Abstract:
A system and method are provided for estimating NOx produced by an internal combustion engine. The flow rate of fuel supplied to the engine and a plurality of engine operating parameters are monitored. NOx produced by the engine is estimated based on a product of the flow rate of fuel and a function of the plurality of engine operating parameters. The NOx estimate is stored in memory.
