FIELD: engines and pumps.
SUBSTANCE: device of combustion chamber with adjustable holes in flame tube for comprises fuel feed unit, fire tube with holes for air supply, mixing zone, which are arranged in common housing. Flame tube is placed inside housing and located along axis of combustion chamber. Flame tube consists of inner fire tube, which is external flame tube with dosing elliptical or tangential holes made at angle of 30-45° relative to tangent to surface of flame tube to swirl air flow and reducing its resistance to vary hole area. Made in internal and external flame tubes holes can be completely aligned and have same size.
EFFECT: invention provides high degree of homogenisation of fuel-air mixture in wide range of modes of engine operation, possibility to work with different types of fuel due to production of different parameters of air supply.
