Detailed Description

The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein are for the purpose of describing particular embodiments only and are not intended to be limiting of the invention, and terms such as "and/or" as used herein include any and all combinations of one or more of the associated listed items; furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Example 1

1-5, an internal combustion engine includes a piston rod drive system including a piston rod having a rack attached thereto for driving the piston rod; the transmission system comprises a rack, the rack is connected with a half wheel A and a half wheel B, the half wheel A is coaxially connected with a gear B, the half wheel B is coaxially connected with a gear A, and a middle wheel is arranged between the gear A and the gear B; the air inlet and exhaust system comprises a piston connected with a piston rod, wherein the piston is arranged in a cylinder body, and an air inlet valve for air inlet, an exhaust valve for exhaust and a spark plug for ignition are arranged on the cylinder body.

In the embodiment, the driving system adopts a piston rod to connect with the rack, and the piston rod and the rack are fixedly connected, for example, a bolt, a threaded connection and the like, and can also be integrally formed, namely the rack and the piston rod are integrally manufactured; the piston rod pushes the rack to move, a hole is formed in the middle of the rack, a limiting piece is arranged inside the rack and used for limiting the deviation of the rack, namely, the movement of the rack is limited to linear movement; the motion of rack drives half round B and rotates, and half round B's rotation drives coaxial coupling's gear A and rotates, and gear A's rotation drives the intermediate wheel and rotates, and the rotation of intermediate wheel drives gear B and rotates, and gear B's rotation drives the rotation of coaxial setting half round A, and when the rack stretches out completely, the teeth of a cogwheel of half round A just entered into the tooth on the rack and meshes, then the piston rod compresses the mist.
