Embodiment 1

[0065] Parameters k=11, e=0.006m, q=4.5, assuming that each sealing pin column contains 4 sealing pins, and the effective distance of each sealing pin is 0.0016m, this is used as an example to describe the specific operation mode of the engine.

[0066] Since the overall shape of the cylinder body is 120 degrees rotationally symmetric, only 1 / 3 of it needs to be considered in this embodiment. Such as image 3 As shown, the sealing pin column 7 composed of 4 sealing pins is arranged vertically on the isolation belt 6, and the sealing pin column 7 is arranged equidistantly along the longitudinal direction. Pins 7.1-7.4. Such as Figure 5 As shown, since the distance between each sealing pin and the rotor 3 is different when the rotor 3 is in different positions, it is considered that the distance between each sealing pin and the rotor 3 changes during one cycle of the rotor 3 rotation, The first four curves in the figure represent the change curve of the distance between the ...

Abstract

The invention discloses an ellipse-like rotor engine with high sealing performance. The engine comprises an upper end cover, a lower end cover, a rotor, three combustion cavities, three sections of isolation belts, an oil injection ignition device, sealing pin rows and an eccentric driving shaft. According to the technical scheme, a new design scheme is provided for molded lines of the rotor and acylinder body, on the basis, the sealing pin rows are introduced to seal transition areas among the different combustion cavities, the engine can well prevent the structure abrasion effect, the sealing performance among the combustion cavities is effectively enhanced, gas leakage among cylinder bodies is reduced, and the designed molded lines and sealing mode can increase the design error marginof the engine and reduce the machining difficulty of the engine, so that the production cost of the engine is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a quasi-elliptic rotor engine with improved sealing performance. Background technique [0002] The rotary engine is a novel internal combustion engine that appeared in the 1950s. Compared with the general reciprocating piston internal combustion engine, the rotary engine has the advantages of small size, high power-to-weight ratio, and low vibration and noise. Among them, the triangular rotor engine is a more commonly used scheme. This engine is also called Wankel engine. The meshing drives the rotor to do planetary motion around the cylinder, which is a four-stroke engine. [0003] In order to ensure the tightness of the engine during operation, the three protruding points on the triangular rotor of the traditional triangular rotor engine will always rotate at a high speed in a state of keeping close to the cylinder wall. As the service time prolongs, the sealing p...
