in response to an engine temperature exceeding a protection temperature threshold. The engine torque is then reduced as a nonlinear function of the temperature signal and the recorded torque value to promote engine cooling.
