Problems solved by technology

The shape and space of this chamber are not conducive to combustion, and the combustion line is long; B: The seal of the triangular piston is located at the top of the three corners, and the sealing performance is poor. If it is not closed, the pressure ratio is small, and the combustion is not complete.
(3) The thermal work efficiency is low. In addition to the above-mentioned insufficient combustion reasons, the effective cross-sectional area of ​​the combustion chamber in the tangential direction of the main shaft is very limited, and the moment from the center of the main shaft is small, so the combustion expansion force acts on this area The smaller the resultant force, the smaller the torque
So its thermal efficiency is poor
(4) The service life is short, the seal of the triangular piston is at the top of the three corners, and its support and power output are realized through a pair of internal meshing gears
The eccentric structure and the wear of the gear meshing surface and the seal will inevitably cause the gap to gradually increase, thereby changing the relative position of the moving parts. With the prolongation of the service time, the sealing performance will decline faster, causing the leakage of the mixed gas in the rotor working chamber and the work. The blow-by between rooms increases, forming a vicious circle
This will inevitably lead to: A. Fuel cannot be fully burned, fuel consumption increases, and sewage discharge increases; B. Engine power becomes poor; C. The service life of the engine is shortened; D. Poor sealing and small pressure ratio are only suitable for gasoline engines, but not compression ignition diesel engine

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with accompanying drawing description and specific embodiment:

[0029] Design elliptical track groove (major axis - short axis) ÷ 2 = piston stroke S

[0030] Set the major axis of the elliptical orbital groove (12) of the elliptical orbital groove disc body at the vertical position, the lower apex is 0°, and rotate clockwise. When the starter drives the main shaft (1) to rotate, the cylindrical rotary cylinder The body (5) drives the positioning U-shaped fork (4), the transmission connecting rod (3), and the bearing at the lower end of the connecting rod (21) to rotate together synchronously. Due to the specific structural design of the elliptical track groove, the bearing (21) drives the transmission connecting rod (3 ) of the trajectory changes periodically with the position of the major and minor axes of the elliptical track groove (12), doing centripetal reciprocating motion. When 0-90...

Abstract

The invention relates to a single-row reciprocating piston type rotor engine, belonging to the field of power generating machines. The engine comprises a main shaft (1), an elliptic orbit groove disc body (2), a transmission connecting rod (3), a positioning U-shaped fork (4), a cylindrical rotary cylinder body (5), a rotary cylinder body end cover (6), a turning lever (7), a turning lever shaft (14), a traditional single cylinder engine nose (8), a piston connecting rod (9), a piston (10), a cylindrical enclosure (11) and the like, wherein the lower end of the transmission connecting rod (3) is provided with a bearing (21) inserted into an elliptic orbit groove (12); a horizontal elbow of the transmission connecting rod (3) passes through the tube wall of the cylindrical rotary cylinder body (5); a perforation is sealed by using a shaft seal (13); the horizontal elbow is connected with one end of the turning lever (7) by using the bearing; the piston connecting rod (9) is connected with the other end of the turning lever (7) also by using the bearing; the turning lever shaft (14) is fixed on the bottom of the rotary cylinder body (5) and is in positioning connection with the turning lever (7) by using the bearing. The invention has the advantages of simple and compact structure, few components, light weight, small volume, high efficiency, energy saving, convenience of maintenance and long service life and not only can be made into a gasoline engine but also can be made into a diesel engine.

Description

1. Technical field [0001] The invention relates to a novel internal combustion engine, which belongs to the field of power machinery. 2. Background technology [0002] The core technical point of the internal combustion engine widely used in the world today is to have a variable capacity mechanism, which can generate a sufficiently suitable compression ratio, complete the "Otto thermal function cycle", and output torque to do work. The key core technology is based on the The sealing problem between the piston and the cylinder wall in the unit volume, as well as the energy saving, emission and environmental protection problems. [0003] For more than a hundred years, the crank-connecting rod piston internal combustion engine, which has been dominant in the engine field, has become very mature. In recent years, the engine has entered the "electronic age", and the development of the traditional crank engine has almost reached the point of "perfect". However, the structure of t...
