AIR SUPPLY SYSTEM OF INTERNAL COMBUSTION ENGINE Russian patent published in 1998 - IPC

Abstract RU 2115822 C1

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed invention relates to intake systems of internal combustion engines furnished with working medium heating devices. System has air cleaner with mixed air pipe 2 connected to air cleaner chamber. Cold and heated air branch pipe is provided with deflector enclosing outer wall of outlet pipeline. Deflector in form of solid casing is made of noise and vibration damping porous material permeable to gas and is installed either without clearance or with closed circular clearance enclosing at least part of outer wall of outlet pipeline. Conduction of casing structure can differentially increase from cut towards part of porous casing farthest from cut. EFFECT: reduced intake noises. 6 cl, 4 dwg
