FIELD: manufacture of engines for dampening vibrations arising during vibration combustion in prechamber. SUBSTANCE: at development of vibrations selected by vibration combustion, dissipation of vibrational energy is performed in flame stabilizers 6 at air motion near open end 7 of flame stabilizer 6 which is turned at frequencies of first modes of vibrations of prechamber through selecting their length as quarter-length-wave resonators. Relationship of difference of radii of open and closed ends to radius of prechamber ranges from 0.6 to 0.9. EFFECT: enhanced reliability. 1 dwg
