CARBURETOR FOR INTERNAL COMBUSTION ENGINE Russian patent published in 2002 - IPC

FIELD: mechanical engineering; fuel equipment of internal combustion engine. SUBSTANCE: proposed carburetor has body whose bottom is provided with hemisphere for removal in lower part of bottom. Air guide elements are made in form of branch pipes whose lower ends are connected with space between body bottom and partition with holes. One of air guide branch pipes has excess air spool with electric drive made for closing the branch pipe and installed on intake manifold. Other air guide branch is provided with air choke which has common control element with throttle valve, this element being made in form of common tie-rod. Number of different shape plates is installed between cover and bottom of body in different planes, part of plates being hollow. Spaces of plates communicate with space of body side member which communicates with space of engine exhaust manifold. Body cover is provided with valve. Mixture feed-out branch pipe connects space of inner chamber with space of intake manifold under throttle valve. Carburetor has electronic control unit, and at least part of controls is electrically coupled with electronic control unit. EFFECT: improved homogeneity of fuel-air mixture prepared by carburetor, reduced overall dimensions of carburetor, elimination of influence of carburetor tilting onto carburetion process, improved temperature compensation. 4 dwg
