SINGLE-CYLINDER FOUR-STROKE INTERNAL COMBUSTION ENGINE Russian patent published in 1999 - IPC

Abstract RU 2136903 C1

FIELD: mechanical engineering; internal combustion engines of low power output for use as power units in small-size agricultural machinery and vehicles. SUBSTANCE: single-cylinder four-stroke internal combustion engine has cylinder head 1, intake valve 2 with rocker 3 covered by cover 4. Shaft 5 is fitted in side wall of cover 4. Lever 6 rigidly secured one end of shaft 5 is coupled with pull-back spring 7, other end of spring being secured in bracket 8. Free end of shaft 5, arranged over arm of rocker 3 pointed to intake valve 2, is made in form of semicylinder 10 with cut parallel to axis of semicylinder and square to its diametric plane. Width of cut is equal to (0.15-0.2)d where d is diameter of shaft. EFFECT: reduced overall dimensions, simplified design, improved starting characteristics of engine. 2 cl, 5 dwg
