FIELD: mechanical engineering; carburetor engines. ^ SUBSTANCE: proposed fuel system of carburetor engine includes fuel feed system, intake manifold, air cleaner, carburetor, air swirler containing at least one base with fitted-on guides made in form of plates for swirling passing air flow in plane square to axis of carburetor mixing chamber. Guide of air swirler are made in form of starting plates arranged tangentially to carburetor mixing chamber. Height of guides is equal to height of air clearance housing. ^ EFFECT: simplified manufacture and mounting of air swirler, provision of possibility of use said system on engine with complex shape of air cleaner housing. ^ 2 dwg
