Title:
INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2022/202843
Kind Code:
A1
Abstract:
In order to realize an internal combustion engine 10 capable of efficiently transmitting torque from a piston 12 to an output shaft 15 of a crank mechanism 14, the crank mechanism 14 of the internal combustion engine 10 has: a crank 21 having a crank pin 28; a movable member 22 that is movably connected to another end part of a connecting rod 13 and is rotatably connected to the crank pin 28; and a transmission mechanism 14 that includes a fixed gear 31 fixed to the movable member 22, and transmits a rotation force of the crank 21 to the movable member 22 via the fixed gear 31 so as to move the movable member 22 with respect to the connecting rod 13 and rotate the movable member 22 with respect to the crank 21. The movable member 22 is rotatably connected to the other end part of the connecting rod 13. The angle formed by the connecting rod 13 and the movable member 22 at the top dead center is in an angle range of 90°±70°.
