Abstract
The paper presents the effect of low amplitude acoustic pulsations on the temperature field in a flame formed during gasoline combustion. The analysis of the high-temperature inhomogeneities distribution in the flame plume is carried out. It is shown that the effect of acoustic vibrations on the flame plume causes a change in the height of the flame and a change in the rate combustion of the fuel. After analyzing the spectra of temperature changes, the characteristic pulsations are noticed. They differ, depending on the flame zone.
