Technical Field

The invention belongs to the technical field of internal combustion engines, and particularly relates to an internal combustion engine.

Background

The internal combustion engine is widely applied, the internal combustion engine is adopted for driving a motor vehicle, the internal combustion engine adopts a crank structure in the prior art, namely a piston rod adopts the crank structure, the structure has the defect of short stroke, in addition, due to the crank structure, when the internal combustion engine moves back and forth, the cylinder wall of the internal combustion cylinder is stressed, the cylinder body abrasion of the internal combustion cylinder is accelerated, the service life is also reduced, and aiming at the defects, the internal combustion engine which reduces the internal wall abrasion of the internal combustion cylinder, increases the stroke and has a reasonable structure is needed to be developed; therefore, it is very important to develop an internal combustion engine with reasonable structure, which can reduce the wear of the inner wall of the internal combustion cylinder, increase the stroke.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide the internal combustion engine which reduces the abrasion of the inner wall of the internal combustion cylinder, increases the stroke and has a reasonable structure.

The purpose of the invention is realized as follows: an internal combustion engine comprising

The piston rod driving system comprises a piston rod, and the piston rod is connected with a rack 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.

And when the half wheel B is disengaged from the rack, the half wheel A enters the rack for engagement.

The half wheel B, the gear A, the middle wheel, the gear B and the half wheel A form a transmission system.
