Paper Abstract

A new technique which combines the high speed photography with the two-colour method was developed to measure the instantaneous distributions of temperature and soot co concentration of luminous flames. A couple of flame images is taken through two colour filters by a 35 mm high speed camera. The density distribution of each flame images which corresponds to brightness temperature distribution is processed by a Pseudo-colour system. The true tem-perature and soot concentration in the flame are calculated with the aid of two-colour principle. This technique was applied to a diesel engine. The instantaneous temperature distribution of the diesel flame showed that there exists a large uneveness amounting to 300 K.
