The proposed method is distinguished from the known ones by the fact that the measuring of the temperature field is done by setting the thermocouple not in the exhaust measuring devices but in the ring-shaped space between the engine and the exhaust system.nThe undistorted temperature field to be measured in this section in no way differs from the temperature field in the operating system of the engine. The results of the measurements obtained are converted mathematically with the taking into account of the vortex of the gas stream.
