FIELD: engines.
SUBSTANCE: invention can be used in internal combustion engines with chargers. Low pressure air supply system for engine (4), having charger (10) includes low pressure atmospheric air inlet opening (9), charger air compressor (11), air filter (8), low pressure air channel (15) and sound-proofing device (20). Air filter (8) filters air supplied via low pressure air inlet opening. Low pressure air channel (15) is connected with air filter (8). Soundproofing device (20) is connected with low pressure air channel (15) on inlet end, is located near charger air compressor (11) inlet. Soundproofing device (20) includes housing (21) and chamber. Soundproofing device (20) chamber is located around part of housing (21) and functionally connected with air duct, formed by housing (21), through plurality of bypass openings formed by elongated holes, which long edges are parallel to air flow path through air channel. Invention discloses vehicle with engine containing low-pressure air supply system.
EFFECT: technical result consists in noise level reduction.
