Abstract
A method is provided for controlling an engine of a system having an exhaust system connected to the engine, and the exhaust system includes an exhaust gas cooler. The method includes sensing exhaust system temperature downstream of the exhaust gas cooler; comparing the exhaust system temperature to a temperature threshold that is less than 200 degrees Celsius; and adjusting an engine control parameter when the exhaust system temperature exceeds the temperature threshold. A system for controlling engine operation is also provided.
