FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to crank mechanisms of internal combustion engines. Internal lower side of pistons skirt is provided with groove with antifriction ring, underpiston space is provided with cylindrical guide bushing with slots to pass bosses with piston pin and connecting rod, and flange clamped between flanges of crankcase and cylinder by means of bolts. Invention is aimed at decreasing overall dimensions of mass of movable parts at provision of simple design. Overall dimensions are decreased owing to use of inner space of piston as crosshead which makes it possible to built double-row offset engines featuring reduced mass and dimensional characteristics, as compared with vee-type engines. EFFECT: reduced overall dimensions and mass of engines. 9 dwg |
