ENHANCED ENGINE CONTROL BASED ON EXHAUST TEMPERATURE

摘要

A method is provided for controlling an engine (12) of a system (10) having an exhaust system (18) connected to the engine, and the exhaust system includes an exhaust gas cooler (19). The method includes sensing exhaust system temperature downstream of the exhaust gas cooler; comparing the exhaust syst em temperature to a temperature threshold that is less than 200 degrees Celsius ; and adjusting an engine control parameter when the exhaust system temperatur e exceeds the temperature threshold. A system for controlling engine operation is also provided.
