The paper presents the results of studies of gasoline and diesel fuel diffusion combustion using IR thermography methods. Experimental results of the effect of small amplitude pressure pulsations with various frequencies on the spectra of temperature changes in the flame and other characteristics are obtained. It is shown that the effect of pressure pulsations with certain frequencies leads to a change in the flame height, fuel burning-up rate and the appearance of characteristic frequency maximum in the spectra of temperature changes in the flame.
