Three-way double two-stroke spiral heat engine

Abstract

The invention relates to a three-way double two-stroke spiral heat engine, which comprises three groups of internal-combustion engine components with the same structure. The spiral heat engine is characterized in that: each internal-combustion engine component consists of a cylinder body, a throttle sub-cylinder valve and a cam piston, wherein the cross section of the inner cavity of the cylinderbody is circular; the cross section of a bulge part of the cam piston is a sector surface accounting for one half of circumference; the cam piston is arranged in the inner cavity of the cylinder body, and the side surface of the bulge part of the cam piston clings to the side wall of the inner cavity of the cylinder body; the cam piston can do circular movement in the cylinder body; the throttle sub-cylinder valve is arranged on the cylinder body, and the front end of the throttle sub-cylinder valve extends into the inner cavity of the cylinder body and is supported against the side wall of the cam piston all the time under the action of a spring force; and both sides of the throttle sub-cylinder valve are provided with an air tap communicated with the inner cavity of the cylinder body respectively. The spiral heat engine has the advantages of small volume, simple structure, high heat energy conversion rate, high compression ratio, easy maintenance, high stability, small vibration andlow noise.

Description

Technical field: [0001] The invention relates to a three-way, double-two-pass spiral heat engine, in particular to a coaxial, same-direction, synchronous force transmission; double-two-pass circular motion heat engine, which belongs to the field of internal combustion engines. Background technique: [0002] Currently, reciprocating engines, rotary engines and the like are known. [0003] 1. Reciprocating engines are further divided into two-stroke engines and four-stroke engines. The working principle is composed of four stroke cycles: intake stroke, compression stroke, combustion stroke, and exhaust stroke. These four strokes are completed by the linear reciprocating motion of the piston, through the connecting rod and the crankshaft. [0004] There is following shortcoming in above-mentioned compound engine: [0005] 1. The piston reciprocates to complete four strokes, of which only one stroke is the work stroke, and the other three strokes are completed by inertia (illu...

AI Technical Summary

Problems solved by technology

Therefore, some machines have to overcome inertia, while other machines have to use inertia, thus restricting the development.

[0007] 3. There are many and complicated parts, and the result is increased friction

[0008] 4. Generally speaking, the reciprocating engine has the disadvantages of low conversion rate, large volume, complicated mechanism and inconvenient maintenance

[0011] 1. High fuel consumption, difficult to meet exhaust emission standards, and difficult to control compression ratio

[0012] 2. After the engine has been used for a period of time, it is easy to cause air leakage due to the wear of the oil seal material, which greatly increases fuel consumption and pollution

Its unique mechanical structure also makes this type of engine more difficult to repair

[0013] 3. High precision and high cost
