发明名称 Method for determining a condition of an exhaust gas recirculation (EGR) system for an internal combustion engine
摘要 A method for determining a condition of an exhaust gas recirculation (EGR) system for an internal combustion engine. The method includes the steps of setting an EGR valve located on the EGR system to a first position, determining a first temperature value at a location on the EGR system, setting the EGR valve to a second position, determining a second temperature value at the location, and determining a condition of the EGR system as a function of the difference between the first and second temperature values.
