FIELD: gas turbine engineering.
SUBSTANCE: prechamber comprises diverging section for intensifying burning inside the combustion chamber and a number of pipes with openings that communicate the pipes with the combustion chamber on the front section of the prechamber to generate igniting torches. The front region of the converging section of the prechamber has at least one ring groove for control of the flame of the igniting torches arranged near the openings which are made in the pipes for stabilizing the main flame induced in the combustion engine.
EFFECT: reduced fuel rate consumption.
