AIR-COOLED SINGLE-CYLINDER INTERNAL COMBUSTION ENGINE

摘要

FIELD: mechanical engineering; small-scale mechanization facilities. SUBSTANCE: air-cooled small-size internal combustion engine has finned cylinder with head, centrifugal fan with impeller made integral with flywheel and installed on end of crankshaft. Fan guide casing consists of two parts with split square to crankshaft axis. Part of casing is installed on seat projection of engine crankcase and is provided with outer flange and inner support for accommodating starter. One part of guide casing is installed on other part and is provided with hole for taking in cooling air and inner partition for directing cooling air to cylinder and head of internal combustion engine. EFFECT: increased efficiency of fan, simplified design of internal combustion engine. 2 cl, 3 dwg
