ABSTRACT:
A method of regulating combustion by rapid-response monitoring of the gaseous effluents leaving a combustion chamber, especially the chamber of an internal-combustion engine, includes the steps of emitting ultraviolet radiation to a zone of small volume traversed by at least part of the gaseous effluents leaving the combustion chamber; receiving at least part of the ultraviolet radiation which has passed through this zone; measuring the degree to which the ultraviolet radiation has been absorbed by a chemical compound contained in the gaseous effluents; and governing at least one parameter influencing combustion within the combustion chamber as a function of the degree of absorption.
