摘要： A method includes determining a first NOx conversion efficiency (η) value and determining that a diesel exhaust fluid (DEF) level has increased a threshold amount. Further, the method includes determining a second NOx conversion η value and comparing the first NOx conversion η value and the second NOx conversion η value, determining a NOx conversion η change in response to comparing, and determining a DEF quality indicator in response to the NOx conversion η change.

摘要： A method and system for controlling the temperature of an engine system is disclosed. The method and system comprise measuring a coolant temperature of the engine system; measuring noise factors of the engine system; and controlling components of the engine system to provide for an optimal operation of the engine based upon the measured temperature and measured noise factors. Accordingly, a system and method in accordance with the present invention combines measuring noise factors such as coolant pressure or coolant concentration and the temperature and then adjusting the threshold values for factors such as fan on temperature and engine protection derate. In so doing the coolant temperature can be controlled within an acceptable range of values.
