INFINITELY VARIABLE COMPRESSION RATIO OF TWO-CYCLE OR FOUR-CYCLE RECIPROCATION INTERNAL COMBUSTION ENGINE, AND SINGLE STROKE LENGTH MECHANISM OR DUAL STROKE LENGTH MECHANISM

摘要

To improve efficiency of an internal combustion engine by combining an adjustable variable compression ratio, explosion and exhaust stroke of long time, short intake, and compression stroke.SOLUTION: A balanced rotation mechanism of an internal combustion engine includes a mirror planetary gear assembly, a gear pin assembly 20, and a piston-connection rod assembly 27. The mirror planetary gear assembly has a first planetary gear assembly 2 and a second planetary gear assembly 3, and includes a sun gear 4, a main planetary gear 5, a plurality of auxiliary planetary gears 6, and a ring gear 7. The first planetary gear assembly and the second planetary gear assembly are mounted along a main rotation axis, offset from each other, and mirroring each other. The gear pin assembly is eccentrically connected between the main planetary gears. As a result, a direction of the gear pin assembly is changed by rotation of the sun gear, thus a height of a top dead center is changed.SELECTED DRAWING: Figure 2
