Embodiment 1

[0039] Example 1: Four-stroke eccentric rotary engine.

[0040] Such as Picture 1-1 As shown, the present invention mainly includes a cylinder block 1 and an eccentric rotor 2 arranged in the cylinder block 1.

[0041] The cylinder 1 has a cylindrical inner cavity penetrating back and forth for setting the eccentric rotor 2. Such as image 3 As shown, the eccentric rotor 2 includes an eccentric shaft 19, a rotor bearing 17 sleeved on the eccentric shaft 19, and a rotor sealing ring 18 sleeved on the rotor bearing 17, the central axis of the eccentric shaft 19 and the central axis of the cylindrical cavity On the same straight line, the outermost distance of the outer side of the rotor seal ring 18 from the central axis of the eccentric shaft 19 (the maximum rotation radius of the eccentric rotor 2) is slightly smaller than the radius of the inner cavity. When the eccentric rotor 2 rotates, the existence of the rotor bearing 17 can reduce the mechanical wear between the rotor seali...

Embodiment 2

[0048] Embodiment 2: The work method of a four-stroke eccentric rotary engine.

[0049] Taking the four-chamber eccentric rotary engine described in Example 1 as an example, the four chambers are sorted in a clockwise order, namely A, B, C, D, and the upper left chamber is chamber A. Assuming that the center of the movable partition 3 between the chamber A and the chamber B is the 0° position of the cylinder 1, the operating angle of the eccentric rotor 2 refers to the distance between the outer side of the rotor sealing ring 18 of the eccentric rotor 2 and the eccentric shaft 19 The angle corresponding to the most distal point of the axis on the cylinder 1. The working method is as follows (the working procedures of A, B, C, and D chambers are the same and not related to each other. The following only describes the working process of chamber A. The figure does not show the inlet valves and inlets of chambers C and D. Exhaust valve).

Embodiment 3

[0056] Example 3: Four-stroke continuous combustion eccentric rotary engine.

[0057] The structure of the engine is based on the engine described in Embodiment 1, and is obtained by improving the motion control method of the movable partition 3 and the number of spark plugs.

[0058] Such as Figure 5-1 As shown, a spark plug is provided in the upper left chamber, which is an ignition chamber, and no spark plug is required in the remaining chambers. The movable partition 3 located on the side of the intake door 12 of the ignition chamber is a closed partition, which always contacts the rotor sealing ring 18, and the remaining movable partitions 3 are all openable partitions. A pin shaft 16 perpendicular to the front end surface is provided on the front end face of the outer end of the openable partition, and a partition guide plate 4 (such as a partition guide plate 4) is provided on the eccentric shaft 19 between the cavity cover 5 and the front end cover 8. Figure 1-2 ), the pa...

Abstract

The invention relates to an eccentric rotor engine and a working method thereof. The eccentric rotor engine structurally comprises a cylinder body and a cylindrical eccentric rotor arranged in the inner cavity of the cylinder body, wherein the cylinder body is provided with a plurality of movable partition plates, the movable partition plates are in contact with the side wall of the eccentric rotor and divide the inner cavity into a plurality of independent cavities, the movable partition plates perform reciprocating motion in strip-shaped through grooves with rotation of the eccentric rotor,the volumes of the cavities correspondingly change, and the working process of air inflow, compression, ignition, expansion working and exhausting is correspondingly completed. Multiple working modessuch as external air compressor two-stroke continuous combustion cycle, internal air compression two-stroke cycle, four-stroke re-expansion cycle and common four-stroke cycle are designed according todifferent air inlet modes and different movable partition plate controls. The eccentric rotor engine is simple and durable in structure, is good in torque under maximum explosion pressure, and is stable and sufficient in working medium combustion, high in output power, high in power density, low in hazard waste emission, high in fuel economy, stable in operation, small in shake, low in noise andhigh in heat efficiency.

Description

Technical field [0001] The invention relates to a rotary engine and a working method thereof, in particular to an eccentric rotary engine and a combustion work method thereof. Background technique [0002] The reciprocating piston internal combustion engine occupies a dominant position in the power category of the world today. It is widely used as the power of automobiles. However, due to its own complex structural characteristics, the further development of the internal combustion engine is greatly restricted. The reciprocating inertial force and moment of inertia caused by the reciprocating motion of the piston group of a reciprocating piston internal combustion engine cannot be completely balanced, and this inertial force increases according to the square of the speed. When the speed increases, the inertial load acting on the bearing and certain The stress of the parts increases significantly, and the vibration and noise caused by the unbalanced force are further deteriorated,...
