FIELD: engines and pumps.
SUBSTANCE: in compliance with this invention, air-fuel mix (AFM) temperature in KC is additionally measured. In case there is no AFM temperature increase during (1-2) s after the moment of starting A3, preset fuel flow rate in igniting KC is varied by alternating stepwise effect with frequency of 1 to 2 Hz and amplitude increasing from zero and 5%-steps of preset fuel flow rate in igniting KC. At the moment of igniting KC, registered in compliance with intermittent AFM temperature increase by over 70 K, fuel feed rate variation is terminated. Then fuel flow rate is registered for 1 to 2 s during igniting. Now fuel flow rate in increased in compliance with preset control program till engine idling.
EFFECT: higher quality of ACS operation, reliability and aircraft safety.
