ABSTRACT:
An internal combustion engine having a luminosity detector and an arrangement for measuring certain operating and running parameters such as peak heat release rate in the combustion chamber, NO.sub.x emissions and air/fuel ratio is provided. An arrangement is also disclosed wherein the engine's adjustable parameters can be varied in response to the luminosity signal or in response to the measured operating parameters so as to provide better running of the engine and/or reduce cycle to cycle variation.
