FIELD: engines and pumps.
SUBSTANCE: invention relates to vehicle production. Proposed vehicle comprises ICE mounted in engine compartment, a fan arranged on radiator and incorporating impeller, drive motor and fan guide cowl. Fan cowl structural carcass represents a perforated or mesh-like part with noise-absorbing porous lining fitted on, at least, one of its sides. Note that the face surface of the said lining is coated, at least partially with noise-absorbing gas-and-water proof film. This lining can represent a flat-sheet glued to fan guide cowl with the help of sticky glue or thermally adhesive layer, or it can be attached thereon by mechanical fasteners.
EFFECT: improved operating and ecological characteristics due to noise reduction.
