Abstract
A means and method for measuring and controlling smoke emissions from an internal combustion engine using a luminosity probe which measures the luminosity of soot in a combustion chamber of the engine. The luminosity signals generated by the probe are then used to measure smoke emissions based on an equation developed by the inventors which correlates the actual smoke being emitted from the exhaust with a predicted smoke emission value resulting from the luminosity signals. This smoke emission measurement can, in turn, be used in an engine control loop to control smoke emissions.
