Embodiment Construction
[0037] Figure 1~Figure 5 The external convex internal two-phase cam rolling transmission internal combustion engine shown is composed of exhaust valve (1), cylinder head (2), cylinder (3), intake valve (4), cylinder block (5), piston (6), Push rod (7), spring (8), roller (9), output shaft (10), convex inner two-phase inner cam (11), rolling movable tooth (12), movable tooth rack (13), center Wheel (14) etc. are formed. Eight air cylinders (3) are evenly distributed circularly symmetrically around the two-phase inner cam (11) which is convex inside, and the angle between two adjacent air cylinders is 45°. There is a piston (6) in each cylinder (3), one end of the push rod (7) is solidified with the piston (6), and the other end is equipped with a roller (9), and the push rod (7) is connected with the outer convex inner The two-phase internal cams (11) change from sliding friction connection to rolling friction connection through rollers (9). One end of the spring (8) is fixed...
