Method and Device for Adapting the Efficiency of a Cooler in the Return Circuit of Exhaust Gas in an Internal Combustion Engine |
摘要 |
A method for providing a specification about an efficiency of a cooler for recirculated exhaust gas in an internal combustion engine includes: measuring a temperature of the recirculated exhaust gas cooled by the cooler; and ascertaining the specification about the efficiency of the cooler as a function of the measured temperature of the cooled recirculated exhaust gas. With the aid of the specification about the efficiency of the cooler it is possible to determine a failure of the cooler or to calculate a temperature of the recirculated exhaust gas in order implement an engine control system of the internal combustion engine on the basis of a reliable temperature specification that is not influenced by lag effects.
