Double-cylinder circular ring type cylinder internal combustion engine

Abstract

The invention relates to an internal combustion engine of a circular cylinder body with double cylinder bodies and belongs to a power machine, in particular to a rotary piston-type internal combustion engine. The jointing surface between a piston and the wall of the cylinder body of the internal combustion engine has a cirque structure with the same radius; the rotating center of the piston and the center of the circular cylinder body are consistent; the piston is in driving connection with a clutch which is arranged on a rotary mainshaft; the piston is arranged between the inner concentric circular surface and the outer concentric circular surface of the circular cylinder wall; a piston arm is of a circular arc shape; the tail end of the piston arm is fixed with one end of a connecting rod; the other end of the connecting rod is connected with the clutch of the rotary mainshaft; the piston is in driving connection with a returning mechanism of a tapered gear set, that is two parallelcylinder bodies share the same rotary mainshaft; the connecting rod of each cylinder body is connected with a corresponding tapered gear; a transition tapered gear is engaged between two relative tapered gears; and two tapered gears are connected with the clutches respectively. The internal combustion engine has the advantages that the internal combustion engine has a simple structure, reasonablestress of the piston, no dead center of power transmission, large output torsional moment and small abrasion to a moving part.

Description

[0001] The original filing date of the divisional case: 2006.1.12 [0002] Divisional original application number: 200610010629X [0003] The name of the original invention and creation of the divisional case: circular cylinder internal combustion engine technical field [0004] The invention belongs to power machinery, in particular to a rotary piston internal combustion engine. Background technique [0005] The traditional internal combustion engine is a well-known internal combustion engine with a crank-and-link mechanism, which converts the linear reciprocating motion of the piston in the cylinder block into the rotary motion of the crankshaft, and then outputs it to the working machine. Since the angle between the connecting rod and the moving direction of the piston changes at any time, a large part of the force transmitted along the connecting rod to the hinge point is a radial force, which does not make the rotating main shaft do work, but only generates axial press...

Problems solved by technology

It is smaller in size, lighter in weight, and has lower vibration and noise, but its narrow and long combustion chamber shape is not conducive to complete combustion, and the flame propagation path is longer, which increases fuel and oil consumption and lower thermal efficiency. Moreover, the rotary engine can only use ignition type, not compression ignition type, that is, diesel oil cannot be used. In addition, the processing and manufacturing technology of rotary engine is high, the cost is relatively expensive, and it is difficult to promote. Therefore, like the internal combustion engine with crank connecting rod mechanism, it belongs to high energy consumption. , highly polluting products
