A process for providing a real-time estimation of in-cylinder NOx production rates during a combustion process in an internal combustion engine. The process employs a model that takes into account fundamental in-cylinder variables such as temperature, pressure and oxygen content. The process can be used with calibrated or uncalibrated internal combustion engines and can be used to capture the effects in variations of engine speed, engine torque, EGR, injection timing, and engine boost levels.
