mechanical engineering; fuel systems of internal combustion engines. SUBSTANCE: fuel tank of piston engine is secured on engine cylinder block-and-crankcase unit by means of intermediate bracket in fastening holes of which flexible rubber bushings are installed through ring groove on outer surface. Rubber bushings have through hole coaxial to ring groove. Tubular spacer bushing is fitted in hole of flexible rubber bushing. Fastening bolt is passed through hole in spacer bushing. Height of tubular spacer bushing is less than height of flexible rubber bushing in free state by valve of preliminary deformation of height of flexible rubber bushing after tightening of fastening bolt. EFFECT: improved reliability of engine owing to reduction of fuel tank vibration intensity. 2 cl, 4 dwg
