Abstract
An arrangement is disclosed wherein a luminosity detector and a pressure transducer are used in an internal combustion engine to determine the burned gas temperature and trapped mass within each combustion chamber of the engine on a cycle-to-cycle basis or over a period of cycles, and to predict NO.sub.x emissions from the engine. Also disclosed is an arrangement wherein the burned gas temperature in each combustion chamber can be determined using only the luminosity detector.
