Problems solved by technology

However, when the rigid rotor rotates in the circular cylinder, the volume of the working chamber will not change, and the stroke cycle of the four-stroke internal combustion engine cannot be realized, so a deformable rotor must be used.
The most commonly used implementation scheme for deformable rotors is the structure with sliding vanes, but the contact between the sliding vanes and the cylinder wall in the sliding vane scheme is still tangential, which makes it difficult to achieve strict sealing and is not suitable for internal combustion engines

Abstract

The invention relates to a planet gear angle changing rotator generator that belongs to mechanism manufacturing field. The invention uses two pairs of rotating fans to separate the cylinder into four working cavities. The angular velocities of the two pairs of fans are rotating at the same cycle and the different phase while one-way rotating, and make the inclination cyclic vary. Thus, the four strokes of the four stroke gas engine would be realized. The feature of the invention is controlling the phase of the rotating fans by planet gear and outputting torque to rotating shaft by planet gear. The sealed surface of the work cavities are surface contacted sealing. And the structures referred are standard structure. Thus, the better torque feature, sealing feature, compression ratio, and the lower manufacturing cost would be achieved.

Description

1 technical field [0001] The invention relates to a four-stroke rotary internal combustion engine, which belongs to the field of machinery manufacturing. 2 background technology [0002] The four-stroke internal combustion engine currently in the mainstream in application is a reciprocating piston internal combustion engine, while the rotary four-stroke internal combustion engine has only reached a practical level with a triangular rotor engine (Wankel engine). Since the cylinder inner wall profile of the triangular rotor engine is a cycloid, not a constant curvature curve, the contact between the rotor and the cylinder wall can only be tangential contact, so there is a big difficulty in sealing the working chamber formed between the rotor and the cylinder wall. As a result, the triangular rotor engine has low compression ratio, high fuel consumption, and large rotor wear, so that its theoretical advantages cannot be fully utilized, and it cannot replace the reciprocating pi...
